4. Installation
4.1 Location
The 1050 Control is designed for installation in climate controlled living
spaces. Place the unit in a central location with good circulation.
For proper temperature sensing, avoid exposing the 1050 Control to heat
radiated from lamps, sun light, fireplaces or any other radiant heat source.
Avoid locations close to windows, behind doors or alcoves with poor air
circulation, adjoining outside walls, or doors that lead to the outside.
Select a location that prevents the 1050 Control from being directly exposed
to air currents from supply registers or ceiling fans. Mount the 1050 Control
on a section of interior wall that does not contain hot or cold water pipes or
duct work.
Important: The 1050 Control utilizes a 7″ color touch screen. This screen
generates heat which is vented out the top of the 1050 Control utilizing
natural convection. If an air source is directed at or from above, the indoor
temperature may be biased.

4.2 Network Connections
To take advantage of the full range of features on the 1050 Control, it should
be connected to the Internet. This is possible using either a wireless or a
wired connection.
Wireless Connections
If the 1050 Control will be connected to the Internet using the built-in
wireless feature, choose a mounting location that ensures adequate signal
strength from the Internet router.
Tips to Help Maximize Signal Strength:
— Mount the 1050 Control within 30 feet of wireless router
— Install 1050 Control with no more than three interior walls between it and
the router.
— Locate the 1050 Control where electromagnetic emissions from other devices,
appliances, and wiring cannot interfere with system communication.
— Locate the 1050 Control in open areas, not near metal objects, or near
structures. (i.e. doors, appliances, entertainment centers or shelving units).
— Locate the 1050 Control further than two inches away from any pipes, duct
work, or other metal obstructions.
— Locate the 1050 Control in an area which minimizes metal obstructions and
concrete or brick walls between the 1050 Control and the router.
Refer to the 1050 Control’s User Guide for additional information on
connecting to the Internet.
Wired Connections
The 1050 Control may be connected to the Internet using its built-in RJ-45
connector. When using a wired connection, verify that a CAT 5 or better
Ethernet cable with a male RJ45 connector is present from the router to the
1050 Control.
Incorrect Placement Problematic Air Patterns
Locate the control in an area with minimal air flow patterns thereby avoiding
interuption of natural heat dissipation

18-HD80D1-6F-EN
4.3 Mounting
Follow these steps to mount the 1050 Control to the wall.
1. Turn OFF all power to heating and cooling equipment.
2. If an existing thermostat is being replaced:
a. Remove the existing thermostat from the wall.
b. Record color and terminal marking of each wire.
c. Disconnect the wires from the existing thermostat being careful not to
allow them to fall back into the wall.
3. Route the wires through the opening on the Sub-base.
4. If using a wired Internet connection, route the Ethernet cable through the
opening. See Figures 2 and 3.
5. Place the Sub-base against the wall in the desired location and mark the
wall through the mounting holes.
6. Drill the holes in the wall where marked.
7. Mount the Sub-base to the wall using included mounting screws and drywall

4.4 Wiring
1. Adjust the length and position of each wire to reach the proper terminal
on the connector block of the Sub-base. Strip 1/4″ of insulation from each
wire. Do not allow adjacent wires to short together when connected. If
stranded thermostat cable is used, one or more strands will have to be cut to
allow the cable to fit connector. Solid conductor wire larger than 18 ga will
not fit the connector.
2. Match and connect control wires to the proper terminals on the connector
block. Refer to Field Wiring Diagrams included in this document.
3. Push excess wire back into the wall and seal the hole to prevent air
leaks. NOTE: Air Leaks in the wall behind the 1050 Control can cause improper
operation.
4. Attach the 1050 Control to the Sub-base.
5. Turn ON power to the heating and cooling equipment.

minutes for up to 4 zones and 20-24 minutes for 5 zones or more) Theres an
additional setting if Auto Detection is selected. Zone Size Adjustment Normal,
Less Aggressive, More Aggressive. Less Aggressive setting results in slightly
smaller zone sizes with reduced air flow while More Aggressive setting results
in slightly larger zone sizes with increased air flow.
Manually input the zone sizes or edit the calculated zone sizes. The sum of
the zone sizes must be 100% or greater for zoning to proceed. See the Manual
Zone Sizing table on the following page..
Select which zones are Voting zones. Zones sized 25% or less are forced to
non-voting zones. Only voting zones are allowed to call for heating or cooling
operation. NonVoting zones will receive capacity only when a voting zone is
also requesting capacity.
The air flow offset is the difference between the design cooling air flow (CFM
per ton x outdoor unit tonnage) versus the design heating air flow (max
heating air flow setting). The 1050 Control uses this offset to calculate and
manage excess air.

Installation Guide
MANUAL ZONE SIZING
Auto Zone Sizing is the optimal way to determine the amount of air flow into
each zone, but this process is not mandatory. Zone sizes can be set manually
using the following guidelines.
EXAMPLE (highlighted below): A 2-zone, 3-ton AC system is configured to move
1200 CFM. Zone 1 has a 12″ zone damper and Zone 2 has a 16″ zone damper. The
Normal sizing strategy would set Zone 1 at 43% and Zone 2 at 81%. If Zone 1
had two dampers (6″ and 10″) the zone size % should be added together (11% &
33%) and set to 44%.

5.4 Indoor Sensor Setup
The Indoor Temperature Setup screen allows the technician to view, edit and
assign the correct temperature sensor for each zone. It is available in the
Technician Access menu. On the left side of the screen, Zones will be
displayed. On the right side, available sensor will be shown.
IMPORTANT: Installer Setup>Zoning must be done before assigning sensors to
zones. All equipment and dampers should already be assigned or discovered .
Assigning Sensors
To assign a sensor to a zone,
1. Select the corresponding zone on the left side of the screen.
2. Next, select the appropriate sensor on the right side of the screen.
3. Press ASSIGN.
The sensor will be assigned to a zone, and it will now appear on the left
side.
Multiple sensors (communicating or non-communicating) can be wired or
addressed to each zone, but only one sensor can be assigned to a zone. To
change the assignment, select the appropriate zone, then select the desired
zone sensor and press Apply.
Note – If the 1050 is being used as a zone sensor it must be addressed as Zone
- If a wired remote sensor (ZZSENSAL0400A) is connected to the 1050 RS terminals
and assigned as the indoor temperature sensor, the onboard temperature sensor
as well as the onboard humidity sensor of the 1050 is disabled. The onboard
humidity sensor can be re-enabled in the Installer Settings (Installer Setup >
Sensors > Thermostat Humidity Sensor settings.
5.5 Service Reminders
Reminders can be enabled to trigger a notification when the configured reminder expires and a message will be displayed across the top of the display. The reminder is time-based and can be configured on system run time or calendar days. Reminders can be configured for humidifiers, filters, ventilation systems, UV lights and HVAC system maintenance. The type of reminders available are based on the accessories enabled in the installer settings.
5.6 Dealer Code
When a 1050 Control is connected to Trane Home, a Dealer Code can be entered
to auto-populate the dealer’s contact information and logo. The code is the
dealer’s registered phone number listed on ComfortSite. A dealer can upload a
logo by selecting Tech Support from the Home page of ComfortSite, then select
Dealer Logo Management and upload logo. File size should not exceed 3MB.
5.7 Software Updates
To take full advantage of the features and benefits of the 1050 Control, the
latest software revision should be installed.
When the 1050 is connected to a Trane Home account, software updates will
occur automatically and do not require user intervention.
The software may also be manually updated.This procedure requires a computer
with an Internet connection, a USB Flash Drive and the included USB connector.
1. From your ComfortSite account, go to Tech Support > Trane Tools > TZON1050
Firmware Upgrade.
2. Follow the onscreen notes to download the software to a USB Flash Drive.
3. Once downloaded to your Flash Drive, connect Flash Drive to provided USB
to Micro USB connector.
4. Insert connector to 1050 Control and navigate to the Software Upgrade
screen (Menu > Settings > SW Upgrades)
5. Follow the onscreen prompts to complete the upgrade process.

6. Basic Operation Non-Zoned
6.1 PI Control
The 1050 Control uses proprietary control schemes to provide comfort and
energy efficiency. The 1050 Control senses indoor temperature and determines
capacity needed based on the following parameters:
· Mode of operation
· Proportional Error – distance from setpoint
· Integral Error – Time away from setpoint
72º
Set Point Temperature
2 Seconds
Integral Error
A
Room Temperature

A = Proportional Error B + C + D… = Integral Error
6.2 Load Value
The 1050 Control uses proportional plus integral error to determine the amount
of capacity required. The calculated capacity is displayed as load
value.LoadValue is a numerical representation of the needed capacity to
maintain setpoint. The load value range is dependent on the applied system.

A Load Value of 50 represents a request of 50% demand for single stage cooling units (“Y”) or 50% demand for stage one of multistage cooling units (“Y1”).
A Load Value of 150 represents a request of 100% demand for stage one (“Y1”) and 50% demand of stage two (“Y2”) for multistage cooling units.
6.3 Duty Cycles
Indoor temperature control is achieved by duty cycling the equipment when the
load value is less than 100% of the current stage of operation. Duty cycles do
not apply to variable/modulating region of VSPD outdoor units or modulating
furnaces. The duty cycle rate is dependent on the calculated load value.
The duty cycle chart below indicates the number of cycles at 50% load (i.e. LV
= 50).
6 CPH
2 CPH
1 Hour
As with all PI-based controls, the indoor temperature will fluctuate above and
below the user selected setpoint to maintain comfort in the space. Adjusting
the factory set CPH (Cycles per Hour) can affect how tight the 1050 Control
operates around the setpoint. The CPH can be adjusted in the Installer
Setup>Equipment Settings (2 6 CPH)
· Factory default for compressor operation is 3 CPH
· Factory default for indoor heat is 5 CPH
Effects of changing the cycle rates
Lower CPH results in longer run cycles with less cycling but the indoor
temperature may deviate above and below setpoint.
Higher CPH results in tighter indoor temperature control but shorter, more
frequent cycles.
6.4 Overshoot Clamp
The 1050 Control will enforce an “off cycle” anytime the 1050 Control
overshoots more than 2.5°F. Once the indoor temperature is within 0.75°F of
setpoint an “on cycle” is allowed dependent on load value and minimum off
times.

6.5 Stage Thresholds
The threshold to allow operation is a Load Value greater than 5 and operation
is always terminated with a Load Value less than 1.
Load Value also determines when additional stages of operation are requested.
To prevent rapid cycling between stages, a stage threshold is enforced. The
stage threshold is dependent on the applied system.

6.6 Stage Inhibits
When the stage threshold is exceeded, a stage inhibit is applied. The stage
inhibit calculates the rate of recovery over a 10-minute period and determines
if the next stage is required to meet the current demand. If the rate of
recovery is great enough, a new 10-minute inhibit is enabled. The 1050 Control
will not go to the next stage of operation until it determines that the
current stage cannot satisfy the current demand. Stage inhibits only apply
between compressor stages and compressor heat to indoor heat. Stage inhibits
do not apply to indoor heat stages.
Stage inhibits can be disabled in the 1050 Control Installer Setup>Comfort
Settings.

6.7 System Mode
The 1050 Control has (5) System Modes which can be selected: Heating, Cooling,
Off, Emergency Heat and Auto.
· Heating System will only operate in heating mode
· Cooling System will only operate in the cooling mode
· Off System will not operate in heating or cooling mode
· Emergency Heating System will operate the indoor heat source only (this is
only available when the outdoor unit type is a heat pump)
· Auto – The 1050 Control will determine which mode of operation based on the
following rules:
· Heating – Indoor temperature is equal or less than heating setpoint
· Cooling Indoor temperature is equal to or greater than cooling setpoint or
within 1°F of cooling setpoint
There is minimum deadband between heating and cooling setpoints of 3°F (4°F
when zoning is applied).
6.8 Quiet Mode (VSPD Systems Only)
Quiet Mode limits compressor operation (Heating and Cooling Mode) % Demand to
meet local sound requirements. There are two effective times that can be
adjusted. Day which starts are 9 AM and Night which which starts at 10 PM
which is required in certain jurisdictions.
The Quiet Mode feature is available on the 1050 comfort controls.
Charcteristics of Quiet Mode
· When active, the QM symbol will be displayed on the 1050 Home Screen.
· When enabled, Quiet Mode limits both heating and cooling modes.
· Quiet mode may be configured to only limit Day operation, only limit Night
operation, or limit Day and Night operation to different % demands.
· Night mode affects operation from 10 PM until 9 AM, at which point Day
settings for Quiet Mode take over.
· During heating mode, indoor supplemental heat is allowed if the system
cannot maintain space conditions while Quiet Mode is active.
· Local code may require auxiliary heat lockout to be configured.
NOTE: Quiet Mode is disabled by default in the homeowner system options. The
option to Disable or Enable Quiet Mode is always available to the homeowner.
This functionality is accessed from the Home Screen by pressing System Mode>
System Options>Enable on the Quiet Mode option. If Quiet Mode is enabled
without installer setup, Night operation allows only the minimum % Demand and
Day operation allows maximum % Demand. To optimize Quiet
XL 1050
Mode performance, the installing dealer must make the changes to the setup
found in the Quiet Mode Set-up document available online.
6.9 Fan Mode
The 1050 Control has three Fan Modes: · Auto Fan only runs with a call for
heating or cooling · On Fan runs continuous · Circ Fan runs a user
selected minimum amount of time each hour
6.10 Air Cleaner Mode
The 1050 Control has three Air Cleaner modes: · Auto Air cleaner operates
only with a call for fan operation · Quick Air cleaner will operate for
3-hours with blower at 100% · Allergy Air cleaner will operate for 24-hours
with blower at 100%
Note: If a communicating Air Cleaner is installed, the power level will be set
to High during Quick and Allergy Clean Modes.

7. Advanced Operation
7.1 Control Response Rate
Allows the user to select a set of higher proportional-integral control
constants to increase the responsiveness of the 1050 Control. Selecting “Fast”
will cause the 1050 Control to generate load value at a faster rate. Control
Response rate can be adjusted in Installer Setup>Comfort Settings.
7.2 Dehumidification
The 1050 Control utilizes the following methods for dehumidification:
· Air flow reduction (applies only to variable speed blowers) The 1050
Control can reduce the system air flow by 30% anytime the indoor RH is higher
than the cooling RH target. Air flow reduction is disallowed if the indoor
temperature is more than 2°F above the cooling setpoint. Dehumidification is
factory enabled in the Installer Setup>Comfort Settings.
All “Fan Off” delays are also defeated when dehumidification is enabled and
the indoor RH exceeds the cooling RH target.
· Overcooling [Disabled when zoning is applied] (applies to variable speed and
non-variable speed blowers) – If overcooling is enabled, the 1050 Control will
allow a 0.1°F of overcooling for each 1% of RH error. A maximum amount of
overcooling can be configured for 1°, 2° or 3°F.

configured in Installer Setup>Comfort settings.
· Smart Continuous Fan (applies to variable speed and non-variable speed
blowers) If enabled, continuous fan operation will be interrupted when
indoor RH exceeds desired cooling RH target. A humidity icon will be displayed
along with the fan icon to indicate that continuous fan operation has been
disabled due to high humidity conditions. Smart Continuous Fan will also
interrupt the fan circulate mode when indoor humidity exceeds the desired
cooling RH. This feature can be enabled in the Installer Settings>Comfort
Settings>Smart Continuous Fan settings.
7.3 Dehumidifier Operation
The 1050 Control has the ability to control a Whole-House Dehumidifier through
the normally open dry AUX Contacts on the optional Relay Panel. Control
options are:
· Stand Alone Operation Dehumidifier can operate independent from cooling
operation as long as the 1050 Control is in Cooling mode or Auto mode and the
last call was cooling. When applied with a zoning system, all dampers are
driven full open when the dehumidifier is operating without a call for
capacity.
If Stand Alone Operation is selected, the 1050 Control allows the user to
select whether the indoor fan operates with dehumidifier request.
For systems with variable speed blowers, the blower speed during a call for
dehumidification only will be the same as continuous fan speed
· With Active Call for Cooling Only Dehumidifier can only operate during an
active call for cooling.
All dehumidifier control options are located in the Installer
Setup>Accessories Settings.
7.4 Dual Fuel Operation
The 1050 Control can control a dual fuel system without the need of an
external dual fuel kit. An Outdoor Temperature Sensor must be installed and
enabled for Restricted Modes to be available. The 1050 Control options are:
· Non Restricted Mode The 1050 Control will determine which mode of heat
will operate to maintain comfort based on the calculated system load value.
With a load value in compressor heating range the heat pump will operate and
if the load value climbs to auxiliary heat range, the heat pump will cycle off
and the auxiliary heat source will cycle on. Once the load value falls below
the auxiliary heat range, the auxiliary heat will cycle off, and the heat pump
will cycle back on.
· Restricted Mode (compressor heat only) Once enabled an outdoor temperature
lockout can be set to disable compressor heating operation. When the outdoor
temperature falls below the compressor heat lockout the system will operate on
auxiliary heat source only. At any temperature above the compressor heat
lockout the system will operate the same as non-restricted mode, heat pump or
auxiliary heat would be allowed based on system load value. Once the
compressor heat is locked out, the outdoor temperature must rise at least 4°
above the compressor heat lockout setting before allowing compressor heat
again.

7.6 Humidifier Operation
The 1050 Control has the ability to control a humidifier. Humidification is
only enabled while in heating mode of operation. Control options are:
· RH Control When the indoor humidity is less than the heating target
relative humidity, a request for humidification is sent to the indoor unit.
· Frost Control The 1050 Control references the outdoor temperature and
structure integrity to offset the heating target relative humidity. This helps
to limit the risk of frost or condensation from forming on interior walls and
windows. A scale of 1 to 10 is provided based on the insulation properties and
expected leakage of the home (1=Leaky with poor insulation, 10=Very Tight with
good insulation). An outdoor temperature sensor must be connected and enabled
for frost control to be available.
Frost Control Structure Integrity Scale
1 2 3 4 5 6 7 8 9 10 Leaky, Poor Insulation Average Good Insulation, Tight
The 1050 Control can be setup to allow humidification anytime in heating mode
or only when actively heating. The airflow during Humidifier-only is factory
set to 100% but can be adjusted between 35%-100% (this requires a variable
speed indoor blower). All humidifier control options are located in the
Installer Setup>Accessories Settings. When zoning is applied, all dampers open
fully on a for humidification only.
7.7 Stage Inhibits
The 1050 Control utilizes a Stage Inhibit to limit equipment staging. This
inhibit can be defeated in the following two manners.
7.7.1 Aggressive Recovery
Greater than 2°Setpoint Change Disables stage inhibits in heating and cooling
mode anytime the setpoint is adjusted more than 2°F
7.7.2 Heating Aggressive Recovery
By Outdoor Temperature Disable stage inhibit in heating mode only when the
outdoor temperature falls below the selected outdoor temperature. Note: If
Aggressive Recovery is enabled, Heating Aggressive Recovery is disabled.
7.8 Ventilation Operation
The 1050 Control has the ability to control a Ventilation system through the
normally open dry AUX Contacts on the optional Relay Panel. The blower can be
interlocked on a call for ventilation. The blower speed during a call for
ventilation only will be the same as the continuous fan setting
22
for units with a variable speed indoor blower. When zoning is applied, all
dampers open fully on a call for ventilation only. The ventilation run time
per hour can be adjusted to meet ASHRAE 62.2 standards. A temperature override
can be set to prevent ventilation operation when the outdoor temperature
exceeds the minimum or maximum outdoor temperature selections. If outdoor
temperature overrides are enabled the user can select to accumulate the missed
ventilation run time. Options are below:
· Accumulate missed ventilation run time in 4 hour increments and make up when
the outdoor temperature is within the min/max settings.
· Accumulate missed ventilation run time in 24 hour increments and make up
when the outdoor temperature is within the min/max settings
· Accumulate missed ventilation run time in 4 hour increments and make up at
the end of 4 hour period.
· Accumulate missed ventilation run time in 24 hour increments and make up at
the end of 24 hour period.
All Ventilation control options are located in the Installer Setup>Accessories
Settings.
7.9 Warm Air Discharge
[Disabled when zoning is applied] Enabling Warm Air Discharge will reduce the
variable speed blower air flow by 20% when in compressor heating operation.
Warm Air Discharge only applies to compressor heating and is disabled when
hydronic, fossil fuel or electric heat (including supplemental heat) modes are
activated.Warm Air Discharge can be enabled in Installer Setup>Comfort
Settings.
7.10 Wet Heat (Hydronic) Operation
A hot water coil can be applied to either a variable speed or non-variable
speed indoor unit. The hot water coil can be the sole source of heat or used
as auxiliary heat when applied with a heat pump. When applied with a heat
pump, wet heat is considered auxiliary heat and will operate inconjunction
with heat pump heat. Switching the system mode to emergency heat would disable
the heat pump and cycle the wet heat only.
When using BK to control a variable speed air handler, the blower speed during
wet heat only heating will vary based on the system load value. The airflow
will range from 35% to 100% depending on the system load value. When applied
with a heat pump, the blower speed during heat pump and wet heat operation
will be the higher of the two air flows. When not using BK for variable speed
blower control, the air handler will determine air flow. There are separate
blower “On” and “Off” delays for wet heat in the 1050 Control.
The 1050 Control is designed to operate forced air systems and should not be
applied to non-forced air systems (radiant floors, radiators, etc…)
The hydronic heat blower delay options can be accessed by navigating to
Installer > Setup > Airflow Settings.

8. Zoning
8.1 Introduction
The 1050 Control is zoning capable with the ability to control single stage,
multi stage and variable speed equipment.
The 1050 integrates modulating damper control within system operation without
jeopardizing system reliability. The 1050 Control manages excess air by
relieving excess air flow into non-calling zones eliminating the need for a
bypass damper or position stops in the supply dampers
**For optimum performance and comfort, the number of zones should be limited
based on the type of system installed.

8.2 Zoning Requirements
· 1050 Control · One Zone Panel is required for up to 4 zones, an
optional Zone Expander is needed if more than 4 zones are installed · Either a
communicating or non-communicating zone sensor for each zone
XL 1050
· Power open/power closed fully modulating dampers with a damper travel time
between 15 60 seconds…60 seconds is the default setting
· Trane or American Standard manufactured indoor unit with a variable speed
blower (branded Geothermal package units and oil furnaces are not supported)
· Field supplied 24-volt transformer (transformer should be sized to
accommodate all loads connected to Zone Panel)
· Relay Panel would be required if non-communicating HVAC equipment is
installed
8.3 Operation
When zoning is applied, load value still controls system operation but now
each zone will report its own load value.
With zoning each zone will report its own operating parameters:
OPERATING PARAMETER
DESCRIPTION
Requested System Mode
Heating/Cooling/Off
Zone Load Value
Capacity required to reach each zone’s requested set point
Zone Size
Percentage of total system air flow each zone can handle
Voting Status
1. Voting zones determine the System Mode and voting zones can request system
operation
2. Non-voting zones are only active when a voting zone has requested system
operation
Fan Request
1. Each zone has fan mode option of On or Auto
2. System fan mode determined by last selected zone fan mode
3. When the Fan Mode selected is ON and the system is currently not
delivering capacity, all zones dampers are positioned full open
The 1050 Control uses the parameters above to determine:
8.3.1 Mode of operation
The mode of operation for zoned systems is determined by the following:
1. Sum the weighted load value (zone size x zone LV) of all active voting
zones (zones with LV > 0) in the same mode of operation
2. The higher of the summed weighted LV’s would determine the current mode of
operation
3. Once operating in any mode, there’s a 15 minute time requirement before
allowing a mode change
18-HD80D1-6F-EN

Installation Guide
Example for determining System Mode:

Heating
ZONE 4
50 (htg) .65 32.5
8.3.2 Capacity Request (System LV)
System LV is used to determine how much capacity will be requested. System LV
is determined by the zone with largest load value in the current mode of
operation. See Section 6.2 Load Value for heating and cooling tables for
additional information regarding the load value ranges for different systems.
Example for determining System Load Value:
Zone LV System LV
ZONE 1
60 (clg)
ZONE 2 ZONE 3
50 (clg) 80 (clg) 80
ZONE 4
50 (clg)
For VSPD outdoor units and modulating furnaces the System LV is scaled:
· SysLV 80 = Raw LV x 1.25 · SysLV > 80 = (Raw LV x .8333) + 33.33 · Zone LV
is not scaled, only System LV
Example for determining Scaled System Load Value:
ZONE 1 ZONE 2 ZONE 3 ZONE 4
Zone LV
60 (clg) 50 (clg) 80 (clg) 50 (clg)
System LV Scaled System LV
80 System LV (80) x 1.25 = 100
When zoning is applied the System LV may be inhibited for the following
reasons:
· The sum of the calling zones is less than or equal to the current stage of
capacity (compressor and gas furnace operation only)
· (VSPD systems only) Auxiliary Heat Clamp is enabled and the sum of the
calling zones is less than or equal to the clamp setting (Installer
Settings>Clamp LV for Auxiliary Heat)
For VSPD systems the speed of the compressor will be limited based on the air
flow capacity of the calling zones. Oil return or other protection algorithms
may override this clamp
24
8.3.3 Damper position
The position of the modulating dampers is determined by the amount of capacity
each zone is requesting.
The damper position for each same mode calling zone follows the calculation
below:
· Zone LV/ System LV = damper position
The minimum opening position is always 25% to reduce air whistling from a
partially opened damper
Zones in the opposite or “off” mode are closed unless the system has
calculated excess air.
Example of how Damper Positions are calculated for nonVSPD and VSPD systems:
NON-VSPD
Zone LV System LV Damper Position
ZONE 1 ZONE 2 ZONE 3 ZONE 4
60 (clg)
50 (clg) 40 (clg) 60
50 (clg)
100%
83%
67%
83%
For non-VSPD systems one damper will always be full open on a call for capacity and the other dampers will modulate based on their load value.
VSPD
ZONE 1 ZONE 2 ZONE 3 ZONE 4
Zone LV
60 (clg) 50 (clg) 40 (clg) 50 (clg)
System LV

Scaled System LV
Sytem LV (60) x 1.25 = 75
Damper Position
80%
67%
53%
67%
For VSPD cooling or compressor heating the scaling of the system load value
will result in the dampers being in a less open position than non-VSPD
systems. This partial restriction helps maintain static pressure for improved
air flow distribution.
8.3.4 Excess Air Management
The 1050 Control manages excess air without the need for bypass dampers, dump
zones or position stops in the supply dampers.
The first method of managing excess air is to eliminate or reduce the excess
through equipment stage control and air flow modulation
· Equipment Stage Control For systems with capacity control, the 1050
Control will limit the capacity request based on the sum of the calling zones
size…insert chart
· For systems with capacity control, if the sum of the calling zones sizes are
less than or equal to the current stage of capacity the system load value will
be inhibited disallowing the next stage of operation
· For VSPD systems, the speed of the compressor will be limited based on air
flow capabilities of the calling zones. This inhibit may be overridden during
oil return mode or if the sum of the calling zones is less than the minimum
compressor speed at the current outdoor conditions.

If the 1050 Control still calculates excess air, then the excess will be
relieved following the rules below:
· Relief Strategy 1
Divide the excess air evenly between the zones which are calling but their
dampers are not 100% open
· Relief Strategy 2
Divide the remaining excess air evenly between the zones which are in the same
calling mode but have zero load value (zones in the “OFF” mode are considered
same calling mode zones)
· Relief Strategy 3
Divide the remaining excess air evenly between the zones which are in the
opposite mode regardless of load value
Note – The minimum damper position when a zone is relieving is 25%.
XL 1050
Relief Strategy The relief strategy employed by the 1050 successfully manages
excess air without affecting the efficiency or reliability of the applied
heating/cooling system. Zone(s) may overshoot their setpoint if the system is
not applied properly. Common application mistakes which cause zone(s) to
overshoot: 1. Too many zones applied for the equipment selected 2.

9.3.2 Summary Table
The 1050 Control has a Summary Table which lists all the communicating devices
that have been discovered. In addition to viewing the status of each
communicating device, the Summary Table can be used to remove “offline”
devices. The screen is made up of three fields:
· Device Information: Lists the device name and model/ serial number
· Enabled: Identifies whether the device has been enabled
· Status: Identifies whether the device is currently reporting on the bus
(Only “Offline” devices can be removed)
The Enabled and Status field can be used to troubleshooting/ informational
purposes:
· Enabled + Online: Device has been enabled and is currently reporting on bus
· Enable + Offline: Device has been enabled but is not reporting (Err.126.00
will typically be triggered during this condition).
· Disabled + Online: Device has not been enabled but is reporting (verify
device has been configured in the installer settings).
· Disabled + Offline: Device has not been enabled and is currently not
reporting.
