Introduction
Read this manual thoroughly before operating or servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal
safety and the proper operation of this machine depend upon the strict
observance of these precautions.
The three types of advisories are defined as follows:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, could
result in minor or moderate injury. It could
also be used to alert against unsafe
practices.
NOTICE
Indicates a situation that could result in equipment or property-damage only accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the
earth’s naturally occurring stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified chemicals that may affect
the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon
(CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs).
Not all refrigerants containing these compounds have the same potential impact
to the environment. Trane advocates the responsible handling of all
refrigerants.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the
environment, our customers, and the air conditioning industry. All technicians
who handle refrigerants must be certified according to local rules. For the
USA, the Federal Clean Air Act (Section 608) sets forth the requirements for
handling, reclaiming, recovering and recycling of certain refrigerants and the
equipment that is used in these service procedures. In addition, some states
or municipalities may have additional requirements that must also be adhered
to for responsible management of refrigerants. Know the applicable laws and
follow them.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field
wiring MUST be performed by qualified personnel. Improperly installed and
grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these
hazards, you MUST follow requirements for field wiring installation and
grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death
or serious injury. Technicians, in order to protect themselves from potential
electrical, mechanical, and chemical hazards, MUST follow precautions in this
manual and on the tags, stickers, and labels, as well as the instructions
below:
· Before installing/servicing this unit, technicians MUST put on all PPE
required for the work being undertaken (Examples; cut resistant
gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
· When working with or around hazardous chemicals, ALWAYS refer to the
appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and
Labeling of Chemicals) guidelines for information on allowable personal
exposure levels, proper respiratory protection and handling instructions.
· If there is a risk of energized electrical contact, arc, or flash,
technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other
country-specific requirements for arc flash protection, PRIOR to servicing the
unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT
PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND

Economizer Controller
NOTICE Electrostatic Discharge!
Electrostatic discharge can short equipment circuitry. Ensure that you are
properly grounded before handling sensitive electronic equipment.
Notes:
· At power up or after a power outage or brownout (or if power goes below 18
Vac), the controller begins a 5 minute power up delay before enabling
mechanical cooling. Power must be above 18 Vac for the delay to become
functional.
· The controller will be in Setup mode for the first 60 minutes after powered.
If a sensor for outside air or one of the Sylk Bus devices (sensor or
actuator) is disconnected during the set up mode, the controller will not
alarm that failure. The mixed air temperature sensor is a system critical
sensor; if it is removed during the set up mode the controller will alarm.
After 60 minutes the controller will change to Operation mode and all
components removed or failed will alarm in the operation mode.
· The terminals on MAT, OAT and S-BUS sensors are polarity insensitive.
Controller User Interface and Keypad
The user interface consists of an LCD display and a 4-button keypad on the
front of the economizer module. The LCD is a 16 character by 2 line dot matrix
display.

Initiation of Operating Modes
The JADE controller is able to initiate the following modes: Compressor,
Economizer, Fans, Heating System, and Cooling System. Compressor mode is
initiated by either the OAT going above the DRYBLB SET setting or by the
thermostat initiating a call to cool when the damper is at 100 percent open.
The Economizer mode is controlled by the MAT getting above the MAT SET setting
while the OAT is below the DRYBLB SET setting. While the fans are not
controlled by the controller, the Fan mode is dependent on what state the
system is in (OCC or Y1 states will cause the damper to go to a LOW fan speed
damper setting, while W state will cause the controller to open the damper to
the HIGH fan speed damper setting). The Heating System mode requires an input
to the AUX2-1 terminal from the thermostat, and the Cooling System mode
requires an input to the Y1 IN terminals from the thermostat.
Economizer Setup and Configuration (Field and Factory Installed Option)
Before being placed into service the controller must be setup and configured
for the installed system. Important: During setup, the economizer controller
is live
at all times. 1. Using the keypad on the controller scroll through the
Setpoints, System Setup, and Advanced Setup menus and verify or set/change the
parameters. See Table 4, p. 12. 2. Install front filter access panel back on
to unit and secure with previous screws. Notes: · The W (heating mode) is not
controlled by the controller but it requires the status to know where to
position the outside air damper for minimum position for the fan speed. · All
setpoints and advanced settings are restored after any power loss or
interruption.
ACC-SVN205E-EN
Enthalpy Settings
NOTICE
Electrostatic Discharge!
Electrostatic discharge can short equipment circuitry. Ensure that you are
properly grounded before handling sensitive electronic equipment.
When the outside air temperature, enthalpy, and dew point are below the
respective setpoints, the outdoor air can be used for economizing. See Figure
14, p. 18.
Note: The controller calculates the enthalpy and dew point using the outside
air temperature and humidity input from the outside air sensor.
1. There are 5 boundaries (setpoints ES1 through ES5), which are defined by
dry bulb temperature, enthalpy and dew point. See Table 9, p. 17.
2. When conditions are below the selected boundary, the economizer sets the
economizing mode to YES and economizing is available. When conditions are
above the selected boundary, the conditions are not good to economize and the
mode is set to NO.
Note: When using the enthalpy (Sylk Bus) sensors, there will be a slight delay
while the controller and the sensor communicate. Analog sensors do not
communicate on the Sylk Bus and output a 20k ohm signal to the controller with
an instantaneous response time.

To configure the LLE controller, set EXH1 SET in the SETPOINTS menu.
CO2 Sensor
This optional sensor can be added for Demand Control Ventilation (DCV)
functionality. To configure the JADE controller, set the following parameters:
SETPOINTS Menu: DCV SET = desired CO2 ppm to start DCV VENTMAX = desired
maximum position w/DCV and occupied status VENTMIN = desired minimum position
w/DCV and occupied status ADVANCED SETUP Menu: CO2 ZERO = set to detectors
start level CO2 SPAN = detector’s max level minus start level Attach the
sensor to the CO2 and R terminals (at customer connections). Note: When using
any 0 to 10 Vdc CO2 sensor with the JADE
set CO2 ZERO to 400 ppm and the CO2 SPAN to 1600 ppm in the ADVANCED SETUP
menu.
ES5 ES4 ES3 ES2 ES1 HL M32286
Occupancy Sensor
A customer-supplied occupancy sensor can also be added to provide damper
control based on occupied/unoccupied conditions. To configure the JADE
controller, set:
SYSTEM SETUP menu: OCC = INPUT
Attach the occupancy sensor to the OCC SENSOR wire and R terminal (at customer
connections). The occupancy sensor must utilize a normally open contact for
proper operation.
If an occupancy sensor is not used, another option to controlling occupied and
unoccupied status is to use the G input (fan is running). Connect the G input
to the OCC SENSOR wire (at customer connections). The controller will then
operate in the occupied mode every time the indoor fan is running.
