Voltage Ports
NOTE: The communicating thermostat is able to search and identify the indoor and outdoor units when power is applied to the system. Refer to the communicating thermostat’s installation instructions for more information.
Connect low voltage communication wires (1, 2) to low voltage pigtail provided.
COMMUNICATION WIRING
NOTE: A terminal block is attached with the control board to make wiring connections for the thermostat. Connect the wire to the terminal block. (1.5 – 3.0 ton only) A removable plug connector is provided with the control board to make thermostat wire connections. Remove the plug, connect the wires to the plug, and then replace. (3.5 – 5.0 ton only) It is strongly recommended that you do not connect more than two wires into a single terminal in the field because there is a risk of the wires becoming loose, which may result in communication error. Refer to Troubleshooting Tables for error codes.
To wire the system components, it is strongly recommended to use the same type and same gauge for the wires prepared in the field. (For best results, use 18 AWG.) However, communications reliability may be improved by using a high quality,

ATTENTION INSTALLER IMPORTANT NOTICE!
Please read carefully before installing this unit.
· Low voltage terminal C from indoor unit must connect to low voltage terminal C on thermostat and low voltage terminal R from indoor unit must connect to low voltage terminal R on thermostat. Verify wires are not reversed. (Note: The order of the terminals of the indoor unit and your thermostat may be different system wiring.)
· Do not attach any wires to the R & C Terminals on the Outdoor Unit, as they are not needed for inverter unit.
· Data line terminal #1 from outdoor unit must connect to terminal #1 on indoor unit and thermostat and data line terminal #2 from outdoor unit must connect to terminal #2 on indoor unit and thermostat. Verify wires
are not reversed.

STEP 1. CALCULATE REFRIGERANT CHARGE BASED ON LINE SET LENGTH
The outdoor unit is shipped with a predetermined factory charge level as shown below. Please follow below step. Refer to the following page for the equivalent length of the elbow fittings.

Total Refrigerant Charge (A)

=

Factory Charge (B)*

Additional Charge for line set (C)

(A) to (C) parameters are shown in below table.

The following table shows refrigerant amount for every 5 feet of line. Choose connected indoor coil type, Liquid/Suction pipe diameter and line set length. Calculate charge amount by linear approximation in between line set length mentioned below table.

• Factory Charge (B) may differ from the value specified on the unit name plate. In that case, calculate the Additional Charge (C) as to keep the Total Refrigerant Charge (A) indicated in the table.

STEP 2. CHARGE BY LINESET LENGTH

ADDITIONAL CHARGE ADJUSTING PROCEDURE

CAUTION
enSure ValVeS are open and addItIonal charge IS added per chart Before applyIng poWer.
Charge additional refrigerant calculated by the equation & table in Step 1.
After the refrigerant charge has bled into the indoor unit, open the liquid service valve. The service valve cap is the secondary seal for the valves and must be properly tightened to prevent leaks. Make sure cap is clean and apply refrigerant oil to threads and sealing surface on inside of cap. Tighten cap finger-tight and then tighten additional 1/6 of a turn to properly seat the sealing surfaces.
Break vacuum by fully opening liquid and suction base valve.
NOTE: 1.5 – 3.0 ton have front seating valves. 3.5 – 5.0 ton have front / back seating valve. Refer detail function on page 17. It is not necessary to force the stem tightly against the rolled lip.
STEP 3. SYSTEM START-UP TEST
For a detailed procedure, please visit the Amana HVAC website at https://www .amana-hac.com/products/controls/ touchscreen-thermostats
NOTICE
on InItIal poWer Startup, the outdoor unIt WIll dISplay code e11, SIgnalIng that InItIal SyStem teSt muSt Be run. folloW the amana communIcatIng thermoStat Setup Screen to enter applIcatIon-unIque InformatIon. See amana communIcatIng thermoStat manual for detaIled InformatIon.
A system test is now required to check the equipment settings and functionality. Once selected, it checks the equipment for approximately 10 – 15 minutes. System test may exceed 15 minutes if there is an error. Refer to the Troubleshooting section, if error code appears.
Before starting the SYSTEM TEST, turn off the electric heater or gas furnace.
NOTE: Ensure the thermostat is in OFF. Choose “OFF” before “CHARGE MODE”.

STEP 4. MEASURE SUBCOOLING TO VERIFY PROPER CHARGE
Set thermoStat to charge mode
If required additional charging amount cannot be charged to the system without operation, then use this “CHARGE MODE”.
When adjusting “Sub cooling”, use this “CHARGE MODE”.
CHARGE MODE allows for charging of the system. System operates for a duration of approximately two hours while the equipment runs at full capacity. After two hours, the CHARGE MODE ends and the system resumes normal thermostat operation.
Before starting the CHARGE MODE, turn off the electric heater and finish SYSTEM START-UP TEST.
NOTE: Charging equipment must use dedicated PVE oil gauges and hoses.
1. Purge gauge lines. 2. Connect service gauge manifold to liquid base valve
service ports. 3. Convert the liquid pressure to temperature using a
temperature/pressure chart. 4. Temporarily install a thermometer on the liquid line at
the liquid line service valve. Ensure the thermometer makes adequate contact and is insulated for best possible readings. 5. Subtract the liquid line temperature from the converted liquid pressure to determine subcooling. 6. Before starting the subcooling adjustment, make sure the outdoor ambient temperature is in the range shown in charging table and the unit is operating at 100% capacity. When the unit is ready for charging, the seven segment display will show “cha” and current subcooling value alternately. When the outdoor ambient temperature is 65°F-105°F, the seven segment display will show current subcooling value. 7. If the system subcooling is not within the range as shown in the charging table, adjust subcooling according to the following procedure. · If subcooling is low, add charge to adjust the sub-
cooling as specified in the following table. · If subcooling is high, remove charge to adjust the
subcooling as specified in the following table.
NOTE: The seven segment display can keep flashing “cha” in charge mode when the system is not in condition. Then subcool adjustment is not available. Please complete charging following STEP1 and 2.
NOTE: To achieve rated performance, measure subcooling using a pressure gauge and temperature sensor.

SYSTEM OPERATION
SyStem adVanced featureS
This system permits access to additional system information, advanced set-up features, and advanced diagnostic/ troubleshooting features. These advanced features are organized into a menu structure.
For detailed functions and menu layout, please visit the Amana Smart Thermostat website at https://www.amana- hac.com/products/controls/touchscreenthermostats
coolIng BooSt mode
COOLING BOOST MODE enables the system to operate at increased compressor speeds in cooling mode to satisfy unusual high loads. COOLING BOOST MODE is initiated by an outdoor temperature sensor located in the outdoor unit. Please note that outdoor equipment operational sound levels may increase while the equipment is running in COOLING BOOST MODE since compressor speed higher than normal operation is allowed.
NOTE: COOLING BOOST MODE is ON by default and is activated when the outdoor temperature reaches 100°F. COOLING BOOST MODE can be disabled and enabled and the activation temperature adjusted in “COOLING BOOST MODE Temperature”
heatIng BooSt mode (hp model only)
HEATING BOOST MODE enables the system to operate at increased compressor speed while in heating mode, regardless of outdoor ambient temperature. However, maximum compressor speeds only appear in low ambient temperature operation if HEATING BOOST MODE is disabled.
Backup defroSt (defroSt heat) mode (hp model only)
This mode enables the system to select heating operation during defrost. When this mode is ON, 2nd heating source (Electric Heater or Gas Furnace) is turned on during defrost. This mode is initiated by an outdoor temperature sensor located in the outdoor unit. This mode is activated when the outdoor temperature reaches set point. Also “Always ON” and “OFF” are available.
maxImum defroSt InterVal
This setting enables the system to change timer defrost interval. In the case system needs to have defrost operation more frequently, defrost interval can be changed. The initial setting is 120 min.

dehumIdIfIcatIon
The thermostat reads the indoor humidity level from the field setting menu and allows the user to set a dehumidification target based on these settings. The thermostat controls the humidity level of the conditioned space using the cooling system. Dehumidification is engaged whenever a cooling demand is present and structural humidity levels are above the target level. When this condition exists the circulating fan output is reduced, increasing system run time, over cooling the evaporator coil and ultimately removing more humidity from the structure than if only in cooling mode.
For effective dehumidification operation: · Please revise it to read ensure Dehumidification is NOT
set to “OFF.” · If “STD”, system run lower CFM than normal cooling
mode. · In addition, the system can have Enhanced
Dehumidification operation in setting “A”, “B” or “C” based on dehumidification demand.
In the Enhanced Dehumidification the indoor airflow is lower than Standard Dehumidification. Setting “A” allows for the widest compressor range with lower cfm than standard dehumidification. Setting “B” limits compressor operation range and keeps high dehumidification capacity. In setting “C” the system runs fixed at 100% compressor and airflow. See Figure 1.
· Verify the cooling airflow profile (cool profiles) is set to “Profile D”.
· For additional dehumidification control, airflow settings are field adjustable and can be fine-tuned to a value that is comfortable for the application from a range of Cool Airflow Trim.
NOTE: In high humidity environments, sweating on supply ducts, cased coils or air handler cabinets can become an issue in Enhanced Dehumidification operation. It is recomended covering them with 2″ fiberglass insulation for these installations.

quIet mode
QUIET MODE enables the system to operate at decreased compressor and fan speeds to satisfy quiet driving.
QUIET MODE is initiated by user’s setting (“ON” or “OFF”. Default is “OFF”).
NOTE: “NOISE DOWN LEVEL” is initiated by user’s setting.
(“LEVEL” “1”, “2” or “3”. Default is “LEVEL” “2”. “LEVEL” “3” is the most quiet.)
If during operation the capacity demand is high, then the quiet mode function will be temporary off by capacity priority function to return the room temperature to the set point. (Default capacity priority setting is ON)
Capacity priority setting = OFF Capacity priority setting = ON

zonIng mode
ZONING MODE is recommended to use when the zoning controller and dampers are installed. This mode allows the system to run with lower indoor air flow comparing with normal operation when the cool or heat demand is low. The ZONING MODE is disabled in factory default setting. It can be activated through the thermostat user menu and 7-segment display.
cIrculatIon SelectIon
This setting can be used to switch circulation factor ON and OFF to avoid automatically increasing the indoor CFM by circulation control.
When it is ON, the system may increase indoor CFM to circulate indoor air in the event the outdoor control detected low evaporative temperature.
When it is OFF, even if the outdoor control detects low evaporative temperature, it will NOT increase CFM.
ON is reccomended generally, but when a zoning controller is connected, it is recommended to be OFF on this setting to avoid unexpected high static pressure.
Set thermoStat to adjuSt maxImum compreSSor Speed
Maximum compressor speed at which the outdoor unit will operate can be changed using thermostat. Maximum compressor speed can be changed to get the required capacity or efficiency. Once the maximum speed is set, the system operates between the set maximum speed and default low speed.

29

Set thermoStat to adjuSt Indoor aIr cfm trIm
User can change the airflow trim at high, intermediate and low compressor speed.
Select:
Cool Airflow trim High: -15% ~ +15% Cool Airflow trim Intermediate: -15% ~ Full Cool Airflow trim Low: -15% ~ Full Heat Airflow trim High: -15% ~ +15% Heat Airflow trim Intermediate: -15% ~ +15% Heat Airflow trim Low: -15% ~ +15%
Under each trim setting, the airflow can be increased or decreased by a certain percentage.

• The Inverter system uses lower compressor speed and lower indoor unit CFM to optimize system performance. To obtain 100% CFM for home circulation, use full Trim setting instead of Int/Low speed. This is recommended for applications with unusual cold return temperatures such as basements.
  NOTE: Trim settings of the following combinations are restricted.

TROUBLESHOOTING
netWork trouBleShootIng
If a network communication error code has occurred, use the following steps to help troubleshoot the system. (For network communication error codes, refer to the table below and the tables of error codes for outdoor unit and indoor unit.)
After any wiring changes have been made or DS1 dip switches on the outdoor unit control board have been changed, apply power to the system and see if the error codes have cleared.
1. Confirm low voltage wiring is correct per installation instructions. Check for miswiring. (i.e. Terminal 1 and 2 is reversed.)
NOTE: A removable plug connector is provided with the control to make thermostat wire connections (3.5 – 5.0 ton only). This plug may be removed, wire connections made to the plug, and replaced. It is strongly recommended that you do not connect more than two wires into a single terminal in the field because there is a risk of the wires becoming loose, which may result in intermittent operation.

2. Check wires for damage. (i.e. Broken wire at terminal, broken inside wire nuts or damaged cable betwee nunits.)
3. Perform continuity check on wires to make sure cable is OK. Replace the cable if necessary
4. Change both dip switches of DS1 on the outdoor unit control board to the opposite position. See image below.

OUTDOOR UNIT HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS

SplIt SyStemS

We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer.

replace or clean fIlter
IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your air handler, in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your outdoor unit can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month.When they are dirty, replace or clean as required. Disposable type filters should be replaced. Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and nonelectronic types. These filters can do a better job of catching small airborne particles.
compreSSor
The compressor motor is hermetically sealed and does not require additional oiling.
motorS
Indoor and outdoor fan motors are permanently lubricated and do not require additional oiling.

clean outSIde coIl (qualIfIed SerVIcer only)
WARNING
HIGH VOLTAGE!
dISconnect all poWer Before SerVIcIng. multIple poWer SourceS may Be preSent. faIlure to do So may cauSe property damage, perSonal Injury or death.
Air must be able to flow through the outdoor unit of your comfort system. Do not construct a fence near the unit or build a deck or patio over the unit without first discussing your plans with your dealer or other qualified servicer. Restricted airflow could lead to poor operation and/or severe equipment damage.
Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or debris could also restrict the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could easily puncture the tubing in the coil. Even a small hole in the tubing could eventually cause a large loss of refrigerant. Loss of refrigerant can cause poor operation and/or severe equipment damage.
Do not use a outdoor unit cover to “protect” the outdoor unit. Outdoor unit fan may sometime start running regardless of demand from thermostat for system reliability reason.

Before callIng your SerVIcer

· Check the thermostat to confirm that it is properly set. · Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compressor operation for awhile, and then reset automatically. Also, some power companies will install devices which shut off outdoor units for several minutes on hot days. If you wait several minutes, the unit may begin operation on its own.
CAUTION
to aVoId the rISk of equIpment damage or fIre, InStall the Same amperage Breaker or fuSe aS you are replacIng. If the cIrcuIt Breaker or fuSe Should open agaIn WIthIn thIrty dayS, contact a qualIfIed SerVIcer to correct the proBlem. If you repeatedly reSet the Breaker or replace the fuSe WIthout haVIng the proBlem corrected, you run the rISk of SeVere equIpment damage.

· Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.
· Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.
· Check for obstructions on the outdoor unit. Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.
· Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains or furniture).
· Check the filter. If it is dirty, clean or replace it. · Listen for any unusual noise(s), other than normal oper-
ating noise, that might be coming from the outdoor unit. If you hear unusual noise(s) coming from the unit, call a qualified servicer.
