1. Turn off power to the heating and cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. To remove cover, insert and twist a coin or screwdriver in the slots on top of the thermostat.
3. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the wire opening in the base of the thermostat).
4.  Mark the placement of the mounting holes.
5. Set thermostat base and cover away from working area.
6. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
7. Use a hammer to tap supplied anchors in mounting holes.
8. Align thermostat base with mounting holes and feed the control wires through wire opening.
9. Use supplied screws to mount thermostat base to wall.
10. Insert stripped, labeled wires in matching wire terminals. See “Wiring Diagrams” section of this manual.
    CAUTION!: Be sure exposed portion of wires does not touch other wires.
11. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.
12. Seal hole for wires behind thermostat with non-flammable insulation or putty.
13. Replace cover on thermostat by snapping it in place.
14. Turn on power to the system at the main service panel.

1. Slide the Mode switch to the OFF position.
2. Remove the cover of the thermostat by gently pulling on one of the corners.
3. Simultaneously hold the LEFT & RIGHT buttons in for 2 seconds while the Amana® 2246003 is in OFF mode.
4. Press the down or up button to change settings within each screen.
5. Press the RIGHT button to advance to the next screen.
   Note: The LEFT button will return you to the previous screen.
6. To exit configuration mode, slide the Mode switch to Heat or Cool.

Configuration Mode Settings
The setup screens for Configuration Mode are as follows:

1. Temperature Scale (F or C) – Choose Fahrenheit or Celsius.
   Press the down or up button to select.
   Press the RIGHT button to advance to the next screen.
2. Heating System
   • HSo – Heat pump, cool active reversing valve
   • HSb – Heat pump, heat active reversing valve
   • HSE – Electric heat system
3. Temperature Differential – Stage 1 – (1°F to 5°F) (0.5°C to 2.5°C)
   • Set the number of degrees between your “setpoint” temperature and your “turn on” temperature for first stage.
   • Press the down or up button to set differential value.
   • Press the RIGHT button to advance to the next screen.
4. Temperature Differential – Stage 2 – (1°F to 5°F) (0.5°C to 2.5°C) (shows only for HP)
   • Set the number of degrees between when stage 1 turns on and stage 2 turns on.
   • Press the down or up button to set differential value.
   • Press the RIGHT button to advance to the next screen.
5. Staged Off Outputs (shows only for HP)
   • Select whether the outputs for heating and cooling are staged off independently or are satisfied simultaneously.
   • 1 = Economy Mode – Outputs are staged on and off in accordance with set point and differential.
   • 0 = Comfort Mode – Outputs are staged on and and all stages cycle off simultaneously when set point is satisfied.
   • Press the down or up button to select.
   • Press the RIGHT button to advance to the next screen.
6. Maximum Heat Setpoint (45°F to 90°F) (7.0°C to 32.0°C)

Starting the Thermostat
CAUTION!: Do not use air conditioning when the outdoor temperature is below 50 degrees. This can damage your air conditioning system and cause personal injuries.

1. Move the High/Auto/Low switch to the Auto position.
2. Move the Cool/Off/Heat switch to Heat or Cool, depending on the season.

Testing the Thermostat

Once the thermostat is installed, it should be thoroughly tested.
CAUTION!: Do not energize the air conditioning system when the outdoor temperature is below 50 degrees. It can result in equipment damage or personal injury.

Cool Test

1. Slide Mode switch to Cool mode.
2. Adjust set temperature so it is 5 degrees below room temperature.
3. Air conditioning should come on within a few seconds.
4. Adjust the set temperature 2 degrees above the room temperature and the A/C should turn off.
   There may be a fan delay on your system.
   Note: There is a four-minute time delay to protect the compressor after it turns off. To temporarily bypass the four-minute delay, slide the Mode switch to OFF for 2 seconds and then back to Cool.

Heat Test

1. Slide Mode switch to Heat mode.
2. Adjust the set temperature so it is 5 degrees above the room temperature.
3. Heat should come on within a few seconds.
4. Adjust the set temperature so it is 2 degrees below the room temperature and the heat should turn off. There may be a fan delay on your system.
   Note: For Heat pumps, there is a four-minute time delay to protect the compressor after it turns off. To temporarily bypass the four-minute delay, slide the Mode switch to OFF for 2 seconds and then back to Heat.

Fan Test

1. Slide Fan switch to High position.
2. Indoor fan turns on in high speed.
3. Slide Fan switch to Low position.
4. Indoor fan turns on in low speed.
5. Slide Fan switch to Auto position.
6. Indoor fan turns off.

Mode of Operation

The Amana® 2246003 is a thermostat for 24 VAC systems.

Heat Pump Operation
The thermostat activates the heat pump when the room temperature is below the heat set temperature (by the differential temperature). Auxiliary heat will be activated if the room temperature continues to drop. The heat outputs are staged off (configurable, setting 5) as the room temperature increases. The thermostat will not let the compressor come on for four minutes after it turns off. This protects your compressor.

Electric Heat Operation
The thermostat activated the electric heat when the room temperature is below the heat set temperature (by the differential temperature). The heat is turned off when the room temperature raises to one degree above the heat set point temperature. When the room temperature is greater than the cool set temperature (by the differential temperature), the cooling device is activated. The thermostat will not let the compressor come on for four minutes after it turns off. This protects your compressor. The Amana® 2246003 has the following operating modes: Cool, Off, Heat. In OFF mode, the thermostat will not turn on heating or cooling devices. In the Heat mode, the thermostat controls the heating system. In the Cool mode, the thermostat controls the cooling system. The indoor fan can be turned on in all operating modes using the Fan switch.

• Set fan to HIGH: for continuous high-speed operation
• Set fan to LOW: for continuous low-speed operation
• Set fan to AUTO: for low-speed fan operation only during a heat or cool cycle

Troubleshooting

Symptom	Remedy
No display	Check for 24 VAC at thermostat; display is blank when 24 VAC is not present
System fan does not come on properly	Verify wiring is correct
Thermostat turns on and off too frequently	Adjust temperature differential (see “Temperature Differential,” Stage 1, Step 3)
Fan runs continuously	Check fan Low/Auto/HIgh switch. Low or High position runs indoor fan continuously
Room temperature is not correct	Verify wall hole is plugged with putty or insulation; calibrate thermostat (see “Configuration,” Step 8)
ROOM displays	Room temperature offset is not zero (see “Configuration,” Step 8)
Auxiliary heat not on soon enough	Adjust differential for 2nd stage heating if required (see Configuration, Steps 3 & 4)
Problem not listed above	Press the Reset button once; display will be refreshed
