To Install Thermostat

ELECTRICAL SHOCK HAZARD: Turn off power at the main service panel by removing the fuse or switching the appropriate circuit breaker to the OFF position before removing the existing thermostat.

IMPORTANT: Thermostat installation must conform to local and national building and electrical codes and ordinances.
Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.

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, pull gently at the seam at the top.
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 slit in thermal intrusion barrier and into wire opening.
9. Use supplied screws to mount thermostat base to wall.
10. Insert stripped, labeled wires in matching wire terminals.
    • 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. Turn on power to the system at the main service panel.
13. Configure thermostat to match the type of system you have.
14. Replace cover on thermostat by snapping it in place.
15. Test thermostat operation as described in “Testing the Thermostat”.

Mode of Operation

The Amana® 2246007 is an auto changeover, 2-stage heat, 2-stage cool thermostat. It functions with air conditioning, heat pumps, gas, oil or electric heat systems. An outdoor sensor can be used to monitor the outdoor temperature. The thermostat activates the heating appliance when the room temperature is below the set heat temperature (by the differential temperature). The Amana® 2246007 will stop outputting when the call for heat has been satisfied. With heat pumps, the thermostat will not let the compressor come on for 4 minutes after it turns off. This protects your compressor.

When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling device is activated. The Amana® 2246007 will stop outputting when the call for cooling is satisfied. The thermostat will not let the compressor come on for 4 minutes after it turns off. This protects your compressor. The Amana® 2246007 has four possible operating modes: OFF, Heat, Cool, and Heat & Cool mode. In off mode, the thermostat will not turn on heating or cooling devices. The manual fan can be turned on in all operating modes using the fan button. In heat mode, the thermostat controls the heating system. In the cool mode, the thermostat controls the cooling system. In heat & cool mode, the thermostat controls both the heating and cooling systems. The Amana® 2246007 also has a button lockout feature. This enables the thermostat to be set to the proper mode and temperature and locked so it cannot be tampered with.

Button Functions

• UP: Used to increase the set temperatures and to adjust configuration settings.
• DOWN: Used to decrease the set temperatures and to adjust configuration settings.
• SYS (left): Used to change from OFF, HEAT, ELECTRIC HEAT, COOL and AUTO changeover modes
• FAN (right): Used to turn on and off the indoor fan.
• UP, SYS and FAN: Held in simultaneously for 10 seconds to lock and unlock the thermostat.
• DOWN and SYS: Pressed simultaneously to display outdoor temperature if outdoor remote sensor is connected.

Operating Modes

There are four possible operating modes for the Amana® 2246007. Off, Cool, Heat, and Cool & Heat modes are accessed by pressing the SYS (left) button.

OFF Mode

• In this mode, the thermostat will not turn on the heating or cooling devices
  • Note: The indoor fan can be turned on manually in every operating mode by pressing the FAN (right) button. The word FAN shows on the display and the fan icon appears when the fan operates.

Heat Mode

• In this mode, the thermostat controls the heating system. When the heat outputs, the flame icon apprears on the display.
  • Note: For heat pumps, there is a four minute delay for your compressor to restart after it has turned off. To bypass the compressor time delay, go to OFF mode for 5 seconds.

Electric Heat Mode (Heat pump systems only)

• In Electric Heat mode, the heat pump system will be disabled and auxiliary heat will become the primary source of heat.

Cool Mode

• In this mode, the thermostat controls the cooling system. When the cooling outputs, the snowflake icon apprears on the display.
  • Note: There is a four-minute delay for your compressor to restart after it has turned off. To bypass the compressor time delay, go to OFF mode for 5 seconds.

Cool and Heat Mode (Auto Changeover)

• In this mode, the thermostat controls the cooling and heating systems, automatically changing over from one to the other as needed.
• The timing display alternates with the set temperature every 10 seconds in the cool and heat mode.

Testing the Thermostat

Once the thermostat is configured, 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.

Heat Test

1. Press SYS (left) button until heat mode is displayed.
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 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 delay to protect your compressor after it turns off. To bypass the compressor time delay, go to OFF mode for 5 seconds.

Cool Test

1. Press SYS (left) button until cool mode is displayed.
2. Adjust set temperature so it is 5 degrees below room temperature.
3. A/C 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 . To bypass the compressor time delay, go to OFF mode for 5 seconds.

Fan Test

1. Press FAN (right) button. Fan displays. Indoor fan turns ON.
2. Press FAN (right) button. Indoor fan turns OFF.

Lockout Feature

The Amana® 2246007 has a button lockout feature so the mode cannot be changed and the temperature adjustment is limited. Select the appropriate lockout from Configuration Mode Settings (Step 8) of this guide.

To activate the LOCK feature:

1. Simultaneously press the SYS, FAN and UP buttons for 10 seconds.
2. will display and the lockout function will be enabled.

To deactivate the LOCK feature, repeat steps 1 and 2 above.

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, check Gas/Electric Configuration (see Configuration Mode Setting 6)
All thermostat buttons are inoperative	Verify 24 VAC is present; unit locks out when 24 VAC is not present
No response with first button press	First button press activates backlight only
Thermostat turns on and off too frequently	Adjust temperature differential (see Configuration Mode Settings 2 & 3)
Fan runs continuously	Press FAN (right) button to turn fan off
Room temperature is not correct	Calibrate thermostat (see Configuration Mode Setting 11) If remote sensor is used, check S1 and S2 terminal connections
displays when any button is pressed	Thermostat has the button lockout function activated (see Lockout Feature and Configuration Mode Setting 8)
on display instead of room temperature	Check for a bad connection at S1 and S2 terminals, if used (see Configuration Mode Setting 13)
Heat or Cool not coming on	Verify wiring is correct, gently pull on each wire to verify there is a good connection at terminal block
Problem not listed above	Press Reset button once*

Reset Button Function: Display is refreshed, configuration settings are unchanged.
