2. Programming Mode [note 1] – Selects the programming mode, either full 7 day or 5-2 day (weekday/ weekend) programming or non-programmable.
3. Clock Type – Selects either a 12 hour or 24 hour clock.
4. Temperature Scale – Selects a temperature scale of either °F or °C.
5. Auto Changeover – Selects auto changeover on or off. When auto changeover mode is enabled and selected, the system automatically switches between heating and cooling modes. There is a 5-minute delay when switching from heating to cooling or cooling to heating in auto changeover mode.
   NOTE: Also see “Auto Changeover Dead Band” in option 22.
6. System Type – Selects the system type for your installation.
   NOTE: Changes made to this option will reset options 7 through 15 back to their default values depending on the system type.
7. 1st Stage Differential – Selects a 1st stage temperature differential.
8. 2nd Stage Differential [note 2] – Selects a 2nd stage temperature differential.
9. 3rd Stage Differential [note 2] – Selects a 3rd stage temperature differential.
10. 1st Stage Fan Control [note 3] – Selects a 1st stage fan control of either gas or electric heat.
11. Emergency Heat Fan Control [note 4] – Selects emergency heat fan control of either gas or electric heat.
12. Reversing Valve [note 5] – Selects the output state of the O/B terminal. Select O for this terminal to be active in the cool mode or select B for this terminal to be active in the heat mode.
13. Auxiliary Fossil Fuel Heat Pump Control [note 4] – When set to electric (AE AUX), both the compressor (1st stage) and auxiliary stage(s) will run when a call for auxiliary heat is made. When set to gas (AG AUX), the compressor stage(s) will be locked out one minute after a call for auxiliary heat.
    NOTE: This option can be overridden if setting an auxiliary heat balance point in Option 24.
14. Compressor Power Outage Protection [notes 4, 6] – Selects power outage protection on or off. When enabled, this thermostat will provide cold weather compressor protection by locking out the compressor stage(s) of heating for a period of time after a power outage greater than 60 minutes.
15. AC Power Interrupt Warning [note 6] – When enabled, the thermostat will display an outage warning when AC power to the thermostat is lost.
16. Short Cycle Protection [note 7] – Selects the number of minutes the cooling compressor will be locked out after turning off. This short cycle protection is also active in the heat mode if a heat pump system was selected in Option 6.
17. Residual Cooling Fan Delay [note 7] – Selects a delay for the system fan after the cooling compressor has turned off. This delay will help remove the remaining cool air out of the ductwork providing additional efficiency.
18. Circulating Fan Lock – When enabled, the only user fan options available are ON and CIRC (Circulation).
    The AUTO option is not available with this option enabled.
19. Adaptive Recovery Mode (early recovery) [note 8] – Enables or disables the ARMTM (adaptive recovery mode) feature. During ARM, room temperature is recovered by turning on the heating or cooling before the end of the set back period. The set point temperature is changed to that of the upcoming program temperature.
20. Indoor Remote Sensor Control [note 9] – If an indoor remote sensor is connected during installation, the thermostat will automatically detect the sensor. When an indoor sensor is detected, you may select between thermostat only (I SENS), remote sensor only (E SENS) or combining the thermostat and the remote sensor (A SENS). NOTE: This option does not apply to an outdoor sensor. When an outdoor sensor is connected the thermostat automatically recognizes it and no further configuration is necessary.
21. Lockout Security Level – Selects the level of keypad lockout when the thermostat is locked. Level 2 locks the entire thermostat (including the front reset button). Level 1 locks everything except the / buttons, allowing for up and down temperature adjustment. NOTE: The lock code is set in the User Settings mode (see User Manual).
22. Auto Changeover Dead Band [note 10] – When auto changeover mode is enabled in option 5 and selected, the system automatically switches between heating and cooling when the room temperature meets the normal criteria for either a heating or cooling call. There is a forced separation (dead band) between the heating and cooling set points so that the systems do not work against each other. This option selects the amount of this dead band in degrees with the default being 3° F.
23. Compressor Balance Point [notes 4, 11] – Locks out the use of the compressor heat stage when the outside air temperature is less than the selected setting of 15° F to 50° F (-9° C to 10° C)
24. Auxiliary Heat Balance Point [notes 4, 11] – Locks out the use of the auxiliary heat stage when the outside air temperature exceeds the selected setting of 70° F to 40° F (21° C to 4° C). NOTE: This balance point overrides the fossil fuel compressor lockout in option 13. If this option is set to gas and the outdoor temperature is over the auxiliary balance point, the compressor will remain on during a call for auxiliary heat.
25. Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.
26. Cool Set Point Lower Limit [note 7] – Selects the cooling set point lower adjustment limit.

System Testing

Warning Read Before Testing

• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the compressor from short cycling. When testing the system, make sure to take this delay into account.

NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.
All user settings will be returned to factory default, however all Installer settings will remain as originally programmed in section 4.

1. Press the SYSTEM button until the thermostat is in HEAT mode.
2. Using the button, raise the set temperature a minimum of 3 degrees above the current room temperature. The system should start within a few seconds. With a gas heating system, the fan may not start right away.
3. Press the SYSTEM until the thermostat is in the OFF mode. Allow the heating system to fully shut down.
4. Press the SYSTEM until the thermostat is in COOL mode.
5. Using the button, lower the set temperature a minimum of 3 degrees below the current room temperature. The system should start within a few seconds (unless compressor short cycle protection is active – See note above).
6. Press the SYSTEM until the thermostat is in the OFF mode. Allow the cooling system to fully shut down.
7. Press FAN until the thermostat is in FAN ON mode. The system fan should start within a few seconds.
