1.This control can be configured for:
MS2 –
HP1 – Heat Pump with one stage of compressor (2 heat/1 cool)
HP2 – Heat Pump with two stage compressor or two compressor system, Gas or Electric backup; (Dual Fuel see menu item 27) (4 heat/2 cool)
SS1 – Single Stage System and 3 wire zone systems see wiring diagrams..
2.GAS or Electric (ELE) fan operation.. If the heating system requires the thermostat to energize the fan, select ELE.. Select GAS if the heating system energizes the fan on a call for heat.. Note: Resetting the thermostat switches the option to GAS.
3.O/B Terminal selection – Selects the operation of the reversing valve (when item 1 is set to HP1 or HP2 only).. When set to "O" the changeover valve will be energized in COOL to accommodate the majority of heat applica- tions.. If the heat pump requires the changeover valve to energize in HEAT, select "B"..
4.Programs per week – This control can be configured for 7 independent day or 5/1/1 day programming or nonpro- grammable modes.. Default is
5.System Switch Configuration (MS2/SS1) – This ther- mostat is configured for Heat and Cool with Auto change- over default
When the control is in heat pump configuration (HP1/ HP2), the system switch configuration will have an additional mode available, Em for Emergency Mode..
6.Energy Management Recovery (EMR) – (this step is skipped if configured as
Example: The heating program is 65°F at night and 70° at 7 AM.. If the building temperature is 65°F, the difference is 5°F.. Allowing 5 minutes per °F rise, the thermostat set- point will change to 70° at 6:35 AM.. Cooling allows more time per °F, because it takes longer to reach temperature..
7, 8 & 9.. Cycle Rate Selection – The factory default setting is fast cycle (FA Cr) in all modes (Heat, Cool, Emer).. To change to slow cycling (SL, Cr), press touch keys
or 
toggle between FA & SL.. The cycle rates are below:
Mode | Fast rate | Slow rate |
Heat (SS1, MS2) | 0..6°F | 1..5°F |
Cool (SS1, MS2) | 1..2°F | 1..7°F |
Heat Pump (HP1, HP2) | 1..2°F | 1..7°F |
Emer Heat (HP1, HP2) | 0..6°F | 1..7°F |
10.Select Compressor Lockout (CL) – Selecting (CL On) will cause the thermostat to wait 5 minutes between cool- ing cycles.. This is intended to help protect the compressor from short cycling.. Some of the newer compressors have a time delay built in and do not require this feature to be activated in the thermostat.. Your compressor manufactur- er can tell you if this lockout feature is already present in their system.. When the thermostat compressor time delay is activated, it will flash the set point for up to five minutes..
11.Select Continuous Backlight (dL) – In low lighting con- ditions, display backlight improves the display contrast. When C terminal is connected, selecting dL On will turn the backlight on continuously.. Selecting dL Off will turn the backlight on momentarily after any key is pressed.. When C terminal is not powered (battery only), dL On enables the momentary backlight whenever a key is pressed..
12.Select Temperature Display Adjustment 5 LO to 5 HI This allows you to adjust the room temperature display by
13.Select °F or °C Readout – Changes the display readout to Celsius or Fahrenheit as required..
14.Select Audio Prompting (Beeper) On or Off – Factory default setting is b, On.. If you wish to turn off the beeper select OFF..
