1.This control can be configured for:

MS2 – Multi-Stage System (2 heat/2 cool)

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 screen reference number 33) (4 heat/2 cool)

SS1 – Single Stage System (3 wire zone 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 non- programmable modes. Default is 7-day mode. The display indicates "7 Days" as default. Other options "5 Days" or "0 Days" can be selected. If "0 Days" is selected for non- programmable mode, the step for EMR will be skipped, as this feature will not be available in this mode.

5.Program Steps per day – Not available if configured for non-programmable. This control can be configured for 4 or 2 program steps per day. Default is "4 PS" and can be toggled between 4 PS and 2 PS.

6.System Switch Configuration (MS2/SS1) – This ther- mostat is configured for Heat and Cool with Auto change- over default (Cool-Off-Heat-Auto). It can be configured as Heat & Cool (Cool-Off-Heat), or Heat Only (Off-Heat), or Cool Only (Cool-Off).

When the control is in heat pump configuration (HP1/ HP2), the system switch configuration will have an additional mode, Em for Emergency.

7.Energy Management Recovery (EMR) – (this step is skipped if configured as non-programmable). When set to "On" causes the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify.

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. 8, 9 & 10. Cycle Rate Selection – The factory default setting

is fast cycle (FA Cr) in all modes (Heat, Cool, Em). To change to slow cycling (SL, Cr), press touch keys or

toggle between FA & SL. The cycle rates are below:

Mode	Med	Slow
Heat	0.6°F	1.5°F
Cool	1.2°F	1.7°F
Heat Pump	1.2°F	1.7°F
Emer Heat	0.6°F	1.7°F

11.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
