 INSTALLER/CONFIGURATION MENU

1.  This control can be configured for:
  

HP1

 – Heat Pump with one stage of compressor (1 

heat/1 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. 

Stage Cycle Completion (SC) 

– Selecting (SC ON) will

 

cause the thermostat to complete heating and/or cooling 
cycles on the highest stage engaged during the cycle. 
Thermostat will not reduce heating or cooling stages be-
fore the heating or cooling cycle is satisfied and all stages 
are turned off.

12. 

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.

13. 

Select Continuous Display Lighting (dL) 

– In low 

lighting conditions, display backlight improves the display 
contrast. (See Table 1)

14. 

Select Temperature Display Adjustment 5 LO to 5 HI

 

This allows you to adjust the room temperature display 
by -5°F to +5°F in 1° steps. Your thermostat was accu-
rately calibrated at the factory, however you have the 
option to change the display temperature value to match 
the previous thermostat, if you so prefer.

15. 

Select °F or °C Readout

 – Changes the display readout 

to Celsius or Fahrenheit as required.

16. 

Select Audio Prompting (Beeper) On 

or

 Off

 – Factory  

default setting is 

b, On

. If you wish to turn off the beeper 

select OFF.

17. 

Select Daylight Saving Time Calculation 

– This feature 

will allow the thermostat to calculate the DST automatically 
and apply it to the Real Time Clock display. Default  is On. 

18 & 19.

 Select Automatic Schedule

 – Not available if 

configured for non-programmable. This feature allows  
programming a “Comfort Temperature” into all program 
periods with the 

Auto Schedule

 key. When 

Heat AS

 

(for Heat mode) or 

Cool AS

 (for Cool mode) is selected

 

On

, the Auto Schedule feature is ready to be set. 

Off

 

indicates that the feature is not ready to be used or a 
“Comfort Temperature" is already set. See Auto Schedule 
in Programming section.

20 & 21. 

Select Cool Savings™ 

– Cool Savings™ provides an 

energy saving temperature offset (from 1-6 degrees) under 
peak cooling load conditions (high outdoor temperatures).
