INSTALLER/CONFIGURATION MENU
1)This control can be configured for:
MS 2 – Multi-Stage System (no heat pump)
HP 1 – Heat Pump with one stage of compressor, Gas or Electric backup
HP 2 – Heat Pump with two stage compressor or two compressor system, Gas or Electric backup
SS 1 – Single Stage System
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.
3)Energy Management Recovery: (this step is skipped if configured to be non-programmable).
Energy Management Recovery (E) On enables the ther- mostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.
Example: E On is selected and your heating is pro- grammed to 65° at night and 70° at 7 AM. If the building temperature is 65°, the difference between 65° and 70° is 5°. Allowing 5 minutes per degree, the thermostat setpoint will change to 70° at 6:35 AM. Cooling and Heat Pump systems allow more time per degree, because it takes longer to reach set temperature.
4, 5 & 6) Cycle Rate Selection – The factory default setting for Heat and Cool modes, SS1, MS2, is medium cycle (ME). For Heat Pump, HP1, HP2, the default setting is medium (ME). For Aux, the default setting is fast cycle (FA).To change cycle
rate, press the 
or 
button.
Cycle rate differentials for different settings are:
MODE | Fast | Medium | Slow |
| FA | ME | SL |
| | | |
Heat (SS1, MS2) | 0.4°F | 0.6°F | 1.7°F |
Cool (SS1, MS2) | 0.9°F | 1.2°F | 1.7°F |
Heat Pump (HP1, HP2) | 0.9°F | 1.2°F | 1.7°F |
AUX (HP1, HP2) | 0.6°F | - | 1.7°F |
| | | |
7)Select Compressor Lockout CL OFF or ON – Selecting CL ON will cause the thermostat to wait 5 minutes be- tween cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay occurs, it will flash the setpoint for up to five minutes.
8)System Mode Configuration – This thermostat is config- ured for Heat and Cool (SYSTEM switch with Heat A/C Off) default. It can also be configured for Heat only with fan (Heat Off fan), Heat only without fan (Heat Off) or Cool only (Cool Off).
9)Compressor Optimization – CO provides a delay in cir- culator fan operation after the compressor turns on or off. With CO selected ON, when the compressor turns on (for a call for heat in heat pump or a call for cool) the fan will be delayed for five seconds before turning on to allow the air to be heated or cooled. After the compressor turns off for call for cool, the fan will continue to run for 20 seconds to circulate all of the cooled air. If CO is set to OFF, there will be no delay in fan operation.
10)Select Backlight Display – The display backlight improves display contrast in low lighting conditions. When the "C" terminal is powered, selecting backlight dL ON will keep the light on continuously. Select backlight OFF will turn the light on momentarily after any button is pressed. When the "C" terminal is not powered, the light will be on momentarily after any button is pressed no matter whether the backlight is selected ON or OFF.
11)Select Temperature Display Adjustment 4 LO to 4 HI – Allows you to adjust the room temperature display up to 4° higher or lower. Your thermostat was accurately calibrated at the factory, but you have the option to change the dis- play temperature to match your previous thermostat. The current or adjusted room temperature will be displayed.
12)Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.
13)Program Options: Selects configuration for 7 day (7) or non-programming (0) mode. The default setting is 0, indi- cating non-programming. The programs per week can be
changed by pressing the 
or 
buttons. A selection of 0 days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.
14)Program Steps per day – This control can be configured for 4 or 2 program steps per day. Default is "2 PS" and can be toggled between 4 PS and 2 PS.
15 & 16) Select Fast Second Stage ON or OFF – Heat pump or Multi-stage only, in the run mode, with the fast Heat feature enabled (On FA Heat), if the Heat setpoint temperature is manually raised by 3°F (2°C) or more
above the actual temperature using 
the second stage will energize immediately. With FA OFF, second stage will not energize until the setpoint temperature is 1°F or more above actual temperature for more than ten minutes. The Fast Cool feature (FA Cool) provides the same controls when the setpoint temperature is lowered.
17)Select Daylight Saving Time Calculation – This feature will allow the thermostat to calculate the DST automati- cally and apply it to the Real Time Clock display. Default
On. Use 
or 
touch keys to select the feature OFF.
18)Limited Heat Range – This feature provides a maximum setpoint temperature for heat. The default setting is 99°F. It can be changed between 62°F and 98°F by pressing the 
or 
button.
19)Limited Cool Range – This feature provide a minimum setpoint temperature for cool. The default setting is 45°F. It can be changed between 46°F and 82°F by pressing the 
or 
button.
20)Select Dual Fuel Setting (dF) – HP1 or HP2 systems. 0 is default OFF for Elect. Aux. If your system has a fossil fuel (gas or oil) Auxiliary heat, select 1 to 9. See Dual Fuel setting and compressor delay on the following page.
Select Compressor Delay (Cd) – Available only if dF 1 to 9 is selected above. After the auxiliary heat is turned on, the compressor(s) shut down is delayed for the time se- lected (in seconds). This delay is factory set to 60, but can
be set in the range of 0 to 99 using 
or 
buttons.
21)Select Reversing Valve Output – The O/B option is factory set at "O" position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermo- stat you are replacing or the heat pump being installed with this thermostat requires a "B" terminal, to energize the changeover relay in HEAT, the O/B option should be set at "B" position.
