INSTALLER/CONFIGURATION MENU

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 menu item 26) (3 heat/2 cool)

SS1 – Single Stage System (3 wire zone see wiring diagram 37-6808A)

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 thermo- stat switches the option to ELE.

3)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 by pressing touch keys,or. If "0 Days" is selected for non-program- mable mode, the step for EMR will be skipped, as this feature will not be available in this mode.

4)Program Steps per day – This control can be config- ured for 4 or 2 program steps per day. Default is "4 PS"

and can be toggled between 4 PS and 2 PS by pressing theortouch keys.

5)System Switch Configuration (MS2/SS1) – This thermostat is configured for Heat and Cool with Auto changeover default (Cool-Off-Heat-Auto). 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 available namely, Emer for Emergency Mode.

6)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: Let us say, 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 setpoint 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 slow cycling (SL, Cr), press touch keysortoggle between FA & SL. The cycle rates are as below different

selections:
Mode	Fast rate	Slow rate
Heat	0.6°F	1.2°F
Cool	1.2°F	1.7°F
Emer	1.2°F	1.7°F

10)Select Compressor Lockout (CL) – Selecting CL On will cause the thermostat to wait 5 minutes between cooling cycles. This is intended to help protect the compressor from short cycling. Some of the newer compressors have already got a time delay built in and do not require this feature to be activated in the thermo- stat. Your compressor manufacturer 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 – In low lighting condi- tions, 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 Backlight Intensity – This thermostat has the

ability to provide two selectable intensities of the back- light: HI and LO. Usingortouch keys you can toggle the selection between HI and LO.

13)Select Temperature Display Adjustment 4 LO to 4 HI This allows you to adjust the room temperature display

by an amount in the range of -4°F to +4°F in 1° steps by using theortouch keys. Your thermostat was accurately calibrated at the factory, however you have the option to change the display temperature value to match your previous thermostat, if you so prefer.

14)Select °F or °C Readout – Select the desired temper-

ature unit by pressing	or		. Factory default is °F.

15)Select Audio Prompting (Beeper) On or Off – Factory default setting is on (b, On). If you wish to turn off the beeper select OFF.

16)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.

17 & 18) Select Automatic Schedule – 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.

19)Select Cool Savings™: With Cool Savings™ enabled, the thermostat will make small adjustments to the setpoint temperature during periods of high demand to reduce AC system running time and save energy. When the cooling system has been running for more than 20 minutes, humidity in the home will be lower and a higher temperature will feel comfortable. After 20 minutes of run time, the thermostat will start increasing the setpoint temperature in steps of less than one degree as the system continues to run. These adjustments will eventu- ally cause the system to satisfy the thermostat to turn the system off and reduce the energy consumption. When the Cool Savings™ feature is active and making adjust- ments, the display will flash “Cool Savings”. The amount of the adjustments to the setpoint temperature is depen- dent on the Cool Savings™ value that is set, 1 being the least adjustment and 6 being the most adjustment. With this feature set to OFF, no change will occur when the AC system is continuously running during the periods of high demand. Periods of high demand will normally occur during the late afternoon and early evening on the hottest days of the summer. As demand lessens the adjustments to setpoint temperature are reversed until setpoint temperature returns to normal and “Cool Savings” no longer flashes.
