INSTALLER/CONFIGURATION MENU
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 35) (3 heat/2 cool)
SS1 – Single Stage System (3 wire zone see wiring diagram
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
Days" or "0 Days" can be selected by pressing touch keys,
or
. If "0 Days" is selected for
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 the
or
touch keys.
5)System Switch Configuration (MS2/SS1) – This thermostat is configured for Heat and Cool with Auto changeover default
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
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 keys
or
toggle 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. Using
or
touch 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 
or
touch 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 – With just one touch
of the Auto Schedule key this feature allows you to program a desired comfort temperature into all the program periods along with a 6° set back for night periods of both Heat and Cool programs. Factory default is "On" for both. When Heat AS On and Cool AS On are activated while in Heat or Cool mode, select desired setpoint temperature and press Auto Schedule. Auto Schedule will flash, press it again to copy. This value will be copied into all the morning, day and evening program periods. The night program periods will be with a 6°F set back.
19)Select Cool Savings™: With Cool Savings™ enabled, the thermostat will make small adjustments to the sensed 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 decreasing the sensed 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 “CoolSavings”. The amount of the adjustments to the sensed 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 sensed temperature are reversed until sensed temperature returns to normal and “CoolSavings” no longer flashes.
