1) System Configuration - Selects SS (Single Stage) or HP

(Heat Pump) operating mode. Default configuration is SS.

For Heat Pump operation choose HP.

2) Select CS (Cool Savings™) - With Cool Savings™

enabled, the thermostat will make small adjustments to

the Setpoint temperature during periods of high demand

to reduce cooling 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

setpoint 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 eventually cause

the system to satisfy the thermostat and turn the system

off to reduce the energy consumption. When the Cool

Savings feature is active and making adjustments, the

display will show “Save”. The amount of the adjustments to

the setpoint temperature is dependent 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 cooling 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.

3 & 4) Select Cycle Rate Selection - The factory default setting

for Single Stage Heat is Medium Cycle (ME). For Single

Stage Cool the default setting is fast (FA). To change cycle

rate, press the

and

buttons.

The cycle rate differentials for different settings are:

5) Select Compressor Lockout CL OFF or ON - 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 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.

6) Select Backlight Display - The display backlight improves

display contrast in low lighting conditions. When the “C”

terminal is connected, selecting backlight CdL On will keep

the light on continuously. Select backlight OFF will turn the

light on momentarily when any key is pressed. When the

“C” terminal is not connected, regardless of the backlight

selection, the light will be on momentarily when any key is

pressed.

7) 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 display

temperature to match your previous thermostat. The

current or adjusted room temperature will be displayed on

the display.

8) Select F° or C° Readout - Changes the display readout to

Celsius or Fahrenheit as required.

9) Select Filter Replacement Reminder and Set Run Time

Select the “Change Filter” reminder On or OFF. If selected

On, press

and

to select the time period from 25 to

1975 hours in 25 hour increments. In a typical application,

200 hours (default) of run time is approximately 30 days.

After the selected time of blower operation, the thermostat

will display “Change Filter” as a reminder to change or

clean your air filter. When “Change Filter” is displayed,

press the

and

button to clear the display and

restart the time to the next filter change. A selection of OFF

will cancel this feature.
