INSTALLER/CONFIGURATION MENU

The configuration menu allows you to set certain thermostat
operating characteristics to your system or personal
requirements. To enter the menu: Set your thermostat switch to
OFF. Press and hold the

and

buttons simultaneously

for approximately 5 seconds. The display will change to
show the first item in the configuration menu. Press the

button to change the setting. Press the

and

buttons simultaneously again to change to the next menu item.
Continue through all steps to accept your new settings. To exit
the menu set the system switch to

COOL, HEAT or EMER. If

no keys are pressed within fifteen minutes, the thermostat will
revert to normal operation.
1) 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.

2 & 3) Select Cycle Rate Selection - The factory default

setting is (FA, CR) for all modes (Heat Pump, Heat Pump
Aux, Heat and Cool). To change to slow cycling (SL, CR),
press the

keys to toggle between FA & SL.

The cycle rate differentials for different settings are:

MODE

Fast

Slow

Heat Pump

1.2°F

1.7°F

HP Aux

0.8°F

1.2°F

4) 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.
