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
The cycle rate differentials for different settings are:

SS Cool
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.
