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 or keys to toggle between FA & SL. The cycle rate differentials for different settings are:

MODE	Fast	Slow
	FA	SL
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.
