Operating Features, Setting the Thermostat

2)Select FA or SL (Fast or Slow) Heating Cycle Rate - The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is nor- mally for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system just under I°F and the SL setting cycles at approxi- mately 1.5°F.

5)Select Compressor Lockout (LOC OFF or ON) - Select- ing LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It wilt also wait 5 minutes minimum 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 feature is already present in their system. When the com- pressor time delay occurs it will flash the (snowflake icon) for about five minutes then turn on the compressor.

6)Select Temperature Display Adjustment (4 LO to 4 Hi) - Allows you to adjust the room temperature display 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.

7)Select Temperature Display (°F or °C) - Changes the display readout to Celsius or Fahrenheit as required.
