TROUBLESHOOTING
Reset Operation If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing
and
at the same time when system is
switched from “OFF” to “HEAT” position. This also resets the factory defaults. If the thermostat has power, has been reset and
still does not function correctly contact your heating/cooling ser- vice person or place of purchase.
Batteries For optimum performance, we recommend replacing batteries once a year with fresh “AAA” Energizer
®
alkaline batteries.

by 3
°
F (2
°
C) or more above the actual temperature with the
TEMPERATURE UP key, and the fast second stage feature is enabled, FA on, the second stage will energize immediately. With FA off, second stage will not energize until the setpoint temperature is 1
°
F or more above actual temperature for more
than ten minutes.
3. Select Compressor Lockout CL OFF or ON – Selecting CL
ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling and heating 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 com- pressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compres- sor time delay occurs it will flash the Snowflake and Flame Icons for about five minutes.
4. Select Temperature Display Adjustment 3 LO to 3 HI –
