5. Select filter replacement run time – The thermostat will display “FLTR” after a set time of operation. This is a
reminder to change or clean your air filter. This time can be set from 0 to 1950 hours in 50 hour increments. A
selection of 000 will cancel this feature. When “FLTR” is displayed, you can clear it by pressing HOLD and
RUN at the same time. This resets the timer and starts counting the hours until the next filter change. Changing
the time in the menu also resets the timer.
6. Select Compressor Lockout LOC OFF or ON – Selecting LOC 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 a
minimum of 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 feature is already present in their system. When the compressor
time delay occurs it will flash the (snowflake icon) for about five minutes then turn on the compressor.
7. Select Temperature Display Adjustment 4 LO to 4 HI – Allows you to adjust the room temperature display
+/- 4°. Your thermostat was accurately calibrated at the factory but you have the option to change the display
temperature to match your previous thermostat.
8. Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.
