The FILTER Monitor counts the hours since the filter in your blower was last changed. After

250 hours of use, FILTER will appear in the display. After you change the filter, set the
thermostat’s FILTER Monitor back to zero as follows.

A thermostat works by turning your heating or cooling system on and off whenever the

room temperature varies a certain number of degrees from the set-point temperature. This
variation is the “swing.”

Your system should cycle on about 3 to 6 times per hour. A smaller swing number

increases the number of cycles, so room temperature is more constant. A larger swing
number decreases the number of cycles, to save energy in most cases.

Your thermostat has an internal timer built in to protect your compressor. The timer forces a

minimum on/off time of 5 minutes. You may change this minimum on/off time to 2 minutes. To
accomplish this, remove the jumper labeled 5/2 MIN. You must press the small reset button on
the face of the thermostat for the changes to take effect.
