Purchaser assumes all risks and liability for incidental and consequential damage resulting from
installation and use of this unit. Some states do not allow the exclusion of incidental or consequential

you may also have other rights which vary from state to state. Applicable in the U.S.A. only.
TEMPERATURE SWING
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 thermostat is carefully tuned to provide you with exceptional comfort as well as provide you
with energy savings. Should you desire to have the temperature controlled even more tightly in
your home at the expense of increased energy savings, you can change the swing value. Also
users of forced hot water systems may find this setting more comfortable.
Located on the back of the thermostat body are three jumpers.
To change from 0.5 degree F control to 0.25 degree F control, remove the jumper indicated by
0.5 F / 0.25 F.
Press the small unmarked button on the front of the thermostat with a paper clip for the change
to take effect. The unit will now control your home to 0.5 degrees.
5 MIN/ 2 MIN MINIMUM RUN TIME
Your thermostat has an internal timer built in to protect your compressor. The timer forces a
minimum on-time of 5 minutes. You may change this minimum on-time to 2 minutes. To
accomplish this, place the jumper labeled W3 over both pins. You must press the small
unmarked button on the face of the thermostat for the changes to take effect.
