Low Battery Warning
When the batteries are low, the battery

AA batteries in the unit need to be replaced.
These batteries are not for operation, but
provide battery backup for your settings. The
thermostat requires 24VAC for operation, and
Displaying Fahrenheit or Celsius
Whether the temperature display panel displays in
Fahrenheit or Celsius depends on the position of the
F/C jumper. The F/C jumper is at the top right of the
PCB, called Jumper 4 in the diagram below.

heit (the default setting).

With the jumper placed on both pins, the display is
in Celsius (centigrade).
When the jumper is changed, you
must press the RESET button on the
front of the thermostat.
Setting a Heat Pump's AUX ONLY Mode
If you have a heat pump with auxiliary heat and the
heat pump is not working or cannot keep up with heat
demand, you can use the auxiliary heat only.
Move the jumper from position 2B [heat pump] to
position 2A [Aux only].
Network
the HVAC system will stop function if the thermostat
loses power.
Replace the batteries as soon as you see the flashing
battery icon. Press the RESET button after replacing
batteries.
