CAUTION

Follow Installation Instructions carefully.

DISCONNECT POWER TO THE HEATER ­AIR CONDITIONER BEFORE REMOVING
THE OLD THERMOSTAT AND INSTALLING
THE NEW THERMOSTAT.

WARNING

CAUTION

The 2 Alkaline “AA” batteries must be replaced at least
every 12 months to assure proper operation.
The thermostat will display the Low Battery
code (fig. 1) on the display of the thermostat
when it is time to replace the batteries. If the
thermostat is connected to 24v power, the
Batteries may still be installed, but are not required.

When is displayed the batteries must be replaced
immediately. The manufacturer cannot be liable for
improper operation of the thermostat if the batteries are
not immediately replaced.

The annual battery replacement is especially critical in
locations subject to freezing temperatures. The
thermostat will be unable to turn on the Heat if the
batteries are exhausted.

Installation / Battery
Replacement

Open The New Thermostat

The top of the thermostat housing has two (2) screw­driver slots to assist when seperating.

To pull the housing apart, insert a small blade screw­driver into the slot and rotate 90 . This will release
the top housing snaps.

Repeat the procedure in the other screw driver slot.

Separate the housing halves by pulling the top
forward until the pins release, and then lift the bottom
out.

The batteries must be replaced
immediately when the thermostat
displays the Low Battery code (fig.1).
