Installer Guide 4
The two Alkaline “AA” batteries must be replaced at least once every 12
months to ensure proper operation. The Low Battery icon will appear on the
display when it is time to replace the batteries. If the thermostat is connected
to 24v power, the batteries should still be installed, but are not required.
When “Low Battery” 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.
Annual battery replacement is especially critical in locations subject to
freezing temperatures. The thermostat will be unable to turn on the heating
system if the batteries are exhausted.
