CAUTION
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including
interference that may cause undesired operation.
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
thermostat 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.
