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.
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.
Follow Installation Instructions carefully.

Installer Guide 10
• Proper installation of the thermostat will be accomplished by following
these step by step instructions. If you are unsure about any of these steps,
call a qualified technician for assistance.
• These tools will be required:
• Make sure your Heater/Air Conditioner (Heat Pump for PSP2100) is working
properly before beginning installation of the thermostat.
• Carefully unpack the thermostat. Save the screws and instructions.
• Turn off the power to the Heating/Air Conditioning (or Heat Pump for
PSP2100) system at the main fuse panel. Most residential systems have a
separate breaker for disconnecting power to the furnace.
