Safety Warnings
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.

Make sure your Heater/Air Conditioner
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 system at the main fuse
panel. Most residential systems have
a separate breaker for disconnecting
power to the furnace.
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.
Preparation
OWNER'S MANUAL
S1-THEC11NS

Remove the cover of the old thermostat.
If it does not come off easily check for
screws.
Loosen the screws holding the thermostat
base or subbase to the wall, and lift away.
Disconnect the wires from the old
thermostat. Tape the ends of the wires
as you disconnect them, and mark them
with the letter of the terminal for easy
reconnection to the new thermostat.
Keep the old thermostat for reference
purposes, until your new thermostat is
functioning properly.
