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.
P/N TSTATG2100-2
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.

Heat to satisfy the heat demand.
Normal - Aux Heat is allowed to run, if necessary,
along with the heat pump to satisfy the
heat demand.
Lockout - Aux Heat will never turn on
regardless of the heat demand.
When the Aux Heat switch is in the Emergency position the
compressor will also be locked out during cooling operation.

Make sure your Heat Pump is working
properly before beginning installation
of the thermostat.
Carefully unpack the thermostat.
Save the screws and instructions.
Turn off the power to the Heat Pump
system at the main fuse panel.
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 TSTATG2100-2

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.

originating inside the wall from
entering the thermostat.
These drafts, left unchecked, may
cause incorrect room temperature

Test Operation
On the thermostat, slide the Mode Switch
to HEAT. Press the COOLER or WARMER
button until the set temperature is 10 degrees
above room temperature. The HVAC unit
should energize in the heating mode.
Note: You may need to wait up to five minutes
for heating to energize due to the compressor
lockout feature. There is a two minute min-
imum run-time for first stage heating.
OWNER'S MANUAL
On the thermostat, slide the Aux Heat
Switch to the NORMAL position. The
Aux Heat icon will appear indicating that
the thermostat has energized Aux Heat
(page 7).
TWO STAGE OPERATION - The 2nd stage
of heat (auxiliary heat) is turned on when
the room temperature is equal to or less
than: the setpoint minus the 1st stage
deadband (one degree, non-adjustable),
minus the 2nd stage deadband (two
degrees, non-adjustable).
