Important Safety Information
WARNING!: Always turn off power at the main power supply before installing, cleaning,
or removing thermostat.
• This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC
• Do not short across terminals of gas valve or system control to test operation; this will damage your
thermostat and void your warranty
• All wiring must conform to local and national electrical and building codes
• Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage
your A/C system and cause personal injuries
• Use this thermostat only as described in this manual

To Remove Existing Thermostat
ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing
the fuse or switching the appropriate circuit breaker to the OFF position before
removing the existing thermostat.
1. Turn off power to the heating and cooling system by removing the fuse or switching the appropriate
circuit breaker off.
2. Remove cover of old thermostat. This should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
To Install Thermostat
ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing
the fuse or switching the appropriate circuit breaker to the OFF position before
removing the existing thermostat.
IMPORTANT: Thermostat installation must conform to local and national building and
electrical codes and ordinances.
Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an
outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.
1. Turn off power to the heating and cooling system by removing the fuse or switching the appropriate
circuit breaker off.

Remote or Outdoor Sensor Installation (Optional)
1. Remove cover from remote sensor housing.
2. Select an appropriate location for mounting the remote sensor.
3. Mount remote sensor unit using hardware provided.
4. Install two strand shielded wire between remote
sensor and thermostat. Shielded wire must be
used. Do not run remote sensor wire in conduit
with other wires.
• Wire 1 should run between the S1 terminal on the
thermostat and the S1 terminal on the remote sensor
• Wire 2 should run between the S2 terminal on the
thermostat and the S2 terminal on the remote sensor
• Connect the shielding of the wire to the S2 terminal on the thermostat
5. Configure the thermostat to operate with the remote sensor (see Configuration Mode setting 11).
Note: Remote or outdoor sensor reading can be displayed by simultaneously pressing the down
and SYS buttons.
If your LCD is blank, or displaying LO BAT, the batteries are not installed or need to be changed. We
Hardwired
5-Wire, Two Transformer suggest you change the batteries at least once a year, or whenever the LO BAT warning displays.
(Both transformers must be in phase)
Remove the cover, and install the two "AAA" alkaline batteries into the battery compartment. Proper
battery installation is important! Make sure the positive ends of the batteries match the positive
terminals in the battery compartment.
Batteries will provide power to maintain the clock during a power loss.
