1. Turn off power to heating and cooling system by removing
the fuse or switching off the appropriate circuit breaker.
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.
6. Refer to the following section for instructions on how
to install this thermostat.
PACKAGE CONTENTS/TOOLS REQUIRED
Package includes: Thermostat on base, thermostat cover,

following steps:
Note: Operation being set will blink in the display.
1. Slide the Function switch to the OFF position.
2. Remove the thermostat’s front cover.
3. To enter the configuration mode, simultaneously hold
the LEFT and RIGHT buttons in for 6 seconds while the
thermostat is in OFF mode. (See diagram on page 3.)
4. Once in the configuration mode, press the
< or > button
to change settings within each screen.
