unplugging the unit or by removing the fuse or
switching the appropriate circuit breaker to the OFF
position before removing the existing thermostat.
TO REMOVE EXISTING THERMOSTAT
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,
2 “AAA” batteries, wiring labels, screws and wall anchors.
Tools needed: Drill with 3/16sbit, hammer, screwdriver and
putty.

TO INSTALL THERMOSTAT (cont.)
1. Turn off power to the heating and cooling system
by removing the fuse or switching off the appropriate
circuit breaker.
2. Move the Function switch on the thermostat to Off.
3. Remove the cover by inserting and twisting a coin or
screwdriver in the slots on the top of the thermostat.

6. Set thermostat base and cover away from working area.
7. Using a 3/16sdrill bit, drill holes in the locations you
have marked for mounting.
8. Use a hammer to tap supplied anchors in mounting holes.
9. Align thermostat base with mounting holes and feed
the control wires through the wire opening.
10. Seal hole for wires behind thermostat with non-flammable
insulation or putty, or use a wall plate obtainable from
a local hardware or home building store.
11. Use supplied screws to mount thermostat base to wall.
12. Insert stripped, labeled wires in matching wire terminals
by pressing on the corresponding terminal contact. See
the “Wiring Diagrams” section of this manual.
CAUTION! Make sure exposed portion
of wires does not touch other wires.
13. Gently tug wire to be sure of proper connection.
Double check that each wire is connected to the
proper terminal.
