materials:
■ Slotted Screwdriver
■ Electric drill and
3/16" bit
■ Hammer

Alkaline batteries
Remove Old Thermostat
CAUTION: Do not remove any wiring from existing
thermostat before reading the instructions
carefully.
Wires must be labeled prior to removali.
<4 Turn your existing thermostat to OFF position.
I Turn off the power to the furnace at the main
power panel to avoid electrical shock.
j
Remove existing thermostat cover and
thermostat. Some thermostats will have screws
2
or other locking devices that must first be removed.
Once wall is exposed, look for wires.
If wires are not visjbie. they may be connected to the
back of wallpiate. Again, look for screws, tabs, etc.
Some models have doors that open to expose wires
and mounting screws (see Figure 1).
Each wire coming from the wall to the existing
thermostat is connected to a terminal point on
3
that thermostat. Each of these terminal points is
usually marked with a code letter as shown in Table
A, Before disconnecting any wires, apply the self
adhesive labels provided to the wire as shown In ‘
Table A. (For example, attach the label marked
W WHITE to the wire which goes to the W or H
terminal on your existing thermostat.)
TYPICAL. HOME THERMOSTATS
Your Hunter thermostat requires three 1.5 volt
batteries. You must replace the batteries
whenever the Low Battery indicator appears on
the display.
IGNORE THE COLOR OF T|-tE WIRES since these do
not always comply with the standard. The number of
wires in your system can be as few as two (for heat
only systems), as many as eight, or any number in
between, if you follow the labeling procedures
correctly, you don’t have to be concerned about how
many wires there are. There is often no terminal
marking on the existing thermostat of two wire, heat
onfy systems. Don't worry, dust connect either of the
wires to the "RED" terminal on your Hunter
thermostat. Then connect the other wire to the
"WHITE" terminal on your thermostat to complete the
circuit.
After labeling wires, disconnect them from the
4
existing thermostat terminals.
Remove existing wallpiate. To make sure wires
5
do not fall back Into wall opening, you may want
to tape them to the wall.
If hole In wall is larger than necessary for wires,
seal this hole up, so no hot or cold air can enter
6
the back of the thermostat from the wall. This air
could cause a false thermostat reading.
