Wire Labeling - Hunter 44008-01 Owner's Manual

Wire Labeling

■ Each wire coming from the wall to the existing
thermostat is connected to a terminal point on that
thermostat. Each of these terminal points is usually
marked with a code letter as shown in Table A on
page 11.
■ IMPORTANT! BEFORE DISCONNECTING ANY
WIRES, APPLY THE SELF-ADHESIVE LABELS
PROVIDED TO THE WIRE AS SHOWN IN TABLE A
ON PAGE 11. (For example, attach the label marked
W to the wire that goes to the W or H terminal on
your existing thermostat.) IGNORE THE COLOR OF
THE WIRES since these do not always comply with
the standard.
IMPORTANT!
If wires marked Y & C are both present, C may be a
Common wire and should not be used. If you have
a wire marked C, do not connect it to any terminal.
This wire is used only for non-battery powered
thermostats.
■ After labeling wires, disconnect them from the
existing thermostat terminals.
■ Remove existing wallplate. To make sure wires 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 so that no hot or cold air can enter the back
of the thermostat from the wall. This air could cause
a false thermostat reading.
