Wire Labeling - Hunter Thermostat Installation Manual And User's Manual

Wire Labeling

■ Each wire coming from the wall to the existing thermo-
stat 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 the next page.
■ IMPORTANT! BEFORE DISCONNECTING ANY WIRES, AP-
PLY THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE
AS SHOWN IN TABLE A and B ON PAGES 2-. (For ex-
ample, 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.
■ 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.
