4WIRE THERMOSTAT TERMINALS
NOTE: All wiring must comply with local codes and
ordinances. If unsure about household wiring
procedures, call Honeywell Customer Assistance
with your questions Monday-Friday, 7:00 a.m.-
5:30 p.m., Central time, 1-800-468-1502.
Refer to the CT8611 Heat Pump Thermostat
Wiring Guide, form 69-0817, and to the wire
labels you applied when you removed the old
thermostat. Match the letter from your old ther-
mostat wire with the appropriate letter on your
new thermostat. Follow any special instructions
provided in the Wiring Guide. Wire only those
terminals shown with lines connecting them.
Some terminals on the thermostat may not be
used.
For each wire, loosen the terminal screw, slip
the wire beneath its matching terminal, and
tighten the screw.
The shape of the terminal barrier allows straight
or conventional wraparound wiring connections.
NOTE: Keep all wiring restricted to ribbed area
surrounding terminals (Fig. 3) to assure thermo-
stat/subbase contact.
