* Remove factory installed jumper for two transformer systems.
The THP9045A1023 Wire Saver module is used on heat/cool systems when you only have four wires at the thermostat
and you would like the thermostat to be powered with a common wire. Use the K terminal in place of the Y and G terminals
on conventional or heat pump systems to provide control of the fan and the compressor through a single wire—the
unused wire then becomes your common wire. See THP9045 instructions for more information.
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before wiring.
All wiring must comply with local electrical codes and
ordinances. See Fig. 314–353.
1. Select wiring diagram that corresponds with system
type and the equipment being installed (using the
EIM or wiring the thermostat directly to the HVAC
equipment).
2. Loosen the screws for the appropriate terminals.
Insert wires in the terminal block under the loosened
screw. See Fig. 312 and 313.
3. Securely tighten each screw.
4. Push excess wire back into the hole.
5. Plug the hole with nonflammable insulation to pre-
vent drafts from affecting the thermostat.
6. See Fig. 314–338 for typical wiring hookups.
