Wiring
Terminal Designations
This thermostat is shipped from the factory to operate a conventional
heating and cooling system. This thermostat may also be configured for a heat
pump system. See the “heat pump” configuration step on page 14 of this manual
to configure the thermostat for heat pump applications.
Terminal| 2 Heat 2 Cool Conventional System| 2 Heat 1
Cool Heat Pump System| 3 Heat 2 Cool Heat Pump
System
---|---|---|---
RC| 24 VAC power (Cooling)| 24 VAC power (Cooling)| 24 VAC power

G| Fan relay| Fan relay| Fan relay
W/E| First stage of heat| Emergency Heat| First stage of auxiliary heat
Y| First stage of cool| First stage of heat & cool| First stage of heat

Y2| Second stage of cool| N/A| Second stage of heat & cool
W2| Second stage of heat| Auxiliary heat| Second stage of auxiliary heat
Wiring Notes
-
Common wire
The C (common wire) is optional when the thermostat is powered by batteries. -
Wire Specifications
Use 18- to 22-gauge thermostat wire. Shielded wire is not required. -
Notes:
In many heat pump systems without emergency heat relay, a jumper can be installed between E and W2 to the turn thermostat into a single stage control for Emergency Heat Operation.
Installation Tip: Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues. Max Torque = 6in/lbs.
Wiring Diagrams
- Power supply
- Factory-installed jumper. Remove only when installing on 2-transformer systems.
- Use either O or B terminals for reversing valve.
- Optional 24 VAC commom connection when thermostat is used in battery power mode.
Installer Setup Menu

Programming Notes
Differential Setting
The second stage will turn ON at 2x the differential setting and OFF at 1x the
differential setting. For example, if the differential setting is 0.5° for
heating and the thermostat is set at 70°F, the first stage will turn on at
69.5°F. The second stage will turn on at 69°F and turn off at 69.5°F. If the
third stage is used, the third stage will turn on at 68.5°F and turn off at
69°F.
Keypad Lockout
The installer can activate a keypad lockout after exiting Tech Setup. Default

Notes:
- Auto Changeover: In Auto mode, users can toggle between Auto Heat or Auto Cool by pressing System only when the current mode has reached its temperature set point. To switch out of Auto mode, hold down System. To return to Auto mode, toggle the System key to Auto.
- Programmable Fan: The programmable fan feature will run the fan continuously during any time period it is programmed to be on. This is the best way to keep the air circulated and to eliminate hot and cold spots in your building.
- Reminders: Once a Reminder has been turned on and set, the elapsed time can be checked by navigating the Tech Setup step. The time can be reset by pressing and holding the third button from the left for 3 seconds. Resetting an expired Reminder can be done by pressing and holding the 3rd button from the left for 3 seconds.
