Replacement Thermostat Wiring
If you are replacing a thermostat, make
note of the terminal connections on the
thermostat that is being replaced. In some
cases the wiring connections will not be
color coded. For example, the green wire
may not be connected to the Gterminal.
Loosen the terminal block screws. Insert
wires then retighten terminal block screws.
Place nonammable insulation into wall
opening to prevent drafts.

3.
This thermostat requires a 24V common
wire to the C terminal.
4.
Caution:
Electrical Hazard
All components of the control system
and the thermostat installation must
conform to Class II circuits per the
NEC Code.
Warning:
Do not overtighten terminal block screws, as this can damage the terminal block.
A damaged terminal block can keep the thermostat from tting on the subbase
correctly or cause system operation issues.
Installation Tip Max Torque = 6in-lbs.
Failure to disconnect the power
before beginning to install this
product can cause electrical shock or
equipment damage.

If using in Heat Pump without Auxiliary or Emergency heat application,
please see wiring diagram on previous page.
Note: Devices such as a oat switch that mechanically break circuits should be installed
so that they break the control wire (Y) not the power (R). Interrupting the power circuit
will shut o power to the thermostat completely and not allow it to operate.
To enter tech setup:
1. Press and hold the + and - buttons for 3 seconds.

Temperature swing, sometimes called dierential or cycle rate, can be
customized for this individual application. For most applications choose a swing
setting that is as wide as possible without making the occupants uncomfortable.
