Swing Setting Tip
Temperature swing, sometimes called differential 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.

Replacement Thermostat Wiring
1.
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 G terminal.
2.
Loosen the terminal block screws. Insert
wires then retighten terminal block screws.
3.
Place nonflammable insulation into wall
opening to prevent drafts.
4.
This thermostat requires a 24V common
wire to the C terminal.
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.
Wiring Chart
For all systems, the following terminals are wired according to whether you have a
single or dual transformer system as shown:

DUAL

*FAILURE TO REMOVE PROVIDED JUMPER ON DUAL TRANSFORMER INSTALLATIONS COULD CAUSE SEVERE DAMAGE TO HVAC SYSTEMS

Note: Devices such as a float 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 off power to the thermostat completely and not allow it to operate.
If using in Heat Pump without Auxiliary or Emergency heat application,
please see wiring diagram on previous page.
