Installing and Wiring the Thermostat
3
Remove the base plate from the wall and drill two or three holes at the marked
locations: for drywall, drill 3/16” holes; for plaster, drill 7/32” holes.
4
Gently tap the wall anchors (included in the packaging) into the drilled holes until
they are flush with the wall.
5
Pull the wires through the base plate and position the base plate over the screw holes.
6
Attach the base plate to the wall using three 1" screws (included in the packaging).
Wiring the Base Plate Terminals
This section describes how to wire the base plate terminals. Use the instructions in this
section and refer to:
Table 2
and
Figure 1 on page 5
to wire the IMT base plate terminals for Fuel
Burner HVAC. A Fuel Burner typically burns fossil fuel like oil or gas and does
not have a wire used as a reversing valve.
Table 2
and
Figure 2 on page 6
to wire the IMT base plate terminals for Heat
Pump HVAC. A Heat Pump configuration always has a wire used to control a
reversing valve.
Refer to the labels you placed on the wires when you removed the existing thermostat.
See
page 1
.
Table 2
lists the standard HVAC terminal label required to support the single-stage
and dual-stage Fuel Burner and Heat Pump applications.
Note
H
Some newer Heat Pumps use traditional Fuel Burner wiring schemes without a
Reversing Valve (RV). Therefore, you may have to use a Fuel Burner wiring
scheme to control your Heat Pump. Refer to your Heat Pump manual for wiring
details.
You must know the type of Reversing Valve in your heat pump. Refer to your Heat
Pump manual for more information.
