Turn Off Power to Heating/Cooling System
Remove Old Thermostat
Remove old thermostat but leave wallplate with wires attached.
Identify Wires
If any wires are not attached to your old thermostat or are attached to a
terminal marked C or C1, they will not be connected to your new thermostat.
Wrap the bare metal end of each of these wires with electrical tape, so it
cannot touch and short other wires.
Disconnect wires and remove the old wallplate only after all wires are labeled. Wrap the wires around a pencil to prevent them from falling though the wall opening.
Separate Wallplate from New Thermostat
Mount the new wallplate using the included screws and anchors.
- Remove cover plate.
- Loosen screw (the screw remains captive on wallplate).
- Remove thermostat.
Mount Wallplate
- Mark and drill appropriate mounting holes.
- Insert Plastic anchors.
- Pass wires through opening of wallplate and secure wallplate to the wall using provided screws.
Connect Wires (typical wiring)
- Match each labeled wire with the terminal having the same letter.
- Loosen the terminal screws using a screwdriver, insert the wires, then lighten the screws.
- Push any excess wire back into the wall opening.
Connect Wires (alternate wiring)
If labeled wire does not match any terminal designation, see diagram below.
- Do not use C, X or B. Wrap bare end of wire with electrical tape.
- If wires are connected to both Rh and Rc terminals, remove jumper .
Set Heating Fan Control
Set jumper, on the back of the thermostat, if you have connected a wire to
the G terminal.
HG| Leave the jumper in this factory-set position if you have a gas or oil
furnace.
---|---
HE| Place the jumper to this position if you have an electric furnace.
Incorrect jumper setting: An incorrect setting is noticeable in a gas or oil heating system. When heating starts, you will initially feel cold air coming out of the vents as the fan is running before the furnace has enough time to heat up the air.
Install Batteries
- Pull out the battery cover.
- Install two AA alkaline batteries.
- Reinstall the battery cover.
Install Thermostat onto Wallplate
- Mount the thermostat on the wallplate.
- Tighten the screw and install the cover plate.
Turn Power Back On
Turn the power back on to the heating/cooling system.
