1. If you do not have a ‘C’ wire, you can: 1. use fan wire as ‘C’ wire
(you will not be able to use fan independently) or 2. use an external
power supply.
2. CyberStat does not work with line-voltage baseboard heaters.
3. CyberStat will not work if you have separate Rc and Rh wires. This
limitation does not apply if there is a jumper between Rc and Rh
terminals.

1. Turn off the old thermostat.
2. Turn off power to the heating and cooling system.
3. Remove any locking screw and then remove the face plate.
4. Record the terminal names and corresponding wire colors below.
(Depending on your system, you may not have all the wires listed here)
5. Now remove the wires and the old wall plate.

Install CyberStat

1. Detach the back cover of CyberStat and place it on the wall. Mark
the mounting hole locations with a pencil. You may want to use a level
at this time.
2. Use a #2 Philips head screwdriver to screw-in the provided drywall
anchors at marked locations. If the old thermostat did not use drywall
anchors then most likely there is a wood bracing behind the drywall. In
that case you should skip this step.
Tip: The drywall anchor does not require pre-
drilling. However, making a dimple with the tip of
a screw driver at the marked location will make
the placement more accurate.
3. Mount the back cover on the wall.
4. Connect the wires to the terminals matching the terminal names. See
wiring diagrams for your system on pages 6-13.

Conventional Heat/Cool
6
Wiring option 1 for Conventional Heat and/or Cool system
 Use this wiring option if you have a C wire
 Yellow and green wires are not required for a heat-only system
 White wire is not required for a cool-only system
Notes on C wire:
Make sure that C wire is
connected to C terminal
on the furnace.
You will not get stable
power if C wire is not
connected to C terminal
on the furnace.
A previously unused
wire can be used as C
wire. Simply connect it
to C terminal on furnace
and C terminal on the
thermostat.

Wiring option 2 for Conventional Heat and/or Cool system
 Use this wiring option to re-purpose green wire as C wire
 Re-purposing requires some wiring changes on the furnace side
 With this option, you will not be able to use fan independently

Wiring option 1 for Heat Pump
 Use this wiring option if you have a C wire
 Reversing valve wire is typically orange or blue color
 If there is a conflict between wire color and terminal name, use terminal names
Notes on C wire:
Make sure that C wire is
connected to C terminal
on the air-handler.
You will not get stable
power if C wire is not
connected to C terminal
on the air-handler.
A previously unused
wire can be used as C
wire. Simply connect it
to C terminal on air-
handler and C terminal
on thermostat.
