Install Control Module

A) Find your thermostat cable where it goes into the furnace or air conditioner. This is the

same cable identified in Step 1 and should be the same color and thickness as that

cable.

CAUTION: There may be other cables of similar color connecting other

devices such as a humidifier. Be sure to use the cable that runs back to your

thermostat and not one that is connected to another device. Connecting the

Web Thermostat to the wrong cable can result in electric shock and/or

equipment damage.

B) Mount the Control Module using the following criteria:

◦ Select a location near the furnace where there is sufficient room to mount the

Control Module along where the thermostat cable runs. The thermostat cable will

need to reach both the “Thermostat” and “Furnace/AC” terminals of the Control

Module.

◦ If you will be using the included power supply (see Step 1D), select a location within

4 feet of a power outlet, ideally on the same circuit as the furnace/AC.

◦ Select a location where you can connect to the Internet. If wiring is not convenient,

we suggest using a power line Ethernet adapter that will allow you to make this

connection using your existing power wiring.

C) Splice the Control Module into your existing thermostat cable:

With the furnace and air conditioner power OFF, cut the thermostat wire at a point

where both ends will be able to reach the Control Module mounting location.

Using a wire-stripping tool, strip approximately 2 inches of the outer jacket off both

ends of the thermostat cable, then strip approximately ¼ inch off the end of each of the

thermostat wires.

Attach the wires in the cable coming from the thermostat to the terminals on the LEFT

side of the control module into the connector labeled "Thermostat". Be sure to match

the wire color and terminal designation as identified in Step 1.

Attach the wires in the cable coming from the furnace to the terminals on the RIGHT

side of the control module labeled "Furnace/AC". Be sure to match the wire color and

terminal designation as identified in Step 1.

NOTE: If your system uses separate Rh and Rc wires, be sure to remove the jumper

wire between the Rh and Rc terminals. If your system uses a single Red wire, make

sure the jumper wire between terminals Rh and Rc is installed.
