Install Control Module

A) Find your thermostat cable where it goes into the furnace, air conditioner, or heat

pump. 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) Prepare the thermostat cable:

With the furnace, air conditioner, or heat pump 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.

D) Connect the wiring going to the Thermostat Keypad:

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. If you have more wires

than the four wires labeled on the connector (Red, White, Green, Yellow), bend them

back out of the way and tape to the cable. They will not be used.

Note that you need four wires between the Control Module and Thermostat Keypad

even if you have a heat or cool only system.
