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.
◦
Select a location within 6 feet of a power outlet, ideally on the same circuit as the
furnace/AC, or heat pump.
◦
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.
