Wiring

NOTE: Please note the wire colours and terminal letters they are attached to on the old thermostat.

WIRING COLOURS ARE NOT ALWAYS STANDARDIZED, IT IS VERY IMPORTANT TO LABEL ALL WIRES ACCORDING TO THE LETTER DESIGNATION ON YOUR OLD THERMOSTAT. (The wires are usually designated ‘W’, ‘Y’, ‘G’, ‘RH’, ‘RC’, ‘B’, ‘O’ or humidistat wires)

• Disconnect wires from old thermostat or sub-base.

• As you disconnect each wire, use masking tape to label it with the old terminal designation.

• Take care not to let the wires fall back into the wall or let the ends of the wires touch one another.

• If there is an extra wire that is not connected to your old thermostat, then you won’t need to connect it to the new thermostat.

Humidifier Wiring

• To wire a humidifier, the 2 wires connecting the original humidistat need to be connected to the 2 terminals marked 'H1' and 'H2' on the thermostat.

• The original humidistat should be removed or set to 'OFF' position.

• The 2 humidifier control terminals 'H1' and 'H2' are electrically isolated from the Heat / Cool terminals.

• 'H1' and 'H2' terminals are non-polarized, and there is no function difference between 'H1' and 'H2'.

Installation

Page 12

Connecting the Wires to the Terminals Connect the previously labeled wires to the corresponding terminals, matching the designations. Use a screwdriver to loosen the terminal, wrap the wires around the terminal, and then tighten to securely fasten the wires. Make sure the wires do not touch or short-circuit with other terminals.

• Depending on your heating/cooling equipment, you may need to connect between 2 and 7 wires.

• If you have 2 ‘R’ wires, then connect each wire to its corresponding terminal, and remove the JUMPER between the RC and RH terminals.

• If you are unsure of the connections, please consult a certified HVAC contractor for the correct installation of your thermostat.
