MAKING 5 WIRES WORK when 6 are required
(without the optional Add-A-Wire accessory)
• If you have an all-electric heat system with air conditioning, this
method is not an option. You must either pull new wire or use the
optional Add-A-Wire accessory (ACC-0410).
• If you have a multi stage system that requires 6 wires, and you
would like install the Venstar ColorTouch using only 5 wires, follow
the directions below. You will need a screwdriver along with a 3” or
4” long piece of thermostat wire to use as a jumper.
