Venstar ACC0410 Add-A-Wire Accessory for 24 VAC Thermostats (4 to 5 Wires), White

In applications where additional wiring cannot be run to your programmable digital thermostat, the Add-A-Wire accessory can be used to add a wire to the thermostat. The accessory can also be used for fixing a broken wire, to make one thermostat work like two, to add cooling to a heat-only system, or to add a common wire to a 4-wire system.

Please note that the green and yellow wires of the Diode "Y" may not be connected to the R or C terminal of the thermostat. (The function of a diode is to allow current in one direction and to block current in the opposite direction.)

This accessory works with the Venstar 1-Day Programmable Digital Thermostat, the 7-Day Programmable Digital Thermostat, and the 7-Day Programmable Thermostat, Dual Fuel (each sold separately).
