In applications where additional wiring cannot be run to your programmable digital thermostat, the Briidea 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. Allows 5 wire thermostats to use only 4 wires, also allows 5 wires to work like 6 wires. Includes yellow, green, blue wire splice and 2 wire nuts. For use with all 24V AC systems. Briidea provides friendly customer service and a 12-month warranty on the product.
