Description

WiFi thermostats that communicate with smart home systems like Amazon Alexa and Apple HomeKitTM often need a constant 24V AC power source, typically called a C-wire. The LUX Power Bridge allows homes with 3 and 4 wire systems to take advantage of the benefits of smart thermostats without requiring a new wires to be installed between the furnace equipment and the thermostat. If a C-wire is not present at the thermostat location, adding the LUX Power Bridge can provide the additional C-wire in most 3 or 4 wire heating or cooling systems. The LUX Power Bridge can be used to provide a 24V C-Wire to any LUX thermostat which is capable of accepting 24V System Power from the equipment (*IF SYSTEM TYPE PERMITS USAGE OF POWER BRIDGE).

Not compatible with all system types.
Must have forced-air heating or cooling.
Must have a fan "G" wire at existing thermostat location.
Does not work with 2-wire heating or cooling applications.
Requires mild wiring ability and installs inside heating/cooling equipment.
