The installation of the iDevices Thermostat Wire Adapter and all wiring must conform to local and national electrical codes. Improper wiring or installation may cause damage to this product, your Thermostat, your HVAC system or your home, and could result in personal injury.
The iDevices Thermostat Wire Adapter is intended to share two Thermostat signals over one wire, so that you can add a C wire to a system that doesn’t currently have one. Your system will need at least 3 physical wires between the HVAC control board and the Thermostat, as well as an accessible C/Common terminal on the HVAC control board or transformer to connect to.
The iDevices Thermostat Wire Adapter should be installed in or near the HVAC system control board or furnace, or another dry, indoor location. Find a location with easy access to the wires that run between the HVAC unit and the Thermostat. If needed, you can use two #8 screws (not included) to mount the wire adapter to a convenient surface.
WIRING REQUIREMENTS
- Acceptable Wire: 24-18AWG
- Wire Length (total wire length between HVAC system and Thermostat): 18 AWG: 195 feet 24 AWG: 65 feet
- All wires and connections should conform to applicable local and national electrical codes.
Note: The Wire Adapter should not be used to “share” either the R (or RC/RH) wire or the C wire. Both the R wire for the system and the C wire must each be separate, physical wires, or damage to the system or Thermostat, or unintended/undesirable system operation may result.
