Abstract
Methods, devices and systems for coupling an HVAC controller to an HVAC system are provided. In several embodiments, a sub-base is provided allowing an HVAC controller to be coupled to a printed wire board to allow, in some cases, modification of the HVAC controller function. The sub-base may include a plurality of terminals, each terminal having a contact mating feature for receiving a pin of an HVAC controller, a terminal block location for receiving an end of a wire, and a transformation pin-out adapted to couple to a printed wire board, with the contact mating feature, the terminal block location, and the transformation pin-out being electrically coupled together. In one embodiment, an HVAC controller is modified to allow a controller adapted for use with a single fuel system to control dual fuel system.
