Methods systems and tools for determining a wiring configuration for an hvac controller

A computer readable medium having stored thereon in a non-transitory state a set of instructions executable by a controller, the set of instruction causing the controller to execute a method comprising:

• receiving a number of user inputs from a user via a user interface, the number of user inputs identifying:
• a current wiring configuration of a current HVAC controller;
• a replacement HVAC controller that is to replace the current HVAC controller;
• determining a new wiring configuration for the replacement HVAC controller based, at least in part, on the current wiring configuration of the current HVAC controller as well as the replacement HVAC controller that is to replace the current HVAC controller;
• and
• outputting the new wiring configuration to the user.

A system comprising:

• a communications port for communicating with a user interface;
• a memory storing wiring configurations for each of a plurality of current HVAC controllers, along with one or more corresponding new wiring configurations for each of a plurality of replacement HVAC controllers;
• and
• a controller operatively coupled to the communications port and the memory, the controller programmed to display on the user interface a plurality of wiring terminal labels and at least two replacement HVAC controllers available for selection by a user via the user interface, wherein in response to receiving a selection of a replacement HVAC controller as well as a selection of two or more wiring terminal labels indicative of the current wiring configuration of the current HVAC controller, the controller is configured to reference the memory and determine a new wiring configuration for the selected replacement HVAC controller based, at least in part, on the selected two or more wiring terminal labels and the selected replacement HVAC controller.
