Disclosed are exemplary embodiments of apparatus and methods for facilitating installation and/or connection of controllers such as thermostats. In an exemplary embodiment, an apparatus for facilitating installation and/or connection of a controller in a climate control system generally includes a communication device configured to execute software instructions to receive user input describing a wire arrangement where the controller is to be installed for use in the climate control system. Based on the user input, the communication device identifies a configuration of the climate control system and specifies wiring connections between the wire arrangement and controller.

Facilitating installation of a controller and/or maintenance of a climate control system

A method of controlling a heating system including at least a first stage heat pump and a second stage auxiliary heater, and a control that implements the method. The control shuts off the first stage heat pump during cold outside temperatures without the need to directly sense the outside temperature. The method includes selectively turning on the first stage heat pump or the second stage auxiliary heater based upon a measure of the amount of time at least one of the stages was on verses the time neither of the stages was on. This can be implemented with a counter that increases when neither the heat pump nor the auxiliary heater is on, and that decreases when either the heat pump or the auxiliary heater is on.
