Abstract

Disclosed are exemplary embodiments of system controllers and methods for controlling a climate control system. In an exemplary embodiment, a wireless-enabled climate system controller receives power from one or more power sources. A processor and memory of the controller are configured to monitor power budget availability from the power source(s) for performance of wireless communication by the climate control system controller. The processor and memory are further configured to determine power budget requirements for combinations of communication modes in which the controller is capable of performing wireless communication, and based on the monitoring and determining, configure the controller to perform wireless communication using a selected one of the communication mode combinations. A thermostat can optimize levels of operation and battery life, by determining an appropriate operating mode that could offer the most functionality while not exceeding the power budget available.
