An HVAC controller with a simplified and/or lower cost user interface. In one illustrative embodiment, the HVAC controller includes two switches, a movable member, and a plurality of detents. The detents are configured to cause the two switches to be switched in a sequence when the movable member is moved. In some cases, a controller is coupled to the two switches, and may change an HVAC control parameter based on the switch sequence.

HVAC controller

Remote-control system comprising a main unit and, connected at a distance via a pair of conductors to the main unit, an operating unit which comprises a series circuit of a number of diodes connected between the conductors of the conductor pair, a number of switches connected parallel to one or more of the diodes, and a signalling circuit. The main unit provides signalling corresponding to the certain current. In particular the certain current is determined by the state of the switches.
