First Claim
Patent Images
1. An HVAC controller for controlling one or more components of an HVAC system of a building, the HVAC controller comprising:
- a memory;
a wireless transceiver for wirelessly sending and receiving data over a wireless local area network of the building;
a controller configured to provide control signals to the one or more components of the HVAC system;
the controller further configured to connect the HVAC controller to the wireless local area network of the building via the wireless transceiver, and once connected, determine if at least one mobile wireless device known to the HVAC controller as corresponding to a known user'"'"'s mobile device is currently wirelessly connected to the wireless local area network or not, wherein;
if at least one mobile wireless device known to the HVAC controller as corresponding to a known user'"'"'s mobile device is currently wirelessly connected to the wireless local area network, the controller is configured to operate the HVAC system in accordance with a predetermined schedule comprising an occupied time period and a sleep time period, wherein during the occupied time period the controller controls the HVAC system in accordance with an occupied temperature setpoint, and during the sleep time period the controller controls the HVAC system in accordance with a sleep temperature setpoint; and
if no mobile wireless device known to the HVAC controller as corresponding to a known user'"'"'s mobile device is currently wirelessly connected to the wireless local area network, the controller is configured to operate the HVAC system in accordance with an unoccupied temperature setpoint.
