Abstract:
Methods and systems, including computer programs encoded on computer storage media, for using a power handling thermostat, the method including determining that (i) power to a thermostat is not available from line power of a ventilation system and (ii) power is available from a supercapacitor in the thermostat, drawing power from the supercapacitor instead of from the line power, determining that power is no longer available from the supercapacitor, in response to determining that power is no longer available from the supercapacitor, drawing power from a battery in the thermostat instead of from the supercapacitor, determining that power to the thermostat is available from the line power of the ventilation system, and in response to determining that power to the thermostat is available from the line power of the ventilation system, drawing power from the line power of the thermostat.
