Abstract:
1. A method of controlling an energy management system having a plurality of zones respectively controlled by a plurality of thermostats, the method comprising: receiving, via a touch screen of a first thermostat, a command to display set points of one or more zones of a building, the first thermostat being one of the plurality of thermostats, each controlling one or more zones of a building; causing the touch screen of the first thermostat to display the set points of the one or more zones; receiving, via the touch screen of the first thermostat, an override command and override set points for a selected zone of the one or more zones to temporarily alter the set points of the selected zone; transmitting the received override set points to a central site controller for processing; determining, at the central site controller, whether the override set points are within preset allowable parameters; controlling, with the second thermostat, the temperature of a zone associated with the second thermostat according to the override set points; determining whether a predetermined amount of time has elapsed since the override set points were sent to the second thermostat, and if so, sending the currently programmed set points to the second thermostat; and controlling, with the second thermostat, the temperature of the zone associated with the override set points according to the currently programmed set points; generating and sending, via the site controller, an override request deny signal if the requested override set points are not within preset allowable parameters; receiving, via the first thermostat, the override request deny signal from the site controller; and displaying, on the touch screen a symbol representative of the override request deny signal; wherein said steps of receiving a command to display set points, causing the touch screen to display the set points, receiving an override command and override set points, transmitting the received override set points, determining whether the override set points are within allowable parameters, merging override set points, sending the override set points, controlling the temperature, and determining whether an amount of time has elapsed are conducted by one or more particular machines comprising one or more processors and memory, respectively.
