Abstract
A thermostat providing modulated or analog control of valves or dampers of an air management system. This permits operating a single cooling or heating stage with partially open valves or dampers as needed, since one full stage that is either fully on or off may not be easy to manage for effective air management of a particular type of building, zone or facility. The thermostat may also provide non-modulated control of multi-stage cooling and heating systems. The thermostat may even be used to control a modulated system having more than one stage of cooling or heating.
Claims31
A thermostat system comprising:
- a processor having a user interface;
- and
- a program, in the processor, having an at least one configuration for an air management system, the at least one configuration comprising:
- an air management system identification;
- a listing of zones for the air management system;
- parameter settings for each zone;
- schedules of the parameter settings;
- a modulated control for a plurality of heating stages for at least one zone;
- a modulated control for a plurality of cooling stages for at least one zone;
- and
- a modulated control for a simultaneous operation of a heating device and a cooling device.
A thermostat system comprising:
- a plurality of thermostats;
- and
- wherein each thermostat of the plurality of thermostats comprises at least one configuration for an air management system, the at least one configuration comprising:
- an air management system identification;
- a listing of zones for the air management system;
- parameter settings for each zone;
- schedules of the parameter settings;
- modulated controls for a plurality of heating stages for at least one zone;
- and
- modulated controls for a plurality of cooling stages for at least one zone.
A thermostat system for controlling at least part of an HVAC system, wherein the HVAC system includes three or more heating and/or cooling stages, the thermostat comprising:
- a first modulated output coupled to a first stage of the three or more stages and providing a first modulated variable output for controlling the first stage;
- a second modulated output coupled to a second stage of the three or more stages and providing a second modulated variable output for controlling the second stage at the same dine as the first modulated output provides the first modulated variable output for controlling the first stage;
- and
- a discrete on/off output coupled to a third stage of the three or more stages for providing a discrete on/off output for controlling the third stage.
A thermostat system for controlling at least part of an HVAC system, wherein the HVAC system includes two or more heating stages and one or more cooling stages, the thermostat comprising;
- a first modulated output coupled to a first heating stage and providing a first modulated variable output for controlling the heat output of the first heating stage;
- a second modulated output coupled to a second heating stage and providing a second modulated variable output for controlling the heat output of the second heating stage at the same time as the first modulated output provides the first modulated variable output for controlling the heat output of the first heating stage;
- and
- a discrete on/off output coupled to a cooling stage fir providing a discrete on/off output for controlling the cooling stage.
