Abstract
An HVAC controller and a method of controlling an HVAC system. In one embodiment, the controller includes: (1) a processor couplable to at least one indoor air quality sensor to receive values therefrom representing at least three levels of indoor air quality and (2) memory coupled to the processor and configured to store a software program capable of causing the processor to control an HVAC system based on magnitudes of the values.
Claims21
An HVAC controller of an HVAC system for an enclosure, comprising:
- a processor coupled to a plurality of indoor air quality sensors of multiple types to receive values therefrom, wherein values received from one of said indoor air quality sensors indicate a type of said one of said indoor air quality sensors, a magnitude of said received values, and a part of said enclosure said received values affect;
- and
- memory coupled to said processor and storing a software program causing said processor to control said HVAC system based on said received values.
A method of controlling an HVAC system for an enclosure, comprising:
- receiving values from a plurality of indoor air quality sensors of multiple types, wherein values received from one of said indoor air quality sensors indicate a type of said one of said indoor air quality sensors, a magnitude of said received values, and a part of said enclosure said received values affect;
- and
- controlling said HVAC system based on said received values.
An HVAC system, comprising:
- an outdoor unit, including:
- at least one compressor stage,
- at least one corresponding condenser fan,
- at least one corresponding refrigerant pressure sensor, and
- at least one condenser coil;
- at least one outside temperature sensor;
- an indoor unit, including:
- at least one evaporator coil,
- at least one indoor blower, and
- at least one expansion valve;
- at least one damper;
- and
- an HVAC controller, including:
- a processor coupled to a plurality of indoor air quality sensors of multiple types, said at least one corresponding refrigerant pressure sensor, and said at least one outside temperature sensor to receive values therefrom, wherein values received from one of said indoor air quality sensors indicate a type of said one of said indoor air quality sensors, a magnitude of said received values, and a part of said enclosure said received values affect;
- and
- memory coupled to said processor and storing a software program causing said processor to control said HVAC system based on said received values.
