Abstract

A multisystem controller communicatively coupled to a first HVAC system and a second HVAC system includes a memory configured to store a first temperature change, a second temperature change, and correction factors and a processor configured to access the first temperature change and the second temperature change, identify, based on the first temperature change, the first HVAC system as regulating the temperature of the downstairs space, and to identify, based on the second temperature change, the second HVAC system as regulating the temperature of the upstairs space. The processor is configured to receive a user input comprising a first temperature setpoint, and, in response, generate, based on the first temperature setpoint, the correction factors, and the identification, a second temperature setpoint, and further to instruct the first HVAC system to operate based on the first temperature setpoint and the second HVAC system to operate based on the second temperature setpoint.

Dependent claims

A system, comprising:

a first heating, ventilation, and air conditioning (HVAC) system configured to regulate temperature of one of a downstairs space or an upstairs space of a multistory building;
a second HVAC system configured to regulate temperature of one of the downstairs space or the upstairs space of the multistory building, wherein each of the first HVAC system and the second HVAC is configured to regulate the temperature of a different one of the downstairs space or the upstairs space of the multistory building;
and
a multisystem controller communicatively coupled to the first HVAC system and the second HVAC system, the multisystem controller, comprising:
a memory configured to store a first temperature change associated with the first HVAC system, a second temperature change associated with the second HVAC system, and a set of correction factors;
and
a processor communicatively coupled to the memory and configured to:
access the first temperature change associated with the first HVAC system;
access the second temperature change associated with the second HVAC system;
identify, based at least in part on the first temperature change, the first HVAC system as regulating the temperature of the downstairs space;
identify, based at least in part on the second temperature change, the second HVAC system as regulating the temperature of the upstairs space;
receive a user input comprising a selection of a first temperature setpoint to which the first HVAC system is to regulate the temperature of the downstairs space;
and
in response to receiving the user input:
generate, based at least in part on the first temperature setpoint, the set of correction factors, and the identification that the second HVAC system is regulating the temperature of the upstairs space, a second temperature setpoint to which the second HVAC system is to regulate the temperature of the upstairs space;
and
instruct the first HVAC system to operate based at least in part on the first temperature setpoint and the second HVAC system to operate based at least in part on the second temperature setpoint.

A method, comprising:

accessing a first temperature change associated with a first heating, ventilation, and air conditioning (HVAC) system, wherein the first HVAC system is configured to regulate temperature of one of a downstairs space or an upstairs space of a multistory building;
accessing a second temperature change associated with a second HVAC system, wherein the second HVAC system is configured to regulate temperature of one of the downstairs space or the upstairs space of the multistory building, and wherein each of the first HVAC system and the second HVAC is configured to regulate the temperature of a different one of the downstairs space or the upstairs space of the multistory building;
identifying, based at least in part on the first temperature change, the first HVAC system as regulating the temperature of the downstairs space;
identifying, based at least in part on the second temperature change, the second HVAC system as regulating the temperature of the upstairs space;
receiving a user input comprising a selection of a first temperature setpoint to which the first HVAC system is to regulate the temperature of the downstairs space;
and
in response to receiving the user input:
generating, based at least in part on the first temperature setpoint, a set of correction factors, and the identification that the second HVAC system is regulating the temperature of the upstairs space, a second temperature setpoint to which the second HVAC system is to regulate the temperature of the upstairs space;
and
instructing the first HVAC system to operate based at least in part on the first temperature setpoint and the second HVAC system to operate based at least in part on the second temperature setpoint.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

access a first temperature associated with a first heating, ventilation, and air conditioning (HVAC) system at a first point in time and a second temperature associated with the first HVAC system at a second point in time, wherein the first HVAC system is configured to regulate temperature of one of a downstairs space or an upstairs space of a multistory building;
access a first temperature change associated with a first heating, ventilation, and air conditioning (HVAC) system, wherein the first HVAC system is configured to regulate temperature of one of a downstairs space or an upstairs space of a multistory building;
access a second temperature change associated with a second HVAC system, wherein the second HVAC system is configured to regulate temperature of one of the downstairs space or the upstairs space of the multistory building, and wherein each of the first HVAC system and the second HVAC is configured to regulate the temperature of a different one of the downstairs space or the upstairs space of the multistory building;
identify, based at least in part on the first temperature change, the first HVAC system as regulating the temperature of the downstairs space;
identify, based at least in part on the second temperature change, the second HVAC system as regulating the temperature of the upstairs space;
receive a user input comprising a selection of a first temperature setpoint to which the first HVAC system is to regulate the temperature of the downstairs space;
and
in response to receiving the user input:
generate, based at least in part on the first temperature setpoint, a set of correction factors, and the identification that the second HVAC system is regulating the temperature of the upstairs space, a second temperature setpoint to which the second HVAC system is to regulate the temperature of the upstairs space;
and
instruct the first HVAC system to operate based at least in part on the first temperature setpoint and the second HVAC system to operate based at least in part on the second temperature setpoint.
