Thermostat for controlling operation of a heating,ventilation, and air conditioning (hvac) system

Abstract

Embodiments of the disclosure describe systems and methods for controlling operation of a heating, ventilation, and air conditioning (HVAC) system by a thermostat. The thermostat comprises a set of wires. The method comprises determining an operation to be performed by the HVAC system based on at least one of a user input or one or more parameters associated with an indoor area. The method further comprises transmitting, to the HVAC system via the set of wires, an HVAC signal indicative of the operation to be performed. At least one wire of the set of wires is configured to communicate power signals and data signals associated with the HVAC signal. The method further comprises causing the HVAC system to perform the operation based on the transmitted HVAC signal. The set of wires comprises a common (C) line, a power line (R), and an outdoor activation (Y) line.

We claim: 
     
         1 . A thermostat to control operation of a heating, ventilation, and air conditioning (HVAC) system, the thermostat comprising:
 a set of wires;   a memory; and   one or more processors communicatively coupled to the memory and the set of wires, the one or more processors being configured to:
 determine an operation to be performed by the HVAC system based on at least one of a user input or one or more parameters associated with an indoor area, the indoor area being associated with the thermostat and the HVAC system; 
 transmit, to the HVAC system via the set of wires, an HVAC signal indicative of the operation to be performed, wherein at least one wire of the set of wires is configured to communicate power signals and data signals associated with the HVAC signal; and 
 cause the HVAC system to perform the operation based on the transmitted HVAC signal, 
 wherein the set of wires comprises a common (C) line, a power line (R), and an outdoor activation (Y) line. 
   
     
     
         2 . The thermostat of  claim 1 , wherein the one or more processors are configured to:
 monitor the one or more parameters associated with the indoor area;   receive the user input indicative of a command corresponding to the operation to be performed; and   generate the HVAC signal based on at least one of the monitored environmental parameters and the received user input.   
     
     
         3 . The thermostat of  claim 1 , wherein:
 the at least one wire of the set of wires is associated with a powered state and an unpowered state, and   the at least one wire is configured to communicate the data signals in the powered state and in the unpowered state.   
     
     
         4 . The thermostat of  claim 1 , wherein:
 the HVAC system comprises a first HVAC unit and a second HVAC unit, and   the one or more processors are configured to transmit the data signals to the first HVAC unit and the second HVAC unit via the Y line.   
     
     
         5 . The thermostat of  claim 4 , wherein the one or more processors are configured to simultaneously transmit the HVAC signal to the first HVAC unit and the second HVAC unit. 
     
     
         6 . A method for controlling operation of a heating, ventilation, and air conditioning (HVAC) system by a thermostat, the thermostat comprising a set of wires, the method comprising:
 determining an operation to be performed by the HVAC system based on at least one of a user input or one or more parameters associated with an indoor area, the indoor area being associated with the thermostat and the HVAC system;   transmitting, to the HVAC system via the set of wires, an HVAC signal indicative of the operation to be performed, wherein at least one wire of the set of wires is configured to communicate power signals and data signals associated with the HVAC signal; and   causing the HVAC system to perform the operation based on the transmitted HVAC signal,   wherein the set of wires comprises a common (C) line, a power line (R), and an outdoor activation (Y) line.   
     
     
         7 . The method of  claim 6 , further comprising:
 monitoring the one or more parameters associated with the indoor area;   receiving the user input indicative of a command corresponding to the operation to be performed; and   generating the HVAC signal based on at least one of the monitored environmental parameters and the received user input.   
     
     
         8 . The method of  claim 6 , wherein:
 the at least one wire of the set of wires is associated with a powered state and an unpowered state, and   the at least one wire is configured to communicate the data signals in the powered state and in the unpowered state.   
     
     
         9 . The method of  claim 6 , wherein:
 the HVAC system comprises a first HVAC unit and a second HVAC unit, and   the one or more processors are configured to transmit the data signals to the first HVAC unit and the second HVAC unit via the Y line.   
     
     
         10 . The method of  claim 9 , further comprising simultaneously transmitting the HVAC signal to the first HVAC unit and the second HVAC unit.
