HVAC boiler controller
View Patent ↗A heating, ventilation, and air conditioning (HVAC) boiler controller is described herein. One HVAC boiler controller includes a memory and a processor configured to execute executable instructions stored in the memory to receive a weather forecast for an area in which the boiler of the HVAC system is located, receive a current outdoor temperature, determine a set point of the boiler based, at least in part, on the received weather forecast and the received current outdoor temperature, and adjust the set point of the boiler to the determined set point.
1. A controller for a boiler of a heating, ventilation, and air conditioning (HVAC) system, comprising:
a memory; and
a processor configured to execute executable instructions stored in the memory to:
receive, via a network, a current outdoor temperature for an area in which the boiler of the HVAC system is located;
determine that a failure of a temperature sensor of the HVAC system has occurred;
in response to determining that the failure of the temperature sensor of the HVAC system has occurred, determine a new set point for the boiler based, at least in part, on the current outdoor temperature received via the network, and not based on a current outdoor temperature sensed by the temperature sensor of the HVAC system; and
adjust a set point for the boiler to the new set point.
2. The controller of claim 1 , wherein the processor is configured to execute the instructions to:
receive, from a server via the network, a weather forecast for the area in which the boiler of the HVAC system is located; and
determine the new set point for the boiler based, at least in part, on the weather forecast received from the server via the network.
3. The controller of claim 1 , wherein the temperature sensor of the HVAC system is directly connected to the controller.
4. The controller of claim 1 , wherein the processor is configured to execute the instructions to receive the current outdoor temperature solely from a weather forecast service.
5. The controller of claim 1 , wherein the processor is configured to execute the instruction to receive the current outdoor temperature via the network from a boiler of an additional HVAC system located in the area.
6. The controller of claim 1 , wherein the processor is configured to execute the instructions to:
receive the current outdoor temperature sensed by the temperature sensor of the HVAC system; and
determine the new set point for the boiler by replacing the current outdoor temperature sensed by the temperature sensor with the current outdoor temperature received via the network.
7. The controller of claim 1 , wherein the processor is configured to execute the instruction to receive, from a server via the network, the current outdoor temperature of a boiler of an additional HVAC system located in the area.
8. The controller of claim 1 , wherein to determine that the failure of the temperature sensor of the HVAC system has occurred, the processor is configured to execute the instruction to determine that a fault or malfunction of the temperature sensor of the HVAC system has occurred.
9. The controller of claim 1 , wherein to determine that the failure of the temperature sensor of the HVAC system has occurred, the processor is configured to determine that the HVAC system does not have a local outdoor temperature sensor installed.
10. A controller for a boiler of a heating, ventilation, and air conditioning (HVAC) system, comprising:
a memory; and
a processor configured to execute executable instructions stored in the memory to:
receive a weather forecast for an area in which the HVAC system is located, wherein the weather forecast is received from a server via a network;
determine that a current outdoor temperature sensed at the location of the HVAC system is inaccurate;
determine a new set point for the boiler based on the weather forecast received from the server via the network in response to determining that the current outdoor temperature sensed at the location of the HVAC system is inaccurate; and
adjust a set point for the boiler to the new set point.
11. The controller of claim 10 , wherein to determine the current outdoor temperature sensed at the location of the HVAC system is inaccurate, the processor is configured to execute the instructions to:
compare the current outdoor temperature sensed at the location of the HVAC system and a current outdoor temperature included in the weather forecast received from the server via the network.
12. The controller of claim 10 , wherein the processor is configured to execute the instructions to determine the new set point for the boiler based, at least in part, on an outdoor reset curve of the boiler.
13. The controller of claim 10 , wherein the current outdoor temperature sensed at the location of the HVAC system is sensed by a local outdoor temperature sensor at the location of the HVAC system.
14. The controller of claim 10 , wherein the weather forecast includes an indication that an outdoor temperature in the area in which the HVAC system is located will increase above a particular temperature.
15. The controller of claim 10 , wherein the weather forecast includes an indication that an outdoor temperature in the area in which the HVAC system is located will increase by more than a particular amount within a particular amount of time.
16. A controller for a boiler of a heating, ventilation, and air conditioning (HVAC) system, comprising:
a memory; and
a processor configured to execute executable instructions stored in the memory to:
receive a weather forecast for an area in which the HVAC system is located, wherein the weather forecast is received from a server via a network;
determine that a failure of a temperature sensor of the HVAC system has occurred;
in response to determining that the failure of the temperature sensor of the HVAC system has occurred, determine a new set point for the boiler based, at least in part, on the weather forecast received from the server via the network; and
adjust a set point for the boiler to the new set point.
17. The controller of claim 16 , wherein the weather forecast includes an indication that an outdoor temperature in the area in which the HVAC system is located will increase above a particular temperature.
18. The controller of claim 16 , wherein the weather forecast includes an indication that an outdoor temperature in the area in which the HVAC system is located will increase by more than a particular amount within a particular amount of time.
19. The controller of claim 16 , wherein to determine that the failure of the temperature sensor of the HVAC system has occurred, the processor is configured to execute the instruction to determine that a fault or malfunction of the temperature sensor of the HVAC system has occurred.
20. The controller of claim 16 , wherein to determine that the failure of the temperature sensor of the HVAC system has occurred, the processor is configured to determine that the HVAC system does not have a local outdoor temperature sensor installed.
