Systems and methods for operating an hvac system

A control system for a heating, ventilation, and air conditioning (HVAC) system, wherein the control system comprises:

• a sensor configured to detect an operating parameter of the HVAC system;
• processing circuitry;
• and
• a memory comprising instructions that, when executed by the processing circuitry, cause the processing circuitry to:
• receive data indicative of a value of the operating parameter from the sensor;
• compare the value of the operating parameter to a threshold value of the operating parameter, wherein the threshold value is different from a limit value of the operating parameter that causes a switch of the HVAC system to actuate and interrupt operation of the HVAC system;
• and
• adjust operation of the HVAC system in response to a determination that the value of the operating parameter exceeds the threshold value.

A heating, ventilation, and air conditioning (HVAC) system, comprising:

• a heat exchanger configured to receive a working fluid and place the working fluid in a heat exchange relationship with an air flow directed across the heat exchanger;
• a fan configured to direct the air flow across the heat exchanger;
• a switch configured to detect an operating parameter of the HVAC system, wherein the switch is configured to interrupt operation of the HVAC system in response to detection of a first value of the operating parameter greater than an operating parameter limit value;
• and
• a controller configured to:
• receive data from a sensor indicative of a second value of the operating parameter;
• compare the second value of the operating parameter to a threshold value of the operating parameter, wherein the threshold value is less than the operating parameter limit value;
• and
• adjust operation of the fan in response to a determination that the second value of the operating parameter is greater than the threshold value.
