Abstract
An actuator in an HVAC system is provided. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to an HVAC component for driving the HVAC component between multiple positions. The actuator further includes a processing circuit. The processing circuit is coupled to the motor and configured to transmit control signals to operate the motor to drive the HVAC component between a first position and a second position, monitor temperature data received from one or more temperature sensors, determine that the temperature data does not meet an expected performance criterion and transmit an alarm signal.
Claims20
An actuator in an HVAC system configured to modify an environmental condition of a building, the actuator comprising:
- a motor;
- a drive device driven by the motor and coupled to an HVAC component for driving the HVAC component between multiple positions;
- and
- a processing circuit coupled to the motor and configured to:
- transmit control signals to operate the motor to drive the HVAC component between a first position and a second position;
- monitor temperature data received from one or more temperature sensors;
- and
- modify a control logic function of the actuator for at least one of the motor or the drive device in response to the monitored temperature data, wherein modifying the control logic function comprises modulating the actuator using a different control logic function in response to a determination that temperature data is at least one of unexpectedly positive or unexpectedly negative.
A method for operating an actuator in an HVAC system, the method comprising:
- transmitting, by a processing circuit of the actuator, control signals to operate a motor coupled to a drive device configured to drive an HVAC component between a first position and a second position, wherein the actuator, including the motor, drive device, and processing circuit, is configured to be physically coupled to the HVAC component via the drive device;
- monitoring, by the processing circuit, temperature data received from one or more temperature sensors;
- and
- modifying, by the processing circuit, a control logic function of the actuator for at least one of the motor or the drive device in response to the monitored temperature data, wherein modifying the control logic function comprises modulating the actuator using a different control logic function in response to a determination that the temperature data is at least one of unexpectedly positive or unexpectedly negative.
