Abstract
Systems and methods can be used to provide auxiliary switching. An actuator in a heating, ventilating or air conditioning (HVAC) system can include a motor, a drive mechanism driven by the motor and configured to move an HVAC component among positions, a latch relay auxiliary switch, and a controller. The controller is configured to provide a control signal to the latch relay auxiliary switch to open and close contacts of the latch relay auxiliary switch and operate the motor to move the HVAC component based on a determined position.
Claims20
An actuator in a heating, ventilating or air conditioning (HVAC) system, the actuator comprising:
- a motor;
- a drive mechanism driven by the motor and configured to move an HVAC component among positions;
- a latch relay auxiliary switch;
- and
- a controller configured to:
- provide a control signal to the latch relay auxiliary switch to open and close contacts of the latch relay auxiliary switch;
- and
- operate the motor to move the HVAC component based on a determined position.
An actuator system, comprising:
- a drive mechanism configured to move an HVAC component;
- a latch relay auxiliary switch;
- and
- a controller configured to provide a relay control signal to the latch relay auxiliary switch to open and close contacts of the latch relay auxiliary switch and an drive control signal move the HVAC component based on a determined position of the drive mechanism.
A method of controlling a heating, ventilating or air conditioning (HVAC) actuator that includes a motor, a gear driven by the motor and coupled to a movable HVAC component, and an auxiliary switch, the method comprising:
- operating the motor to change a position of the movable HVAC component in response a determined position of the gear or the motor using an electronic actuator control signal;
- and
- operating the auxiliary switch in response the determined position using an electronic switch control signal, the auxiliary switch being a latch relay switch.
