PLUG AND PLAY UNIVERSAL INPUT ACTUATOR
First Claim
1. An actuator in a HVAC system, the actuator comprising:
- a motor;
a drive device driven by the motor and coupled to a movable HVAC component for driving the movable HVAC component between multiple positions;
an input connection configured to receive an input signal; and
a processing circuit coupled to the motor and configured to;
determine whether the input signal is an AC voltage signal or a DC voltage signal;
operate the motor using an AC motor control technique in response to determining that the input signal is the AC voltage signal; and
operate the motor using a DC motor control technique in response to determining that the input signal is the DC voltage signal.

Abstract
An actuator in a HVAC system includes a motor and a drive device driven by the motor. The drive device is coupled to a movable HVAC component for driving the movable HVAC component between multiple positions. The actuator includes an input connection configured to receive an input signal and a processing circuit coupled to the motor. The processing circuit is configured to determine whether the input signal is an AC voltage signal or a DC voltage signal. The processing circuit is configured to operate the motor using an AC motor control technique in response to determining that the input signal is an AC voltage signal and configured to operate the motor using a DC motor control technique in response to determining that the input signal is a DC voltage signal.
