HvacFloatingActuator is an Arduino library that can be included in a program to control a floating actuator.
Floating actuators are used extensively in the HVAC controls industry to control valves and dampers. This style of actuator uses two digital outputs to control a 24 VAC signal which tells the actuator to drive open or closed.
This library takes a 0 - 100% input and calculates how long to pulse each output based on variables provided when the instance is created. The library will also reset the actuator position at a definable frequency. This compensates for the minimal drift that occurs after operating over time.
