P6865HG-R (Modulating): This model is designed for 3-speed fan and modulating valves (0-10V or similar) in fan coil systems. Allows remote sensor function. Replaces T6865H2WG-R

P6865HG-M (Motorized/On-Off): Typically denotes suitability for motorized, on/off valve control rather than proportional modulating control. Built-in sensor. Replaces T6865H2WG-M

Choose the P6865HG-M if you have a standard on/off valve actuator.
