Abstract: A controller assembly controls water flow through individual emitters of a heating/cooling system based on a temperature setpoint and room temperature indicator obtained from an associated thermostat. The controller assembly provides delta temperature room control using a high precision movement actuator fitted with two pipe temperature sensors to power modulate individual radiators, underfloor heating circuits or fan-coils to provide energy efficiency for individual room heating/cooling control.

As the room temperature approaches the setpoint so that the temperature difference decreases, the power output of the emitter is modulated to achieve desirable performance characteristics.
