AZON-W: Acu-Zone Hot Water Duct Heaters


The AZON-W Acu-Zone hot water duct mounted heaters use a discharge air temperature sensor and PID controller to provide a constant supply air temperature at both design and very low air flows to a single VAV diffuser or to larger zones of VAV diffusers.   When the room temperature drops below the room mode control thermostat set point, the hot water valve is opened. The valve is then modulated by the PID controller to the discharge air temperature sensor to maintain the supply air temperature.
