FED Sequential Controller
Brand: Danfoss
The FED sensors are used in applications in which a cooling and a heating circuit are to be controlled by one controller.
Both FED-IF and FED-FF sensors can be applied to chilled ceilings, fancoils and induction units. For control of cooling and heating circuits in fancoil and induction units use the FED-FF with remote sensor.
By placing the sensor in the air inlet a quicker reaction time of the air temperature changes is achieved. Using the remote sensor, the remote temperature adjuster can be placed directly on the cabinet.
The FED sensors are applied with the RA-N and the RA-C valves.
The FED sensors are equipped with a reverse device for the control of cooling circuits. With the reverse device the valve in the cooling circuit will open when the temperature rises above the setpoint temperature.
The valve in the heating circuit will open when the temperature falls below the set-point temperature.
