FEV-IF with integrated sensor |
FEV-FF with remote sensor |
The FEV is a proportional controller which opens or closes the heating valve as a function of the temperature deviation.
FEV-IF
To be applied in systems with i.e. ceiling-, flooror radiator heating. The temperatureadjuster/sensor should be mounted on an internal wall at a height of approximately 1.5 meter in such a way that the room temperature can be measured accurately.
FEV-FF
To be applied in systems with i.e. fancoils or induction units. By placing the remote sensor in the room-air inlet of the unit a smaller response time to temperature changes can be achieved which will result in a more accurate temperature control.

FEV sensors can be applied in combination with RA-N RA-G or RA-C valves. The FEV sensors are equipped with a direct acting valve-controller that opens the valve when the
temperature drops below the set temperature. If the set temperature is equal to or higher than the room temperature the valve is closed.
Temperature setting
Comfort temperature ~ 22°C at Xp = 0 K(°C)
The FEV sensors have been developed for heating via water-based systems.
The FEV sensors are based on the self-acting principle. The liquid-filled sensors control the valves via capillaries and adapters.
The scale shows the approximate set-point offset from the comfort temperature which is approximately 22° C at Xp = 0 K.
