Proportional Controllers for heating •

circuits

Can be used with RA-N, RA-G and •

RA-C

FEV-IF can be used in ﬂoor, ceiling or •

radiator heating

FEV-FF can be used with fancoil or •

induction units

The FEV is a proportional controller

which opens or closes the heating

valve as a function of the temperature

deviation.

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.

FEV-IF

To be applied in systems with

ceiling, ﬂoor or radiator heating. The

temperature adjuster/sensor should be

mounted on an internal wall at a height

of approximately 1.5 metres in such a

way that the room temperature can be

measured accurately.

FEV-FF

To be applied in systems with 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.
