The FEV-Z climate sensor is a proportional controller which opens or closes an AB-QM automatic flow limiter valve as a function of the temperature deviation.
The FEV-Z is to be applied in climate systems with i.e. ceiling-, floor- or radiator heating.
The FEV-Z climate 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.
The FEV-Z sensor is 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 open.
FEV-Z has a valve adapter especially designed for use with Danfoss AB-QM automatic flow limiters.
