FHV-A / FHV-R thermostats

FHV-R provides temperature control of under floor heating circuits, using a return temperature limiting valve fitted with a FJVR sensor element.

FHV-R is used in applications where a desired floor temperature is required (e.g. a bathroom where a constant warm floor is preferred regardless of room temperature to ensure comfort & to quickly dry water on the floor).

Set includes wall enclosure box, front cover, bleed key and valve (return temperature limiter) with air vent. When the FHV-R is used for controlling floor heating, the heated floor area should not be more than 100 sq.ft. (10 m2).

FHV-A enables room temperature control via a pre-settable thermostatic valve fitted with a RA2000 sensor element.

Set includes wall enclosure box, front cover, bleed key and pre-settable valve with air vent.

If using the FHV-A for room temperature control, the flow temperature should not be permitted to exceed the maximum recommended by the flooring manufacturer.
