THERMOSTATS
FHV-R provides temperature control of under oor heating circuits, using a return temperature limiting valve tted with a type FJVR sensor
element. FHV-R is used in applications where a desired oor temperature is required (e.g. a bathroom where a constant warm oor is preferred
regardless of room temperature to ensure comfort and to quickly dry water on the oor). Set includes wall enclosure box, front cover, bleed
key and valve (return temperature limiter) with air vent. An FJVR sensor is required for controlling the return temperature. Also required are two
union nuts and tailpieces per control. When the FHV-R is used for controlling oor heating, the heated oor area should not be more than 100
sq.ft. (10 m2).

FHV-A enables room temperature control via a pre-settable thermostatic valve tted with a type RA 2000 sensor element. Set includes wall
enclosure box, front cover, bleed key and pre-settable valve with air vent. A type RA 2000 sensor element is required for controlling the room
temperature. Also required are two union nuts and tailpieces per control. NOTE: If using the FHV-A for room temperature control, the ow
temperature should not be permitted to exceed the maximum recommended by the ooring manufacturer.
