Danfoss Randall FHV-R Return Temperature Controller

  • FHV control valves are ideally suited to the temperature control of individual under-floor heated rooms and for systems using floor-heating in conjunction with radiators.
  • FHV-R. Set includes wall enclosure box, cover and valve (return temperature limiter). An FJVR sensor element is required for controlling the return temperature.
  • FHV-R Data Sheet

     

     

    Please note: Sensors are sold separatley

    Single Room Extension with Self-Acting Control

    A return temperature limiter will maintain the return temperature from the UFH at a constant level and secure a constant floor temperature. Since there is a co-relation between the floor surface temperature and the room temperature, the room temperature will be held, more or less, at a constant level.

    - Used in systems which are predominately heated by radiators (normal system design temperatures 82/71°C) and where Underfloor Heating represents only a minor part of the system, for example a single room or small extension

    - Used in systems where a mixing valve arrangement, used to reduce the flow temperature of water flowing to the underfloor heating (UHF) circuit to a level acceptable for floor heating, is to be avoided because of cost

    - Used for UFH systems where it is essential to maintain a constant and comfortable floor surface temperature, for example in bathrooms with ceramic tiled floors

    - Also ideal for rooms with high peak of free heat gains, for example conservatories, where a room temperature based control system could result in a cold floor
    Suitable for both central conventional and manifold or distribution pipe-work systems

    - Ideal where easy installation and operation and long life reliability are essential

    - It is only suitable for solid floor constructions and UFH systems where pipes are laid in a counter flow pattern to achieve even floor temperature.

    Danfoss produce a range of self-acting controls which are simple to install. The product, which comprises a valve enclosure which is built into a wall or partition, a valve, a facia plate and a sensor, is available in a version which controls return water temperature, type FHV-R, and a version which controls room temperature, type FHV-A. A description of the application areas for both types follows.

    FHV-R Return Temperature Controller -
    The FHV-R valve utilises an FJVR return temperature limiter sensor which controls the temperature of the water leaving the floor heating circuit. As there is a good correlation between water and floor temperature, the FHV-R solution also ensures a warm floor is maintained. The FHV-R solution is ideal for use in systems operating at normal flow and return temperatures (70-80°C) and provides the perfect solution for areas with high heat gains such as conservatories. A mixing valve is not needed with this type of control.

    FHV-A Room Temperature Controller -
    The FHV-A utilises an RA2000 thermostatic sensor to control room temperature. The FHV-A solution should be used in systems where the flow temperature is below 50°C.

Question

Hi - I've just installed underfloor heating in my new conservatory and I don't want to go to the expense of fitting a manifold so would like to install one of the Danfoss Randall FHV-R Termperature Controls which I understand has to be installed in conjunction with a sensor.  However on your product page you list 2 - can you please advise me which one I would need before I order it from you.

Question

Hello  –  I'm interested in purchasing a danfoss Randall fhv r valve. I've contacted danfoss and got the part list I need. The parts I need are: Fhv r valve 003L100000 and  Sensor.

Answer

Thank you for your enquiry - Please find product page link for the Danfoss FHV-R Valve
http://www.uk-plumbing.com/danfoss-randall-fhv-r-return-temperature-controller-p-1105.html
which are supplied with 3/4" BSP male fittings.
The sensors (choice of two temperature ranges) are purchased separately but normally the
lower temperature sensor is used. Please find page link for the FJVR sensor 10-50c
