Stock no. BPZ:RVL480

Stock no. BPZ:RVL480

Key functions

Weather-compensated flow temperature control, with or without room influence

6 preprogrammed plant types are provided

Plant system

  • Control of a mixing valve serving a heating zone (space heating)

  • Control of a burner (1- or 2-stage)

  • Control of a valve in the primary return of a heating zone with district heat connection

  • Demand-dependent control (precontrol) of a mixing valve / of the boiler temperature / of a heat exchanger (heat demand signal via data bus)

Additional functions

The RVL480 offers the following functions (no submodules or extra devices required):

  • Display of parameters, actual values, operating states and fault status signals

  • 7-day program with 3 heating periods per day

  • 2 additional programs, each with 3 switching periods per day

  • Automatic summer/winter changeover

  • Holiday program (up to 8 holiday periods per year)

  • Optimum start/stop in accordance with the heating program (with or without room influence)

  • Automatic ECO function, depending on the outside temperature and the type of building construction

  • Optional remote selection of operating modes (via room unit or external switch)

  • Scalable DC 0…10 V output for passing on the heat request to other devices

  • Quick setback and boost heating

  • Preselection of flow temperature setpoint via external contact

  • Minimum and maximum limitation of the flow temperature

  • Minimum and maximum limitation of the return temperature (shifting / constant)

  • Maximum limitation of the room temperature

  • Communication with other devices via the data bus

  • Limitation of the return temperature differential (DRT) for district heat applications

  • Frost protection and pump protection
