RVL482

Heating controller for boiler temperature control for modulating or 2-stage burners with d.h.w. heating

Stock no. BPZ:RVL482

Stock no. BPZ:RVL482

Key functions

Weather-compensated flow temperature control, with or without room influence, with simultaneous demand-compensated boiler and DHW control.

21 preprogrammed plant types can be selected from a combination of 5 heating applications and 4 DHW applications.

Heating circuit plant types

  • Control of space heating through control of a mixing valve in the heating circuit

  • Control of space heating through control of a mixing valve with simultaneous demand-dependent control of the boiler temperature

  • Control of space heating through control of mixing valve and boiler, plus minimum limitation of the boiler return temperature with own mixing valve

  • Demand-dependent control (precontrol) of the boiler temperature (heat demand signal via bus)

  • Demand-dependent control (precontrol) of the boiler temperature with minimum limitation of the boiler return temperature via mixing valve (heat demand signal via bus)

DHW plant types

  • Charging of DHW storage tank through control of a charging pump.

  • Charging of DHW storage tank through control of a mixing valve

  • DHW heating via heat exchanger through control of a 2-port valve in the primary return

  • DHW heating through electric immersion heater only

  • DHW heating with solar collector

Additional functions

In addition to the functions of the RVL480 and RVL481, the RVL482 offers the following functions:

  • 2 scalable DC 0…10 V inputs for heat demand signals from external consumers

  • Connection facility for solar and wind sensor (refer to chapter "Sensors")

  • Control of a boiler or circulating pump

  • Optional selection of circulating pump/bypass pump

  • Three 7-day programs, each with 3 heating periods per day
