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
