RVL482 - Heating controller for boiler temperature control for modulating or 2-stage burners with d.h.w. heating
RVL482
Heating controller for boiler temperature control for modulating or 2-stage burners with d.h.w. heating
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
