siemens RVL482 - Контроллер отопления SIGMAGYR с коммуникацией

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
