RVL481

Контроллер теплоснабжения

Key functions
Weather-compensated flow temperature control, with or without room influence, with simultaneous demand-compensated boiler and DHW control.
29 preprogrammed plant types can be selected from a combination of 6 heating applications and 5 DHW applications.

Heating circuit plant types

• Control of a mixing valve serving a heating circuit (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)

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
• Charging of DHW storage tank through control of a diverting valve
• DHW heating via heat exchanger through control of a 2-port valve in the primary return
• DHW heating with electric immersion heater only
• DHW heating with solar collector

Additional functions
In addition to the functions of the RVL480, the RVL481 offers the following functions (no submodules or extra devices required):

• 2 programs for heating and DHW, each with 3 heating periods per day
• 1 multifunctional relay for switching on/off the plant according to various parameters and functions
