Siemens RVL482 As RVL481 + Boiler SequencingSiemens RVL482 As RVL481 + Bolier Sequencing· The RVL482 is a multifunctional heating controller for use in residential and nonresidential buildings that have their own d.h.w. heating facility · Suited for:- Heating zone control with or without room influence via weather-compensated flow temperature control and, simultaneously, demand-compensated boiler temperature control - Precontrol via demand-compensated boiler temperature control. Suited for int egration into heat source cascades or heat generation systems (heat pump, solar, wood-fired boiler)· For use in heating plants with own heat generation or in interconnected systems· With regard to d.h.w. heating, the RVL482 is suited for plants with d.h.w. storage tanks, electric immersion heaters, solar d.h.w. heating and instantaneous systems with own heat exchangers· The RVL482 has 21 plant types pre-programmed. When a certain type of plant is selected, all functions and settings required for that particular plant will be activated· A multifunctional relay provides additional control functions, if required· 2 separately scalable voltage inputs DC 0…10 V are used to receive heat demand signals from external consumers· The RVL482 has connection facilities for one wind sensor and one solar sensor· For the direct setting of the heating curve, the “little bar" is used. The heating curve can also be set in digital form. A setting knob is used for making room temperature readjustments· All the other parameters are set digitally based on the operating line principle· The RVL482 is capable of communicating with other units via LPB (Local Process Bus)· Key design features: Operating voltage AC 230 V, CE conformity, overall dimensions to IEC 61554 (144 x 144 mm)
