Siemens RVL469 Brand Introduction Siemens RVL469 is heating circuit controller developed by Siemens Building Technologies for building HVAC heating zone regulation. It specializes in weather-compensated flow temperature control for secondary heating circuit, working together with partner controller for mixing valve three-position control. Heating Controller is the core unit of Siemens RVL469. Heating Controller adopts wall-mounted compact casing design. Heating Controller supports multi temperature sensor input including outdoor, flow and room sensor. Heating Controller realizes automatic heating curve adjustment and mixing valve regulation. Siemens RVL469 provides stable Regulation for workshop and building heating system. Regulation has built-in weekly timer and holiday program. Regulation supports frost protection and ECO energy saving function. Regulation allows adjustable flow temperature limit and heating curve parameter. Siemens RVL469 features reliable Bus for heating system network connection. Bus adopts LPB local process bus communication. Bus is compatible with Siemens RVL470 series main controller. Bus supports data exchange between paired heating controllers and room operating units. Siemens RVL469 is widely used in residential buildings, commercial premises and legacy heating control system renovation. With mature Siemens HVAC control technology, this heating controller works with AC230V power supply and has stable long-term operation performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted secondary heating zone controller solution.
