Special features

  • Heating and district heating controller
  • The TROVIS 5573-1 Heating and District Heating Controller is used to control max. two control circuits:
    • Control of a primary heat exchanger or boiler
    • Max. one mixing and one non-mixing heating circuit (both outdoor temperature controlled) as well as control of DHW heating in the secondary circuit
    • Outdoor-temperature-controlled buffer storage tank control with solid fuel boiler and solar circuit control
    • Control of one outdoor-temperature-controlled heating circuit and a DHW heating with two valves in the primary circuit
    • Control of two outdoor-temperature-controlled heating circuits with two valves in the primary circuit
    • Optionally with icons on the display or plain text on the graphics display
    • Direct access to the operating modes and essential parameters of the individual control circuits using a rotary pushbutton
    • Enter and retrieve data intuitively by turning and pressing the button
    • 365-day clock with max. four time schedules and automatic summer time/winter time changeover
    • Max. three times-of-use per day (entered in steps of 15 minutes)
    • Room panels can be connected for the individual heating circuits
    • Demand-driven control by set point demand by subsequent controllers using an 0 to 10 V signal
    • Applications including solar thermal DHW available
    • Heating characteristic optionally based on gradient or four points
    • Flexible limitation of the return flow temperature
    • Adaptation: automatic adaptation of the heating characteristic (room temperature sensor required)
    • Optimization: calculation of the best possible activation and deactivation times for heating (room temperature sensor required)
