Control system H 3200 Touch

Microprocessor controls for optimising the combustion process through precise control of the boiler- and exhaust gas temperature, including actuators for primary and secondary air dampers, 7 ” color display for the representation of all important values and status messages with USB interface for updates; including lambda control

Scope of delivery:

Core module

    • 2 mixing heating circuits (outside sensor included) and
    • 1 speed-controlled pump output or change-over valve
  • Hydraulic module
    • 2 speed-controlled outputs for pumps or switching valve
    • 6 sensor inputs
  • Outside sensor
  • Contact probe for 1 mixing heating circuit (2nd heating circuit possible via additional sensor)

Optional:

Control expandable to 18 heating circuits (wall enclosures) and total 8 hydraulic modules (wall housing); thereby numerous additional functions such as solar, oil / gas boilers, circulation, differential control (e.g., water-borne chimney insert), etc. are possible. For additional equipment see connection diagrams
