Heating

HMG 4 4-Channel Heating Actuator (Basic Module)

The MIX series is a range of devices comprising of basic modules (e.g. HMG 4) and upgrade modules (e.g. HME 4).
Up to 2 extension modules can be connected in series to the base modules in this series.

The heating actuators control thermal positioning actuators based on the control variable of the room temperature controller, and make it possible to integrate a boiler control. It is also possible to control a circulation pump directly via the actuator.

  • Silent semiconductor switch
  • 4 floating outputs 24–250 V AC
  • Up to 5 positioning actuators per channel
  • 4 LEDs for the status display
  • 4 ON/OFF/BUS rotary switches
  • Continuous or switching control variable selectable
  • Compulsory object for each channel
  • Emergency program in case of bus and message failure
  • Summer operation (prevents unwanted heating in summer) and valve protection
  • Pump control directly by the actuator
  • Minimum and maximum control variables are adjustable, generating various responses to falling below or exceeding the control variables (individually selectable)
  • Determining the maximum control variables for all channels to integrate the boiler control
