HM 12 T KNX

Description

  • 12-way heating actuator FIX2
  • With 12 temperature controllers (P/PI) for heating and cooling
  • For controlling 12 thermal actuators 24 V - 240 V AC in 4 groups with 3 outputs and 450 mA each
  • (Due to the switch-on behaviour of the actuators, we recommend not to exceed a maximum load of 3x1 actuators 24 V AC or 3x5 actuators 230 V AC)
  • Short-circuit-proof and overcharge protected
  • Continuous or switching actuating value selectable
  • Valve protection function can be deactivated
  • With the modes: comfort, standby, night as well as frost/heating protection
  • Changeover to summer mode possible
  • LED switching status display for each channel
  • Manual operation on device (even without bus connection)
