HMI controller

HMI is a method for controlling 3-speed fans that ensures lower investment costs and easier installation. It also offers greater aesthetics, as instead of two components: a controller and a speed regulator, only one HMI controller is required. Enhanced functionality allows for adjusting operating parameters to individual needs, and the combination of automatic regulation with a weekly programmer creates an autonomous control system.

  • HMI controller is compatible with LEO  units,
  • automatic or manual 3-step fan speed regulation,
  • temperature control in the room (due to opening/closing of the valve or automatic setting of fan speed),
  • possibility to control max. 18 units via single HMI controller (use of 3 RX splitters is essential),
  • fan operation in continuous or thermostatic mode,
  • operating modes: heating, cooling, ventilation, 
  • antifreeze - protection against too low temperature in the room,
  • possibility to connect external temperature sensor NTC,
  • possibility of connection to BMS.
