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.
