Power supply and control panel

Function and use

- Control of all processes and devices in the air handling unit, and particularly the execution of control functions (temperature, airflow, CO2, relative humidity) and protection functions (energy heat exchanger protection against condensate freezing, water heater protection against heating medium freezing, fan motor overload protection etc.)
- Autodiagnostics, maintenance of alarms.
- Archiving of all operating parameters.
- Joint operation with user interfaces (HMI).
