In case of motor overheat fan stops automatically and sends an overheat information to MSR220VA (KB1) module. To start
the heater user has to reset the module (additionally temperature of the fan needs to cool down). Fan motor has additional
overcurrent protection. Auxiliary protection is ensured by phase asymmetry, sequence, failure detection.
