When a unit is switched off using one of the procedures previously described, the shutdown command will be sent to the PAC-IF cards and ventilation will remain in operation

until the Mr. Slim units are switched off. This transitional period will be notified by the ventilation and the compressor icons flashing at the same time.

In case of s-MEXT unit blocking alarm, ventilation is immediately disabled and the external Mr Slim unit immediately stops.

The blocking alarms are:

•

Air flow differential pressure switch

•

Clogged filter differential pressure switch

•

Heater thermostat

•

Fire/Fumes sensor

•

Flooding sensor

•

Gas leak detected (ventilation forced to maximum level).

MANUAL MANAGEMENT

It is possible to manually start the devices connected to the outputs without using delays, rotating the compressors and regardless of the adjustment and the values

measured by the probes. The only support available in manual mode is the management of the alarms protecting the safety and integrity of the devices. Manual activation of

the analogue outputs allows a value between 0 V and 10 V to be forced. This is expressed on the user terminal as a percentage (between 0% and 100%).

The manual procedure can be activated at any time during unit operation and terminates if it is manually disabled by the user or if a maximum time of 30min has elapsed (this

time can be set from the "Factory" menu up to a maximum of 60min). There is always a flashing signal on the display.

The parameters for activating and managing the manual mode are in the "Manual" menu, which can be accessed by entering the "Service" password.
