Using the supervision protocol
This procedure can only be used if the serial card is present.
Check in the "User menu" that the parameters "Serial line enabling" and "On/Off enabling from supervisor" are set to "Yes".
Proceed as follows:
•
To switch on: send the switching on command from the protocol. The corresponding icon is displayed in the main mask.
Note: the unit does not switch on if it is set to "Off from keyboard" or "Off from digital input".
•
To switch off: send the switching off command from the protocol. The corresponding icon is displayed in the main mask.
3.4 START OF AUTOMATIC ADJUSTMENT
Temperature and humidity adjustment is enabled 60 seconds (settable time, minimum value: 20 seconds) after the unit is
activated, that is, after ventilation is started. The aim is to give the unit time to circulate the ambient air for long enough to assure
correct reading of ambient temperature and humidity values.
Automatic adjustment permission is immediately withdrawn when ventilation is disabled or when the manual commands are
enabled.
3.5 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 in the manual mode is the management
of the alarms protecting the safety and integrity of the devices. The 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 "Safety" menu up to a maximum of 60 min). 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.
