Night cooling
The aim of this function is to use the coolness of fresh air from outdoors during the night within the building, with an option of over-
ventilation, as far as the system will allow.
This function is only available if there is a mixing box or a plate heat exchanger equipped with a bypass damper.
It is activated by a timer or the CMS, whilst the room air or return air temperature is checked against a setpoint.
1.6.14
The fault relays
1 relay per fault summary level is provided:
-
"Maintenance" fault summary
-
"Danger" fault summary
"Maintenance" faults are alarms which only send information to notify the operator. They can be validated by pressing the key
for 3 seconds if they have disappeared.
The "Danger" faults, which are of a higher level, are alarms which send information to notify the operator, but also start a process
to secure the unit. They can be validated by pressing the key for 3 seconds if they have disappeared, and after the unit has
been switched off .
It is possible to select the type for each fault (Danger or Maintenance), apart from for the Fire fault.
It is also possible to select the direction of action for the summary relays.
