5. SMOKE DETECTOR
The smoke detector is an option.
When smoke is detected in the room air, the exhaust blower and the Economizer (external damper) are
managed separately via the Service menu. The unit goes into override shutdown, the main and return fan
are stopped but the economizer can be configured open or closed depending on the legislation applicable
in the country of installation.
6. SCHEDULING
This feature is only available if the board has a clock card fitted.
Two kinds of scheduling are available, via the Clock menu:
²
Weekly scheduling
²
Daily scheduling
6.1. WEEKLY SCHEDULING
Weekly scheduling controls the unit’s switching ON and OFF during the week, determining either the ON or
OFF state for each single day.
Weekly scheduling can be enabled via the Clock menu.
For each day of the week, a parameter is set that controls the unit’s switching ON and OFF.
Each day at midnight, the controller will check whether the variable related to that day is set to ON or OFF
and will switch the unit ON or OFF accordingly.
Example:
²
Weekly scheduling enabled
²
Unit running on Monday = ON
²
Unit running on Tuesday = ON
²
Unit running on Wednesday = ON
²
Unit running on Thursday = ON
²
Unit running on Friday = OFF
²
Unit running on Saturday = OFF
²
Unit running on Sunday = OFF
With this setup, the unit will be ON from 00:00 on Monday until 23:59 Thursday evening; it will stay OFF
from 00:00 on Friday until 23:59 Sunday evening.
It is also possible to parameter a specific operation for the main fan when the unit is OFF by scheduling. For
example, at night (daily scheduling ON/OFF, outside the band) or the days that are programmed OFF, it can
be interesting to let the main fan ON, to have a continuous air circulation in the building. This parameter is
available in the Clock menu.
