COMPACT Control System
General
Temperatures, airflows and components are continuously
supervised. If abnormal conditions or possible malfunc-
tions arise, an alarm is initiated.
Alarms are indicated by an alarm text and flashing LED on
the control panel/hand-held micro terminal.
Complete description of alarms and setting options are
specified in the Operating and Maintenance Instructions
for the COMPACT (see www.swegon.com). A general de-
scription is given below:
Alarm Limits
Alarm limits can be preset for the following:
• Nonconforming supply air temperature.
• Min. extract air temperature.
• Filters.
• Heat exchanger.
• Service period.
Fire Alarms
External fire alarm
Used for external fire-control equipment.
Internal fire alarm
The air handling unit’s internal temperature sensors serve
as fire protection thermostats. An alarm is initiated if the
supply air temperature sensor registers more than 70 °C
or when the extract air temperature sensor registers more
than 50 °C.
Fans, in the event of a fire
The fans in the air handling unit can be controlled to op-
erate in the desired speed mode for evacuating combus-
tion gases in the event of a fire alarm.
External Alarms
External alarms 1 and 2
The external alarms can be used for external functions
such as motor protection for circulation pump and service
alarm for smoke detectors.
Alarm Priority
In the case of all the alarms, you can assign priority A or
B and chose whether or not the red alarm LED on the
control panel/hand-held micro terminal shall light up in
the event of an alarm. For certain alarms it is also possi-
ble to choose whether or not the air handling unit will be
switched off if this alarm is initiated.
Alarm Blocking
Certain alarms can be activated or blocked, for example
temperature and flow alarms.
