6.1.1 OFF state for alarm
When the machine is active and an heavy alarm occurs the unit switches into the OFF due to alarm
status. In this case the unit and all devices are switched OFF and the dampers are completely closed
until the alarm condition has been reset. When the unit is OFF for alarm it is possible to switch to
the other OFF states by means of the relevant digital input, key or supervisor.
The alarms that cause the “OFF for alarm” are:
- Supply fan thermal overload alarm
- Return fan thermal overload alarm
- Differential pressure switch alarm
- Outdoor air Damper limit switch alarm
The unit recovers the normal working mode when the alarm has been reset.
6.2 RTC setting
When the board is disconnected from the mains for many days the RTC (Real Time Clock) system
clock backup battery discharges. At the next connection to the mains the controller will display an
RTC alarm. To get rid of it and allow a proper working condition the RTC has to be updated using
the below mask:
Once the clock is configured, press OK to update the RTC and access the main page of the
application. Confirmation by pressing OK also resets any clock alarm (AL16) as long as the alarm
conditions are reset.
If the alarm should not disappear switch OFF and back ON power supply to the board and manually
reset the alarm.
6.3 Restore the (factory) default parameters
Via the “Parameters Reset” procedure it is possible to bring back the system parameters to the
default value. The procedure can only be activated with machine in OFF mode
Enter the Installer ->Various Parameters -> Default menu and press the ENTER key.
