Light emitting diode (LED)
Corrigo L10 has an LED to indicate one or more
alarms in the alarm queue. When not lit it means there
are no alarms in the alarm queue. If it flashes, new
unconfirmed alarms are pending. If it is constantly lit it
means that there are confirmed but non-reset alarms in
the queue.
16. Setpoint frost protection
17. Setpoint shutdown mode
18. Pump stop temperature and delay
19. Extended run time with pushbutton on DI3
20. Cool-down time (when using electric heater)
21. DX minimum On/Off times
22. Lowered min limit on DX-cooling
23. Outdoor temp. for blocking DX-cooling
24. Show min/max for analogue inputs (Yes/no)
25. Damping of AI1...AI4
26. Parameters for deviation alarm (max diff. and delay).
27. Outdoor temperature span
28. Alarm delay - fans
29. Alarm output blocking
The alarm output can be blocked so that some
pending alarms only activate the alarm output
during certain times. In the blocked state all alarms
are blocked except frost alarm, over-temperature
alarm and smoke alarm that will always trigger the
alarm output. Although an alarm has been blocked it
will be registered and indicated by the alarm
indicator on the front panel. Texts in the alarm
queue will appear as normal.

Storage of parameters and settings
All settings and paramters are stored in non-volatile
memory. this means that C
ORRIGO
L10 does not have to
be reprogrammed even when subjected to very long
periods of power loss.
The real time clock in C
ORRIGO
L10 has a powerfail
backup that lasts for about 24 hours. If subjected to
longer periods of power loss, the clock has to be set
again but the run periods in the scheduler are not
affected. Any alarms in the alarm queue will be lost
pending power failure.
