Corrigo ventilation 3.4 manu

Manual Corrigo Ventilation, revision R Chapter 17 Configuration 97
Recirculation is activated either via a digital input signal or by connecting it to "Timer output 5".
EAF running during
recirculation: No
The extract air fan can be selected to run during recirculation.
17.27 Pretreatment
Control of dampers and pump for preheated or pre-cooled outdoor air via an underground intake
channel. The digital output ”Pretreatment” is set to preheating when the unit is started and the
outdoor temperature is below the set heating start limit (default 8°C) or to precooling when the
outdoor temperature is above the set cooling start limit (default 19°C).
If the outdoor temperature exceeds the set heating start limit by more than 1°C (fixed), preheating
will be aborted, as well as if the outdoor temperature falls below the cooling start limit by 1°C.
If a sensor is configured in the intake duct (”intaketemp”) this temperature will be compared with
the outdoor temperature. If the temperature in the intake duct does not exceed the outdoor
temperature by more than 1°C (adjustable) 5 minutes (fixed) after start-up when using preheating,
preheating will be aborted. The same conditions apply to precooling, i.e. if the intake temperature is
not more than 1°C (adjustable) cooler than the outdoor temperature, precooling will be aborted.
Pretreatment always starts at start-up of the unit, if the outdoor temperature so permits. If
pretreatment is aborted due to a small difference between the intake temperature and the outdoor
temperature, pretreatment will be blocked for 6 hours. Then pretreatment will start (if the outdoor
temperature so permits) and run for at least 5 minutes.

17.28 Alarm setting
Permits configuration of all alarms.
Select the appropriate alarm number (from the alarm list). The alarm text for the alarm will be
displayed and the alarm priority can be set; "A-alarm", "B-alarm", "C-alarm" or "not active". The
extra stop function gives, for each alarm, the option to stop or not stop the unit on alarm activation.
