SURVEILLANCE MODE
To get into this mode, repeatedly press the button MODE (M) to see the image
SURVEILANCE on display. When pressing MODE button the mode will change in the sequence
(AUTO, SURVEILLANCE, MANUAL, AUTO, SURVEILLANCE…)
In this mode the HUMIDITY button (H) is active to select the desired threshold. In this mode both
humidity and twilight sensors are active, the units will normally be in stand-by with front panel closed,
this means that when the humidity level exceeds the set threshold the units start running in extraction.
Hereinafter explaining how the units run in different situations with related operating mode:
•
In standard humidity conditions the units are in stand-by with the front panel closed and the
sensors active.
•
In case of humidity alarm conditions during the day the units run in extraction at the medium
speed.
•
In case of humidity alarm conditions during the night the units run in extraction at the minimum
speed.
The units get into humidity alarm when the MASTER unit detects a humidity level higher than the set
threshold among the three values available (40%, 60%, 90%).
Recommendation:
Recommended mode when heat recovery is not needed but essential to have ventilation because of
humidity (or CO2). Typical use in holiday homes since heat recovery may not be needed and a proper
ventilation is essential to prevent air stagnation in the premises.
MANUAL MODE
To get into this mode, repeatedly press the button MODE (M) to see the image MANUAL on display.
When pressing MODE button the mode will change in the sequence
(AUTO, SURVEILLANCE, MANUAL, AUTO, SURVEILLANCE…)
In this mode the IMPELLER button (V) is active to select the desired speed. In this mode the sensors
are disabled, and the units will run with heat recovery. The user can select the desired speed to run the
units and this condition remains until a different command is entered.
Recommendation:
Recommended mode when heat recovery and ventilation is required independently from humidity
levels or when needed to set a fixed speed for all units.
