7.2 Basic ventilation (continuous and intermittent)
Basic ventilation is the lowest prioritised operating mode. It is interrupted by all
other requests. After an interruption, the basic ventilation restarts. A distinction
is made between continuous and intermittent basic ventilation:
Continuous basic ventilation
With continuous basic ventilation, the fan runs continuously at the set volu-
me-flow (≥15 m³/h).
Intermittent basic ventilation
The volume-flow setting of 7.5 m³/h can only be realised by intermittent opera-
tion of the fan. The fan alternates between active time and pause time, whereby
the basic ventilation mode always starts with the pause time. The fan runs at 15
m³/h during the active time and the fan is off during the pause time.
The control system automatically sets the active and pause times to 30 minutes
each, and these times are not adjustable.
7.3 Manual operation
Manual operation is possible for all variants by activating the switch inputs 1, 2
and 3. The switch inputs are usually switched on or off using a light switch. For
