Fan control
*093
Auto Fan speeds are changed over automatically
(by the room controller). Manual fan speed presetting is possible only
in operating mode Comfort.

Manual All fan stages can only be set manually (on the room unit via PPS2).
Exception: The fan changes to automatic operation when the room
temperature is outside the Protection setpoints.
0
Enable fan relay
*173
Enabled The relay (Q34) is activated when the fan speed demand (YC3)
exceeds 4% and it is deactivated when the demand is 0%
(hysteresis).
See the data sheet for relay data.
1
Disabled The relay is always deactivated.
Connect the fan supply directly to the fan.

9.5 Minimum on time
Each fan speed remains on for a pre-defined minimum period before switching to the
next higher speed. This enables the controller to adjust to the fan speed
9.6 Fan overrun time (switch-off delay)
When switching off an electric reheater (FNC03, FNC05), it is essential to ensure that
the residual heat from the electric heater battery is dissipated.
For this reason, the fan is switched off only after a delay. The overrun time and the
appropriate fan speed (no less than 10%) can be defined.
