The periodic fan kick time can be selected individually for Comfort mode via
parameter P60, and for Economy mode via parameter P61.
 Fan kick value “0” means the fan runs continuously in the dead zone.
 Fan kick value “OFF” means the fan does not run in the dead zone.
The fan kick (P60) and Fan in dead zone (P15) are combined as an OR-function.
SW < 7.2 / device index < E in Comfort mode: the fan function in the dead zone is
enabled / disabled via P60.
When the fan starts from standstill, it starts at speed 3 for 1 second to ensure safe
fan motor start by overcoming inertia and friction (selected via parameter P58).

When the electric heater is switched off, the fan overruns for 60 seconds
(parameter P54) to avoid overtemperature of the electric heater or prevent the
thermal cutout from responding.
In case of fan failure, the thermostat cannot protect the electric heater against
overtemperature. That is why the electric heater must feature a separate safety
device (thermal cutout).
The clean fan filter reminder function counts the fan operating hours and displays
message “FIL”
to remind the user to change /clean the fan filter as soon as the
threshold is reached (can be set via parameter P62). This does not impact the
thermostat's operation, which continues to run normally.
The clean filter reminder is reset when the operating mode is manually set to
Protection and back.
In Auto Timer mode, the default fan mode is automatic. The fan mode can be
changed to manual by pushing the “FAN” button. The fan returns to the automatic
default mode after each switchover from Comfort to Economy mode and vice
versa.
To let the heating / cooling coil reach its temperature, the fan start can be delayed
by a time period set via parameter P67.
