MODULATING VENTILATION
As with step ventilation, the management logic for
modulating ventilation offers two possible operating modes:
AUTOMATIC operation
fixed-speed OPERATION
The operating percentage is selected by pressing the UP/
DOWN keys, while automatic ventilation comes on when
ventilation is set below the minimum (20%) or above the
maximum (100%) values.
MANUAL ventilation
AUTOMATIC ventilation
FORCED ventilation

HEATING WITH 4-SPEED CONFIGURATIONS

For configurations with 4 speeds, ventilation
for heating is delayed by 0.5°C to allow for an
initial natural convection phase.
WATER CONSENT
Regardless of what type of fan is installed (step or
modulating), ventilation depends on the system's water
temperature control. Depending on the work mode, we will
have different consent thresholds for heating and cooling.

HEATING
o
Failure to have this consent, when the thermostat sends
a signal, will be displayed by the flashing symbol of the
mode that is currently in operation Cooling or Heating. This
enabling signal will be ignored if:
the water probe is not required or it is in alarm conditions
because it is disconnected
Cooling with 4-pipe configurations
FORCED OPERATIONS
Normal ventilation logic (modulating and non-modulating)
will be ignored in particular forcing situations which could be
necessary for the correct temperature control or functioning
of the terminal.
