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.

AUTOMATIC OPERATION FOR 3- OR 4-SPEED UNITS AND 
ON/OFF VALVE/S OR NOT INSTALLED:
COOLING

HEATING WITH 3-SPEED CONFIGURATIONS

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.

COOLING

HEATING

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
