Main and auxiliary ventilation
The
Ventilation
folder includes the following parameters:
Control type
Threshold first speed [0,1 K]
Threshold second speed [0,1 K]
Threshold third speed [0,1 K]
Speed control hysteresis [K]
Proportional band [0,1 K]
Minimo cambiamento valore da inviare [%]
Manual operation
Hot start
Min. temp.to start ventilation [°C]
Antistratification function
Antistratification temp. differential
Hysteresis
Disable ventilation from bus
Signal from bus
Fan start delay
Fan stop delay
The conditions for the appearance of the
Ventilation
folder are:
Heating
Type of heating = fan-coils or Type of cooling = fan-coils
or a combination of the two conditions:
Heating
Type of heating = floor radiant panels or ceiling radiant panels and
Heating
Ventilation
Auxiliary heating = enabled
Cooling
Type of cooling = floor radiant panels or ceiling radiant panels and
Cooling
Ventilation for
auxiliary = enabled
This way two types of installations can be controlled: i) fan-coil terminals or ii) radiant panels as main stage
and fan-coil terminals as auxiliary stage.

Conditions
Values
Control type
1 speed
2 speeds
3 speeds
continuous regulation
Threshold first speed [0,1 K]
10
[range 0
… 255]
The value is represented in tenths of Kelvin degrees. If the
parameter Thermostat function = both heating and cooling, the
threshold value is valid for both seasonal modes.
Threshold second speed [0,1 K]
Control type = 2 speeds
20
[range
0 … 255]
The value is represented in tenths of Kelvin degrees. If the
parameter Thermostat function = both heating and cooling, the
threshold value is valid for both seasonal modes. For a correct
operation of the ventilation, Threshold second speed > Threshold
first speed.
