Main and auxiliary ventilation
The
Ventilation
folder includes the following parameters:
•
Ventilation function
•
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]
•
Minimum change of value to send [%]
•
Hot start
•
Min. temp.to start ventilation [°C]
•
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.

Threshold first speed [0,1 K]
Control type ≥ 1 speed
0
[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
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. For a correct
operation of the ventilation, Threshold second speed > Threshold
first speed.
