Parameter name
Conditions
Values
Threshold third speed [0,1 K]
Control type = 3 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 third speed > Threshold
second speed.
Speed control hysteresis
Control type = 1, 2 or 3 speeds
0,3 K
[other values in the range 0,2 K
…3 K]
Speed proportional band [0,1 K]
Control type = continuous
regulation
30
[range 5 … 100]
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.

[range 2 … 40]
Please refer to the Control Algorithms chapter for further information
about the meaning of this parameter.
Manual operation
not depending on the
temperature
depending on the temperature
If the parameter = not depending on the temperature, the fan speed
set by the user is not changed even when the temperature setpoint
is reached; if the parameter = depending on the temperature, the fan
stops when the temperature setpoint is reached.
Hot start
Thermostat function = both
heating and cooling,
External sensors (from bus)
coil temperature = enabled
no
/ yes
To carry out the function, a sensor for measuring the temperature of
the heat exchanger of the fan coil has to be enabled. To this
purpose, an external sensor (from bus) can be used.
Min. temp.to start ventilation [°C]
Hot start = yes
35
[range 28 …40]
If enabled, the function is active only in heating mode.
Antistratification function
External sensors (from bus)
Antistratification temperature =
enabled
disabled
/ enabled
To carry out the function, at least a sensor for measuring a second
temperature value must be enabled at a different height than that of
the room temperature controller. To this purpose, an external sensor
(from bus) can be used.
Antistratification temp. differential
Antistratification function =
enabled
2 [K/m]
[other values in the range 0,25 …
4,00 K/m]
The DIN 1946 recommends a max temperature gradient of 2 K/m for
rooms with standard height (between 2,70 and 3 m).
Hysteresis
Antistratification function =
enabled
0,5 K
[other values in the range 0,2 … 3
K]
Disable ventilation from bus
no
/ yes
