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 [K]
Control type = 1, 2 or 3 speeds
0,3 K
[other values in the range 0,2 K
…3 K]
Proportional band [0,1 K]
Control type = continuous
regulation
30
[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.
Min. change of value to send [%]
Control type = continuous

10
[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
For carrying out the function must be enabled a sensor for measuring
the temperature of the heat exchanger of the fan coil. 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
For carrying 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]
