Parameter name
Conditions
Values
Threshold third speed [0,1 K]
Control type = 3 speeds
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. 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

[range
2 … 40]
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,
Inputs
Input X
[AI] coil
battery temperature sensor
or
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 either an input (configured as analog) or 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
Inputs
Input X = [AI]
antistratification temperature
sensor
or
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 either an
input (configured as analog) or 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).
