PARAMETER
DESCRIPTION
VALUES
output. Only the corresponding output of the
assigned fan speed is switched on with this
parameterisation. The outputs are not activated
at the same time.
Hierarchically: The fan speed 1 is controlled with
the corresponding output but the fan speed 2 and
3 are the result of the sum of a new output and
the previous outputs. The individual fan speeds
are activated consecutively (outputs switched on)
until the required fan speed is achieved.
Hierarchically
Switching Wait (x100ms)
2
This parameter set a delay between the switching
of the fan speeds. When the value 0 is configured
the relay of the current speed is opened at the
same time that the next output speed is closed.
15
(0…255)
Heating Valve Lower Limit
(%1…100)
This parameter set the low threshold value for the
fan heating valve.
5
(0…100)
Fan 1 Low
er Limit (%1…100)
This parameter set the low threshold value for the
fan 1.
5
(1…100)
Fan 2 Lower Limit (%1…100)
This parameter set the low threshold value for the
fan 2.
30
(1…100)
Fan 3 Lower Limit (%1…100)
This parameter set the low threshold value for the
fan 3.
70
(1…100)
Hysteresis
for
Fan
Limit
(%0…20)
This parameter determines the hysteresis for fan
limits. This value is proportional to the limits
configured previously.
3
(0…20)
Fan Time Delay for Heating
(second)
This parameter set a delay between the opening
of the heating valve and the fan switching on.
Note that when this time is elapsed the switch
wait time for fan speed has to be elapsed too
before switching on the fan.
15
(0…255)
Fan Time Delay for Cooling
(second)
This parameter set a delay between the fan
switching off and the closing of the heating valve.
15
(0…255)
Manual Fan Control
This parameter allows enabling the manual
control of the fan speed.
Disabled
Enabled
1
This parameter is only visible when the paramete
r “Fan Coil Function” is set to “Change-Over Object”.
2
This parameter is only visible when the parameter “Fan Control Behaviour” is set to “Only One Fan Output
at the Same Time”.
