KNX PARAMETER
SETTINGS
System Type
2 pipes system
4 pipes system
2 pipe system: the hydraulic system is unique and conveys the warm or cold fluid, depending on
the season.
4-pipe system: the hydraulic system has 2 individual circuits, one for heating and one for the
cooling.
Relay state when valve is deactivated
Relay is open when valve is deactivated
Relay is closed when valve is deactivated
Set if the relay must switch ON or OFF in order to Open / Close the valve; the deactivated state
for the valve is when it is closed and the fluid does not pass through.
5.3. Fan Coil Speed Control
The control of 3-speed fan coil can be achieved with 3 communication objects (1 bit) which accept
commands on / off or with a 1-byte communication object for a proportional control.
KNX PARAMETER
SETTINGS
Delay between Speed Changes (Sec.)
1… 255
This parameter set the pause time between the switching off the relay which control one speed
and the switching on of another relay to activate the next speed
Object type for speed control
3 x 1 bit objects
1 x 1 byte object
This set the data type for the speed control.
Object type for speed status
3 x 1 bit objects
1 x 1 byte object
This set the data type for the speed feedback to be sent on the bus.
Delay on ventilation start (min)
0 … 15
This parameter has effect only in heating mode and introduces a time delay between the
reception of a command which starts the fan speed and the real starting time in order to avoid to
blow cold air instead of warm due to the fact the hydraulic system need a certain time to supply
the hot fluid to the fan coil.
The delay, however, is introduced only when the fan coil actuator activates one of his speeds
starting from the state of no active speed (S1, S2, S3 are all off).
