1. General Introduction
This manual is intended to be used by installers and describes functions and parameters of the
device BO08A01KNX – Din Rail 8 Output Module and how is possible to change settings and
configurations using ETS software tool.
2. Product and functional overview
The BO08A01KNX module is designed to be installed on a DIN rail and to be used in Home and
Building installations (i.e. offices, hospitals, hotels, private houses, etc...).
Device 8 outputs on board can be configured in different ways:
Each output can be configured independently for load control (R1 to R8)
Each output can be configured independently for ON / OFF or continuous switching
(PWM) for Electric valves (solenoid actuators) (EV1 to Ev8)
Outputs can be configured in pairs for the management of roller shutters and blinds; up
to 4 channels (Channels A to D)
Outputs can be configured in pairs for management of Motor Reductor or for solenoid
valves with 3-point control or for ventilating grilles; up to 4 channels (Channels A to D)
Fan Coil Actuator for 2/4 pipes systems for Heating / Cooling with 3 speed motors) (
relays from 1 to 5)
Different configurations can exist simultaneously on the same device as long as they do
not use the same outputs (relays), for example you can set the following configuration:
Relay 1 to 5 Fan Coil Actuator
Out 6 Generic load managment
Out 7 ÷ Out 8 Shutter management (Channel “D”)
Scheme of all possible configurations for each output:
Relay Generic
Load Fan Coil Act. Shutter / Blinds Electric Valves Motor Reduction
Out 1 R1 On / Off Heating Channel A EV 1 Channel A
Out 2 R2 On / Off Cooling EV 2
Out 3 R3 FanCoil speed 1 Channel B EV 3 Channel B
Out 4 R4 FanCoil speed 2 EV 4
Out 5 R5 FanCoil speed 3 Channel C EV 5 Channel C
Out 6 R6 - EV 6
Out 7 R7 -
Channel D EV 7 Channel D
Out 8 R8 - EV 8
The physical address, group address and parameters are assigned and programmed with ETS tool
software. In order to commission the device, a PC with ETS2 version V1.3 or higher is required as
well as an interface to the bus, (RS232, USB, etc...)

2.1. Address and associations limits
The maximum number of group addresses allowed for the device is 50 this means that
it is possible to associate the communication objects to a maximum of 50 group
addresses.
The maximum number of logical associations allowed for the device is 63; this means
that the maximum number of logical connections between communication objects and
group addresses is 63.
Caution: there is a limit to the number of associations that can be created, on the same
device, between transmission communications objects (i.e. inputs) and receiving
communication objects (i.e. outputs). If you want, on the same device, add a group
address already linked to a transmission communication object (input) to a receiving
communication object (output) which already has a different group address associated,
please note that you can add a maximum of 13 group addresses of this kind for the
whole device.

3. General Parameter Configuration
3.1. Parameters
General Parameter Configuration Page list generic parameters which affects all output channels,
or their selection applies to all contacts of the input device simultaneously regardless of the
function selected later for each.
KNX PARAMETER SETTINGS
Delay on Power-up (3-15 sec)
2 ÷ 15 seconds
Through this parameter is possible to set the delay of transmission of telegrams after a power on
by selecting the time by which the device is allowed to send telegrams.
In large systems after a power failure or shutdown this delay avoids to generate excessive traffic
on the bus, causing slow performance or a transmission block.
If there are different devices that require sending telegrams on the bus after a reset, these delays
must be programmed to prevent traffic congestion during the initialization phase.
The input detection and the values of objects are updated accordingly at the end of the
transmission delay time
At the end of ETS programming the device behaves like after a power on.

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).

6.2. General Parameters
KNX PARAMETER SETTINGS
Contact type

NO – Normally Open
NC - Normally Close
With this parameter you can set the operating mode of the relay. The relay can be used as "open
contact" or "close contact"; This difference is logical because the relay has only one pole and it is
not available a terminal connected to the NC contact.
OUTPUT (Relay status) NO – Normally Open NC – Normally Close
ON (Activated) NO contact is closed NO contact is open
OFF (Deactivated) NO contact is open NO contact is closed
KNX PARAMETER SETTINGS
Behaviour on power down

ON
OFF
STOP – no movement
When bus voltage fall down under approximately 18V device enters the power down routine and it
is possible to set the status of the relay status (See note 1).
Behaviour on power up

ON
OFF
Keep status on power down
On power up it is possible to set the status of each relay with this parameter (see note 2)
NOTES:
[1]:the device has to accumulate the energy it needs to switch the relays when it is on and
stores it into capacitors. For this reason, when a power down is detected, the device has
the energy to switch all the 8 relays only if it has been powered from at least 60 seconds
and it has not done a full 8 relay switch from at least 20 seconds. It is strongly
recommended not to select a full 8 relay switch on power down because the full switch
cannot be done in all the situations.
[2]: When is selected the value “Keep status on power down” for the parameter “Behaviour
on power up” it is maintained the state selected on power down unless you have selected
on power down the behaviour “STOP – no movement”; in that case it is maintained the
state active before power down.
