Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are provided
with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with the manufacturer’s
instructions by a competent person approved at the time by the Health and Safety Executive and that it meets the requirements of
the appropriate Building Regulations. The Benchmark Checklist can be used to demonstrate compliance with Building Regulations
and should be provided to the customer for future reference.
Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code of
Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme.
Visit www.central heating.co.uk for more information.

1 Important Information
The Smart Wiring Centre is a wall mounted state-of-theart eBUS system component which has been designed in
accordance with recognised safety regulations.
It allows the “Climapro or Climapro RF” to communicate
with the traditional 230V zone valves and DHW storage
cylinder. Information about the heat required by the cylinder
is communicated to the heating appliance. The heating
appliance (boiler) then decides whether a hot water request
has to be fulfilled and sends a signal to position the 230V
zone valves.
Any other use is considered to be improper use and the
manufacturer/supplier are not liable for any resulting damage.
The following components can be connected:
230V 3-port mid-position valve
or alternatively
2 x 230 V 2-port zone valves
NOTES:
1. Systems requiring more zone valves or a combination
of 3-port and 2-port valves are not possible.
2. The Smart Wiring Centre requires a 230V supply.
3. The heating appliance (boiler) also requires a 230V supply.
4. The eBUS wiring will not provide 230V from one device to
the other!
● Please read these instructions in conjunction with the instructions supplied with your boiler.
● You MUST conform to all specified safety standards and
regulations within the instructions.
● Follow the instructions carefully for the safe installation of
this kit.
● This kit MUST be installed by a competent person and
unless stated all parts are replaced in reverse order to
removal.

Refer to diagram 1.1. Kit part number 0020059275.
1.3 Recycling
The Smart Wiring Centre kit comprises many recyclable
parts. The packaging and its contents should not be disposed
with domestic waste but disposed of according to the current
regulations.
2 Safety Instructions and Regulations
2.1 Safety instructions
2.3 CE label/conformity
Isolate the mains power supply before working on the unit,
and ensure that the power cannot be accidentally switched
on.
The mains switch on the Smart Wiring Centre is not sufficient
to isolate all terminals of the system or boiler.
We accept no liability for damage caused by improper use.
The Smart Wiring Centre, in connection with the Flexicom or
Ultracom condensation boilers, fulfils the basic requirements
of the following guidelines:
Electromagnetic compatibility directive (Guideline 89/ 336 EEC of the council) Low voltage directive (73/23/EEC).
2.2 Regulations
All wiring must be in accordance with Building
Regulations Part P, IEE wiring regulations (BS7671) and must
be carried out by a competent person.

3.1 Start-up
The initial start-up of the Smart Wiring Centre controls is
carried out together with the initial start-up of the boiler.
NOTE: In the factory settings, the boiler operation is set to
Hot Water priority
1. Flexicom: Press “MODE” and “+” buttons simultaneously
for 5 seconds. The display shows “0”.
Ultracom: Press “MODE” for 5 seconds. The display
shows “0”.
Display
Meaning
0
Warm water priority
- The 3-port valve is in the heating or
hot water position depending on the
operating mode.
- With 2-port valves, either the DHW
valve or the CH valve is open, both
valves are closed on standby.
1
Enable mid position
- The 3-port valve is in the mid position
for simultaneous heating and hot
water request, or in the heating or
hot water position, depending on the
operating mode.
- With 2-port valves, both valves are
open during simultaneous heating
and hot water request. Otherwise,
only one valve is always open and
both valves are closed on standby.
2
Only heating mode (only for test
operation!)
- Only the CH valve is activated.
2. Use the “+” or “-” buttons (Ultracom use the heating control
“+” or “-” button) to scroll through to number 35.
3. Press “MODE”.
4. Use the “+” or “-” buttons to scroll through to diagnostic
number d.70.
5. Press “MODE”.
6. Change the setting using the “+” and “-” buttons. Refer to
Table 1 Boiler settings, for the most appropriate setting for the
specific application.
7. Save the new value by pressing “MODE”.
8. To leave the diagnostic menu press and hold “MODE” until
the running screen is displayed again.
The following settings are possible, see table 1.

3 Instructions for Use
The Smart Wiring Centre MUST BE installed in a dry room.
It can be positioned near to the DHW cylinder. The hot water
and heating programs as well as all required parameters
are set at the Climapro RF programmer. All heating circuit
connections are made at the Smart Wiring Centre using the
plugs supplied.
1. PRESS THE CATCH ON THE UPPER EDGE
OF THE BOX DOWNWARDS
USING A SCREW DRIVER.
2. PULL THE HOUSING
COVER FORWARDS.
4.2 Installation overview
1.
Please complete the following before installing the Smart
Wiring Centre:
Read the installation instructions
Check the Smart Wiring Centre Kit components
Check the electrical installation
Standard wires with a minimum cross section must be used
for wiring:
Power supply 230V (connection cable to pumps or Control Center) 1.5 mm2
Extra-low voltage supply
(sensor or bus wires) 0.75 mm2
DO NOT exceed following maximum wire length:
Bus wire........................300 m
NOTE: Where eBUS cables run in parallel with 230V cable
over a length of 10 m, they must be separated by at least 25
mm.
230V connection leads must be secured with the cable
clamps supplied.
DO NOT use free terminals on the unit as support terminals
for other wiring.

4 Installation
CAUTION: Any existing 230V wiring box installation must be
removed completely.
The electrical installation must be carried out by a competent
person who is responsible for complying with the existing
standards and guidelines.
Isolate the mains power supply before working on the unit,
and ensure that the power cannot be accidentally switched
on.
The mains switch on the Smart Wiring Centre is not sufficient
to isolate all terminals of the system or boiler.
Fit the “Link Wire”, supplied in the Smart Wiring Centre kit to
the electrical cartridge as shown in diagram 4.3.
4.6 Installing the Smart Wiring Centre with
one 3-port valve
Make connection to the Smart Wiring Centre as shown in
diagram 4.4.
Connect the eBUS terminals of the Smart Wiring Centre to the
eBUS terminals of the boiler using a two-core cable.
NOTE: The polarity of the eBUS cable is not important.
The eBUS can be connected in parallel.
The Smart Wiring Centre has a mains switch, see diagram
4.2 to isolate the internal electronics as well as all connected
zone valves for the purposes of tests and maintenance.
When the housing cover has been removed, a green LED
indicates if the Smart Wiring Centre is still connected to the
mains voltage.
The Smart Wiring Centre requires its own 230V mains
supply via a switched fused spur. The boiler also requires a
230V supply.
4.7 Installing the Smart Wiring Centre with
two 2-port valves
Connect the Smart Wiring Centre as shown in diagram 4.5.
Connect the eBUS terminals of the Smart Wiring Centre to the
eBUS terminals of the boiler using a two-core cable.
NOTE: The polarity of the eBUS cable is not important.
The eBUS can be connected in parallel.
The Smart Wiring Centre requires a separate 230V mains
supply via a switched fused spur.
The boiler also requires a 230V supply.
NOTE: The Smart Wiring Centre has a mains ON/OFF switch,
see diagram 4.2 to isolate the internal electronics as well
as all connected zone valves for the purposes of tests and
maintenance. When the housing cover has been removed,
a green LED indicates if the Smart Wiring Centre is still
connected to the mains voltage.
4.8 Unvented hot water systems
It is a requirement that the flow of hot water is stopped should
an unvented hot water cylinder overheat.
IMPORTANT: Both thermostats should be wired to the ‘CYL’
connections in series.
