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.

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.

4.4 Installing the Smart Wiring Centre
Position and mark the 2 fixing holes and drill the holes, see diagram 4.2. Select the wall plugs and screws to suit the wall construction then secure the housing to the wall. Make connections to the Intelligent controls wiring kit as described in the paragraphs 4.5 to 4.7. Fix all cables using the cable clamps. Finally, press the covering back onto the housing so that it clicks into place.

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.
