5. Installation

5.1 Ensure the mains supply is switched off and the circuit supply fuses

are removed or the circuit breaker turned off.

5.2 Disconnect the mains supply from the wiring centre.

5.3 Mount the power box next to the wiring centre (where fitted),

or the boiler.

5.4 Use the power box as a template to mark the position of the mounting

screws. Drill the mounting hole taking care to avoid any joists, electrical
cables or water/gas pipes that may be hidden beneath the surface.

5.5 Insert the rawl plugs into the holes that have been drilled and align the

power box with the mounting holes. Then insert the screws and tighten
until a firm hold of the power box is ensured.

5.6 Connect the live (brown) and neutral (blue) wires on the power box

to a 230V AC supply from the wiring centre, making sure the polarities
match up accordingly with the wiring centre. Refer to the connection
diagram (section 6) for reference.

5.7 Remove the connections from the existing thermostat from the wiring

centre. If there is a neutral connection (blue) this is no longer required
for the installation and must be disconnected. Refer to the connection
diagram (section 6) for reference.

5.8 Connect the existing thermostat connections in the wiring centre to the

two black wires from the power box flex marked boiler. These are volt
free connections, and are not polarity sensitive. Refer to the connection
diagram (section 6) for reference.

5.9 Connect the previously removed wires that go from the wiring centre

to the thermostat to the white wires from the power box, marked
thermostat. The wires are not polarity sensitive. Remove the existing
thermostat if fitted. Refer to the connection diagram (section 6)
for reference.
