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
4 5
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.
5.10 Remove the front plate of
the TRTWIFI using a screw
driver to press down the
tab on the top
of the device.
5.11 If required, use the
surface mount box
supplied, as a template
to mark the position of
the mounting screws.
Drill the mounting holes
taking care to avoid any
joists, electrical cables
or water/gas pipes that
may be hidden beneath
the surface.
5.12 Insert the rawl plugs into the holes that have been drilled.
5.13 Connect the two white coloured wires from the flex of the power box
5 6
to the TRTWIFI. The wires are not polarity sensitive. If there are 3 wires,
then omit the neutral (blue) wire.
5.14 Re-fit the front of the TRTWIFI by hooking the lower edge over the tab,
and pressing the top home until it clicks, taking care not to bend
the 8 connecting pins.
5.15 Reconnect the mains supply
to the wiring centre.
