Always switch off the mains before removing the Wiser HubR – and never fit it to a live wall-plate!
NOTE: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Safe electrical installation must be carried out only by skilled professionals. Skilled professionals must prove profound knowledge in the following areas: • Connecting to installation networks. • Connecting several electrical devices. • Laying electric cables. • Safety standards, local wiring rules and regulations. Failure to follow these instructions will result in death or serious injury
Make the wiring connections, as shown in the connection charts, for the appropriate system.
For surface wiring, snap out the cable entry strip on the bottom edge of the wall-plate. The Wiser HubR is double-insulated and needs no earth connection, butan earthing continuity (loop) terminal is provided for convenience.
Note: If there is an existing wired thermostat, it must be completely disconnected, i.e. remove the thermostat wires from the wiring centre - a link must be inserted between the terminals where the thermostat common and call for heat wires are located in the wiring centre.
Numbers with arrows relate to the junction box. * Consult boiler handbook for details of pump overrun wiring. After wiring, clip on the unit and tighten the securing screws. Check the mains input has a 3A fuse, and switch on the mains.
