3.3 Wiring Layout
All wiring must be carried out in accordance with current IEE wiring regulations. It is
recommended the user interface controller is mounted in an easily accessible location within the
property. The wiring connection to the user interface is via a pLAN connection and must be
wired from the wiring panel to the user interface controller with the supplied CAT5e cable.
The CAT5e cable should be routed separately from the mains cables to avoid interference.
The following section details the connection of the appliance to the user interface controller via
the supplied 20m CAT5e cable. Figure 58 below shows the colour coding of the wiring into the
pLAN terminals. These terminals are located in the Installer's wiring panel at the front of the
appliance as shown in Figure 1 (see page 1). The other end of the cable, with the RJ12 plug
connects into the back of the user interface controller supplied. Max 50m, shielded CAT5e
cable.
All connections are made to the quick-connect type connection block, use an appropriate
bootlace crimp or ferrule to provide a sound connection to the connection block. The solid
brown coloured wire and striped white/brown coloured wire are not to be used and should be
cut back and insulated to the outer sheath of the cable.
The
mains 230V AC 50Hz permanent and switched supplies to the appliance must be fused at
5 amps via an RCD and must be earthed.
A switched live from a time clock or programmer controlled by room thermostats is required to
control the appliance as shown in Figures 59 and 60 below.
Using good quality room thermostats and controls will assist to reduce repeated ignition and
extinguish cycles.
