Making the Electrical Connections
Lower the electrical box to gain access to the elec-
trical connections. Push in the tabs P (Fig. 28) on
either side of the boiler and pivot the box forward.
Remove the PCB cover (see Section 18.4 - page
51). Connect the live neutral and earth wires to
the main cable.
Room thermostats or other external control, they
can be connected in place of the link on the termi-
nal block (Diagram A - Fig. 30).
Note: Use only controls designed for voltage free
switching or 24V supply. Do not connect to a 230V
supply, and do not run 230v cables alongside the
low voltage cables.
All necessary settings for room thermostat opera-
tions are described in Section 17 ADJUSTMENTS
