13. Electrical connections Making the Electrical Connections Lower the electrical box to gain access to the electrical 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 terminal 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 operations are described in Section 17 ADJUSTMENTS AND SETTINGS.

13. Electrical connections (continued) - If a remote time clock is to be fitted, using a volt-free switching time clock, remove the link wire and connect the switching wires from the time clock following points above (see also Diagram B Fig. 30). - If using an external time clock and room thermostat, remove the link wire and connect in series as above (see also Diagram C Fig. 30). Live and Neutral connections to operate the clock motor must be taken from a suitable source. Connector 11 (Fig. 30), is used by the mechanical time clock supplied with the boiler or for the optional digital programmer, for fitting instructions, please refer to those provided with the clock or page 28 of this manual.
