Making the Electrical Connections
Lower the electrical box to gain access to the elec-
trical connections. Push in the tabs P (Fig. 31) on
either side of the boiler and pivot the box forward.
If using a room thermostat or other external control,
they can be connected in place of the link on the ter-
minal block (Diagram A- Fig. 33).
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
AND SETTINGS.
