4.15 Controls
4.15.1 External electrical controls
The boiler terminals 3, 4 and 5 are for connecting exter-
nal electrical controls such as a programmer, room ther-
mostat, etc. Terminals 3 and 4 are linked together when
the boiler is supplied. If external controls are used, this
link must be removed, and the controls connected
across terminals 3 and 4. Terminal 5 is an additional
neutral connection for external controls.
4.15.2 Connection of external electrical controls
4.15.3 Connection details using an external wiring
centre
The boiler should be connected to the system controls
using an external wiring centre. Fig. 4.15 shows connec-
tion details for a system utilising a 3 port mid position
motorised valve, figure 4.16, 4.17 shows the connection
details for a system utilising two 2 port motorised valves
(Important: the arrowed numbers indicate connection
into the relevant terminal of the external wiring centre).
