Table 4.1 Vaillant controls and accessories
4.15.2 External electrical controls
The boiler terminals 3, 4 and 5 are for connecting
external electrical controls such as a time switch and/or
room thermostat. 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 neutrals such as from
the anticipator of a room thermostat.
