4.15.2 External electrical controls

The boiler terminals 3, 4 and 5 are for connecting

xternal 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.
