Connection details for external time switches and

boiler terminal strip.

the relevant terminal in the boiler terminal strip.

If a room thermostat is to be connected in addition to a

time switch the wire between the time switch „ON“ ter-

minal and boiler terminal 4 should be broken by the

contacts of the room thermostat (see schematic layout,

5.14 Controls

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 exter-

nal neutrals such as from the anticipator of a room

thermostat.

Fig. I.12 shows the connection details where a pro-

grammable room thermostat (time switch with built in

room thermostat) is used to control the boiler.

Attention!

The arrowed numbers indicate connection into

the relevant terminal in the boiler terminal strip.
