4.17 Controls (ecoMAX 800)
4.17.1 External electrical controls
The boiler terminals 3, 4 and 5 are for connecting exter-
nal 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.
4.17.2 Connection of external controls
4.17.3 Connection details for programmable room
thermostats
Fig. 4.19 shows the connection details where a pro-
grammable room thermostat (time switch with built in
room thermostat) is used to control the boiler.
Important:
The arrowed numbers indicate connection into
the relevant terminal in the boiler terminal strip.
