4.17 Controls (ecoMAX 800)

4.17.1 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.

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 programmable 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.
