Controls

(TURBOmax Plus boiler)
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.
6 Terminal 5 is an additional neutral
connection for external neutrals such
as from the anticipator of a room
thermostat.

Fig. I.14 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.
