centre e.g. a circulating pump.
Terminals
L2
and
N2
are the 230V~ powered
outputs for connecting the circulating pump.
Terminals
NO
and
C
are the output for the boiler
control. This is a voltage free contact (i.e.
unpowered) so that they can be used for boilers
with different voltages.
Through terminals
L1
N1 SWL NSB
a 230V~
external timeswitch (optional) can be connected to
the wiring centre. Terminals
L1
and
N1
are the
powered outputs for the timeswitch power supply,
while
SWL
and
NSB
are the lines provided for
powering the actuators and thermostats section.
For complete control of each of the available
channels the user must connect a 230V~ actuator
to terminals
L1
and
N1
and a 230V~ thermostat to
terminals
NSB SwL< SwL> TN TL
. All outputs of
the actuators and thermostats section are 'powered'
outputs, i.e. they do provide the voltage for the
device connected to them.
Note: Each of the eight wiring channels has
terminals for one thermostat and one actuator only.
Up to five actuators can be connected to a channel
by using a loose cap terminal, code U9360030,
available from Emmeti UK Ltd.
