Technical Information
The KL04NSB is an easy to connect four zone extension for the KL08NSB wiring centre. It expands
the system to up to12 zones in total
The Serial connector is used to connect the KL08NSN with the KL04NSB extension module to add
functionality and support up to12 zones
NSB function is activated in non-programmable Salus thermostats of the Expert NSB, HTR, BTR series
via external signal. NSB 230 V signal (night-time temperature reduction) is sent via an external timer
or programmable thermostat connected to the wiring centre. Non-programmable thermostats are
receiving NSB signal and reducing setpoint temperature (by switching to eco mode). All thermostats
have to be connected using a 4-wire cable (min. 4 x 0,75 mm2, max. 4 x 1,5 mm2).

is common for thermostats
from Group 1, Group 2 and

common for thermostats
from Group 1, Group 2
and Group 3 (one external
clock + daily regulators e.g.
VS35).
