Introduction
The KL08NSB 24V wiring centre forms the heart of a Underfloor Heating controls system. It allows
easy and quick connection of thermostats and actuators. It has integrated pump and boiler control
module and overload protection. KL08NSB 24V wiring centre is adapted to work with NC and
NO type actuators (normally closed and normally open). Up to 8 thermostats can be connected
to the KL08NSB 24V, while KL04NSB 24V extension allows to connect additional 4 thermostats (12 in
total). NOTE! 24V/230V transformer is included with the set with the control box!

1. Fuse
Note: Replace the fuse only when the wiring centre is disconnected from power supply
(24 V ~).
Main fuse is located under the housing cover next to power supply terminals and secures the wiring
centre and the devices connected to it. Use ceramic tube fast blow 250 V ROHS fuses (5x20 mm) with
nominal max current 12,5 A. To replace fuse remove the fuse holder with a flat screwdriver and pull
out the fuse.

3. NSB (Night Set Back reduction) function and thermostats grouping
NSB function is activated in non-programmable Salus thermostats of the Expert NSB, HTR, BTR
series via external signal. NSB 24 V signal (night-time temperature reduction) is sent via an external
timer or programmable thermostat connected to the KL08NSB 24V 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 mm
