Introduction
The KL04NSB24V module is an extension to the KL08NSB24V wiring center with
another 4 heating zones.
It works only in combination with the KL08NSB24V wiring center and increases
the functionality of the combined set to 12 individually controlled heating
zones.
Product compliance
Directives: Electromagnetic Compatibility Directive EMC 2014/30 / EU, Low
Voltage Directive LVD 2014/35 / EU and RoHS Directive 2011/65 / EU.

Before performing any activities related to the power supply (connecting cables, device installation, etc.), make sure that the wiring center and the module are not connected to the mains! Installation should be performed by a person with appropriate electrical qualifications. Incorrect wiring may damage the devices. The module cannot be used in conditions of water vapor condensation, nor can it be exposed to water.
Technical Information
| Power supply | From KL08NSB24V wiring center |
|---|---|
| Rating max | 3 A |
| Output | 24V AC thermoelectric actuator |
| Dimension [mm] | 163 x 85 x 67 |
Serial connector
The Serial connector is used to connect the KL08NSB 24V with the KL04NSB 24V
extension module to add
functionality and support up to 12 zones
Connection LED diode
Correct connection of the KL08NSB24V wiring center with the KL04NSB24V module is indicated by a glowing red diode (Connection).
Power LED diode
When the module is connected to the power supply, the red LED (Power) lights up.
NSB function terminals
The NSB function is activated in the Salus Expert series daily thermostats, eg. HTR, by means of an external clock or weekly thermostats of the said series. Daily thermostats, receiving the NSB signal, lower the set temperature (by switching to the economy mode). All thermostats must be connected with a 4-wire cable (min. 4 x 0.75 mm2, max. 4 x 1.5 mm2).
OPTION 1
One Master thermostat is common for Group 1, Group 2, and Group 3 thermostats (one weekly thermostat, eg. VS30, other daily thermostats, eg. VS35).
OPTION 2
Three Master Thermostats. One for Group 1, one for Group 2, and one for Group 3thermostats (three weekly thermostats, eg. VS30, other daily thermostats, eg. VS35).
OPTION 3
One external clock, common for Group 1, Group 2, and Group 3 thermostats (one external clock, daily thermostats, eg. VS35).
OPTION 4
Three external clocks. One for Group 1, one for Group 2, and one for Group 3 thermostats (three external clocks, daily thermostats, eg. VS35).
Note: The 1-4 terminals and 5-8 are on the KL08NSB24V wiring center, and the 9-12 terminals are on the KL04NSB24V extension module.
Actuators connection
The actuator wires should be secured with the self-locking connectors in the appropriate zone. Up to 6 actuators with a load of up to 2 Watts each can be connected to a single zone. Should more than 6 actuators be required in a zone to use an additional relay to relieve the output.
Thermostats connection
-
Connection of EXPERT, HTR series thermostats.
-
24 V thermostat connection (e.g. RT1024V)
-
ON / OFF (battery) thermostat connection with voltage-free COM / NO output contacts (e.g. 091FL, RT310, RT510)
Note: The following symbols are used interchangeably in the NSB, HTR, ERT, BTR series products:
= SL
= NSB
INSTALLATION
Remove the top cover of the wiring center extension and unscrew the main housing.
Mount the backside of the housing to the wall. When mounting on a DIN rail, open the hooks on the back of the housing.
Remove the appropriate piece of insulation from the wires.
Set includes supplementary accessories (to support the installation process).
Thread the wires under the mounting bolt in the back part of the wiring centre extension.
Thread the wires through the slots in the top part of the wiring center extension and connect them to the terminals.
Adjust the wires and screw the main housing of the wiring center extension to the rear housing
Connect the thermoelectric actuators wires.
Connect the serial cable to the KL08NSB 24V and KL04NSB 24V connector.
Make sure that all the wires are properly connected, mount the top cover, and power up the wiring center and wiring center extension – “Power” and “Connection” red LED diodes will light up indicating the correct connection with the KL08NSB 24V wiring center.
