Serial connector

The Serial connector is used to connect the KL08NSN with the KL04NSB extension module to add functionality and support up to12 zones

Power Supply

The power supply for the wiring centre is 230 V ~ 50Hz.
Two-wire installation should be made in accordance with the applicable regulations

Connection indicator

After successful connection of KL08NSB with KL04NSB extension module red LED will light up constantly.

Power indicator

After connecting KL04NSB to the power supply, the Power red LED will light up.

NSB (Night Set Back reduction) function

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 signals 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 ).

• OPTION 1
  One Master thermostat which is common for thermostats from Group 1, Group 2 and Group 3 (one programmable thermostat e.g. VS30, other thermostats are programmable e.g. VS35).

• OPTION 2
  Three Master thermostats.
  One for Group 1, one for Group 2 and one for Group 3 (three programmable thermostats e.g. VS30, other thermostats are nonprogrammable e.g., VS35).

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

• OPTION 4
  Three external clocks. One for Group 1, one for Group 2 and one for Group 3 (three external clocks + nonprogrammable regulators e.g. VS35).

Note: Terminals 1-4 and 5-8 are located in the KL08NSB wiring centre, while terminals 9-12 are located in the KL04NSB 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 one. Should more than 6 actuators be required in a zone using an additional relay to relieve the output?

Thermostats connection

• Connecting EXPERT NSB, HTR or BTR series thermostats
  

• Connecting a 230 V thermostat (e.g. SQ610 Quantum Thermostat)
  

• Connecting ON/OFF battery-powered thermostat with voltage-free COM / NO output contacts (e.g. 091FL, RT310, RT510)

Note: In NSB, HTR, ERT, BTR product series follow interchangeable signifying:
↑=SL
= NSB

INSTALLATION

Remove the top cover of the wiring centre extension and unscrew the main housing.

Mount the backside of the housing o 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 centre extension and connect them to the terminals.

Adjust the wires and screw the main housing of the wiring centre extension to the rear housing.

Connect the thermoelectric actuators wires.

Connect the serial cable to the KL08NSB and KL04NSB connector.

Make sure that all the wires are properly connected, mount the top cover and power up the wiring centre and wiring centre extension- “Power” and “Connection” red LED diodes will light up indicating the correct connection with the KL08NSB wiring centre.
