6. Boiler control output 11. Thermostats connection INSTALLATION
Boiler output - this is a volt free output (COM / NO) that controls the boiler in
the heating system. The output closes and the boiler turns on but always after
3 minutes after receiving the heating signal from any of thermostats paired
with wiring centre. The output opens and the boiler switches o when the
last thermostat stops sending heat demand (after the time set on the Delay
jumper).
Remove the top cover of the wiring centre.
Remove the appropriate piece of insulation from the wires.
Adjust the wires and screw the main housing of the wiring
centre to the rear housing.
Unscrew the main housing (see picture).
Thread the wires under the mounting belt in the back part
of the wiring centre.
Thread the wires through the slots in the top part of the wiring
centre and connect it to the terminals.
Connect the thermoelectric actuators wires.
Mount the back side of the housing to the wall.
When mounting on a DIN rail, open the hooks on the back of
the housing.
Make sure that all the wires are properly connected, mount top
cover and power up the wiring centre - the red power indicator
LED will illuminate.
Pump output - this is a volt free output (COM / NO) that controls the circulation
pump in the heating / cooling system. The output closes (pump starts) always
after 3 minutes from the moment of receiving the heating / cooling signal from
any of thermostats paired with wiring centre. The output opens (pump stops)
3 minutes after the last demand for heat/cool sent by the thermostat.
Boiler ON/OFF contacts
(according to the boiler’s
manual)
Boiler output is inactive in the cooling mode.

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 use an additional relay to relieve the output.
The Serial connector is used to connect the KL08NSN with the KL04NSB extension module to add
functionality and support up to12 zones.
- It is used to refresh the data, after switching jumpers 4 or 5.
