Technical Information
The KL04NSB24V module is an extension to the KL08NSB24V wiring centre with another 4 heating zones.
It works only in combination with the KL08NSB24V wiring centre and increases the functionality of the
combined set to 12 individually controlled heating zones.
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
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).
One Master thermostat common for Group 1, Group 2 and Group 3 thermostats (one
weekly thermostat, eg.VS30, other daily thermostats, eg.VS35).
One external clock, common for Group 1, Group 2 and Group 3 thermostats (one
external clock, daily thermostats, eg.VS35).
Three Master Thermostats. One for Group 1, one for Group 2 and one for Group 3
thermostats (three weekly thermostats, eg.VS30, other daily thermostats, eg. VS35).
Three external clocks. One for Group 1, one for Group 2 and one for Group 3 thermostats
(three external clocks, daily thermostats, eg.VS35).
