Assembly and installation instructions
Installation of the control unit
Installation/dismantling
Electrical wiring
Connect the KaController to the nearest
Ka
therm
QK according to the
wiring diagram. The maximum BUS length between the KaController and
the unit is 30 m.
• The respective
Ka
therm
QK automatically becomes the master unit in the
control circuit when a KaController is connected to it.
DANGER!
Disconnect the unit prior to embarking on any wiring work!
Only connect the bus lines when the unit is fully disconnected.
DIP switch setting
• The DIP switches on the rear of the KaController should be set according
