Assembly and installation instructions
Description of control, Basic settings
The KaControl version provides the option of controlling the
Ka
therm
QK by
means of a control unit supplied separately or on-site building management
technology.
A number of different settings and configurations are possible using the DIP
switches on the PCB and parameters that can be set by the control unit.
This manual provides only a brief overview. Please refer to the
separate KaControl instruction manual for further setting options.
The KaControl system offers the possibility of grouping, although an
extension board (CANbus), available as an accessory, then needs to be
provided.
Lay control lines separately from supply lines.
Use UNITRONIC® BUS LD 2x2x0.22 or similar as data cables.
Wire the unit in series: star cabling is not allowed.
