Assembly and installation instructions
11.1 Overview of controls
The
Ka
therm
QK comes in a series of different electrical versions.
Connect it via a terminal strip in the electrical junction box. This is located
on the side of the
Ka
therm
QK’s water connection.
Wire the unit as per the wiring diagram, which is different for each version.
Ask a qualified electrician to determine the type of cable and cable cross-
sections: The cable cross sections basically depend on the fuses for the cable
length and the wiring capacity of the electric motors on site .
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.
