Note: for lengths exceeding 50 m and up to 200 m, the connection between KTR
and circuit board of the chiller/heat pump must be made using shielded cable AWG
20/22 (4 wires + shield) and two branching boards (use the KR200 E968573484
KIT) as in the layout shown below.

The connections between board and switch or remote light must be made with
shielded cable (make sure the shield is continuous throughout the length of the
cable) consisting of 2 twisted 0.5 mm² wires and the shield. The shield must be
connected to the earth screw on the panel (on one side only). The maximum
distance allowed is 30 m. Lay the cables far from the power cables or cables with
a different voltage and cables that emit electromagnetic disturbance. Do not lay
the cables close to equipment that could create electromagnetic interference.
