10.5 Outdoor interconnection unit with Heater
As an optional glass heater can be ordered for the link, the idea is the same what is
used for the cars back window heater. This automated heater turns on and removes
the ice from the front window only below 5 ºC(±2ºC). It turns of only if the
temperature goes above 10ºC. If the heater is in use you will see a small yellow LED
lighting on the power circuit board.

Three versions exist depending on the system configuration. There are no
differences in the connection can be seen below. J1 terminal block is the power
connector for the heater panel. This can be depending on the version 12VAC,
12VDC, or 8,5VDC. This panel senses the temperature based on the sensor glued
to the front window, and turns on the glass heater or turns it off. The sensor is
connected with two black wires to J3 as it can be seen on the picture. The
connection is simple connect one of the black wires into the middle slot on J3 and
the other one right next to it to Sensor 1. The polarity doesn’t make any difference, in
the operation. Please note that one of the black wires must be connected into the
middle slot on J3.
The heating voltage is connected to J2
with a Blue and a Brown cable, this voltage is switched automatically by the PCB.
