1. An aircraft window heat controller system comprising:
an Electrical connection supplying a DC power input of 28 VDC in one or more independent busses;
a controller capable to receive 28 VDC power input from the one or more independent busses and to output a DC voltage regulated between 0 and 28 VDC for first and second independent heating elements, output which is regulated according to a sensed temperature, including over-current protection and over-heat monitoring;
power contactors for controlled power supply shut-off made by said controller; and
wherein the first independent heating element comprises an electrical resistance heating element connected to receive controlled power from said controller with an embedded temperature sensor for developing a temperature sensing signal proportional to a temperature sensed for said first independent heating element.
