1. An electric heating blanket control circuit assembly comprising:
- an electric heater adapted for converting electric energy into heat energy;
a sensor adapted for detecting the temperature level of said electric heater and outputting a temperature signal subject to the temperature level of said electric heater;
a controller electrically connected to said electric heater and said sensor, said controller comprising a monitoring circuit and a main control circuit adapted for receiving the temperature signal from said sensor and controlling the operation of said electric heater subject to the nature of the temperature signal received; and
a power adapter adapted for providing power supply to said electric heater, said sensor, arid said controller;
wherein if a temperature detected by said monitoring circuit is outside a user determined range, said monitoring circuit interrupts power to electric heater.
