Temperature Control Switch Circuit







Circuit Description
By turning the temp. control switch, the set temperature of the A/C can be adjusted in steps of 1 °F (USA) or O.6 °C (Canada). Turning the switch fully will set the A/C to MAX. COLD or MAX. HOT. The ECU calculates the set temperature from the combination of Hi (5 V) or Low (0 V) terminals SET 1-5 of the temp. control SW and displays the set temperature on the LCD display. If a malfunction occurs in the temp. control SW circuit, malfunctions such as not being able to set the desired temperature occur.
