Fault compensation method and fault compensation apparatus for air conditioner

摘要

When a fault occurs in the setting unit for setting the position of an actuator or when the control unit for controlling a stepping motor actuator goes out of order, the mode switch door cannot be set to a foot mode or the like other than a ventilation mode and a defrost mode. Therefore, when a fault occurs in the built-in contacts of the actuator for driving the mode switch door or when the control unit for controlling the stepping motor actuator for driving the mode switch door goes out of order, another mode position can be set by moving the actuator to a ventilation mode position or a defrost mode position and then reversing it with the moved position as a starting point.
