• Check each performance value in test-run mode. Electrical performance values represent a combined indoor/outdoor value.
• Overload prevention operates to protect the air conditioner when outdoor ambient temperature becomes extremely high in
heating mode. (Refer to "8-2. Protective Functions Overload prevention during heating.")
