Panasonic CS-KE36NKU Maximum Current Value Change Function, Description of function, CU-KE36NKU

Maximum Current Value Change Function

The maximum current value is changed to 14A (for CU-KE30NKU) or 17A (for CU-KE36NKU) to prevent power breaker tripping. (It is set to 24A (in cooling) or 22A (in heating) when the unit is delivered from the factory.)

NOTE 1. When the high load is given (Outside temperature is high in the cooling operation, or outdoor temperature is low in the heating operation), the capacity is reduced.

When the maximum current value change function is to be enabled, make sure to receive the approval of the client.

2.The maximum capacity for cooling or heating operation is about as much as the rated capacity.
