7-3-2. Maximum Current Value Change Function
The maximum current value is changed to 15.0A or 13.5A to prevent power breaker tripping.
(It is set to 20A when the unit is delivered from the factory.)
1. When the high load is given (Outside temperature is high in the cooling operation, or
NOTE
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
