[2] THERMISTOR TEMPERATURE CHARACTERISTICS
0.1. Temperature properties of indoor thermistors
0.2. Temperature properties of outdoor thermistors
[3] HOW TO OPERATE THE OUTDOOR UNIT INDEPENDENTLY
1. Cooling in 40 Hz fixed mode
To operate the outdoor unit independently, short-circuit the sections indicated by arrows in the diagram below with an adapter, and apply 230 VAC
between (1) and (N) on the terminal board of the outdoor unit. This allows the outdoor unit to be operated in cooling mode independently.
(Do not operate the outdoor unit in this condition for an extended period of time.)
