Forced Operation Mode; Additional Function - Daikin FTXS09DVJU Service Manual

Control Specification (09/12 Class)
Detail I Judgment by power consumption
When an output frequency is exceeds 55 Hz and the input current is less than specified value, the
adjustment is made for insufficient gas.
II Judgment by discharge pipe temperature
When discharge pipe temperature is ∆ 36°F higher than target value and the electronic expansion
value opening is 450 pulses (max.), the adjustment is made for insufficient gas.
III Judgment by the difference of temperature
When the difference of the temperature is smaller than
