will resume, but in 3 minutes of compressor standby, alarm will exist.

13. Jumping frequency point design

Avoiding the frequency point of pipe vibration, we design the jumping frequency function.
13.1 4 jumping frequency points F0; 1 jumping frequency range ∆F.
13.2 The point value and the jump rang will be saved in EEPROM.
13.3 Output frequency will be changed under the below conditions:
In speed up/down period, jumping frequency function does not work, only after the frequency is
steady, if the output frequency is in the jumping frequency range, this function will work, so the final
output frequency is (jumping frequency point value-jumping frequency band)

14. Time shorting function

As long as one indoor unit is in time shorting, the outdoor will enter 1/60 second time shorting
function.
15. Oxygen generator control
Entering condition:
15.1 Oxygen request from indoor unit
15.2 Ambient temperature over 4℃
Quit condition:
15.3 No oxygen request from indoor unit
