B. Oxygen enrich control overview
Upon receiving ON signal from indoor unit, the outdoor vacuum pump, fan & 2 way valve will operate according to the various
protection control setting.
C. Oxygen enrich protection control (O
2
supply level judgement)
1. Vacuum pump protection
•
Base on outdoor air temp., Comp. top temp., the oxygen supply level is decided.
•
Priority is given to the lower level.
•
Vacuum pump operation cycle time = EOPMPS01.
•
O
2
supply level change only after vacuum pump ON/OFF operation completed 1 cycle time if the new level is higher than
the present level.
•
O
2
supply level change immediately if the new level is lower than the present level (avoid O
2
supply level hunting).
•
Vacuum pump operate with ON/OFF timing according to O
2
supply level except during continuous running required by
freeze-up prevention control (F-2).
E.g. Oxygen supply level change timing (vacuum pump continuous running control, (C-2) not yet activated).
