Notes:
1. Protection Mode is activated when any of the condition A or condition B is satisfied.
•
In OCT high pressure protection, only the system that start the protection is under the
control of the protection routine. The other system will continue to work in normal
mode.
2. The OCT HP protection is triggered by the measured OCT-A (or OCT-B) only. The status of the
RV & CO inputs from the indoor units are not checked. This way, the protection can also handle
the abnormal situation caused by hardware failure, such as RV or COM output relay is defective
and
3. If the OF speed is marked as “Hi/Lo”, its speed is governed by the outdoor air thermistor as
explained before.
