Note:
1. The ICT is also monitored during Cool and Dry mode, in case the RV control circuit is
faulty. Whenever ICT reaches 70
o
c, which indicates a high pressure in the indoor coil,
the COMP will be forced off automatically. The COMP can be turned on again only
after the ICT is under 70
o
c again and after the 3 min COMP ON delay time. The
OPER LED will not blink in this case.
