NOTE
The ICT is also monitored during COOL and DRY modes, 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.
