Description
This function delays unit startup
with energy recovery
This function selects the CO
2
gas sensor input for Econofresh.
Use at 00 conditions
This function forces that the unit
will operate in high speed during
60 minutes after fan start. After
this time the fan will be changed

overheating.
C8 must be set to 01 to use the
E8=01 setting.
The connection of a THM-R2AE
remote temperature sensor to
the THM4 port in the indoor unit
PCB is required. The remote
sensor shall be installed in a
proper place for the correct
detection of room temperature.
(In case that automatic louver
is set, the louver will keep
operating in both Thermo-ON
and Thermo-OFF condition)
