Setting conditions
This function is used to increase the
air supply pressure in the room.
This function selects the enthalpy
sensor input for Econofresh.
Use at 00 conditions
This function delays unit startup with
energy recovery
This function selects the CO2 gas
sensor input for Econofresh.
Use at 00 conditions
This function prevents the
condensation in the unit by keeping
the fan running after the unit
operation has been turned OFF.
Use at 00 conditions
This function stops the fan to prevent
cold draughts or 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 louvre is
set, the louvre will keep operating
in both thermo ON and thermo OFF
condition.)
In case that indoor unit operation is
set OFF by the remote control switch,
under certain conditions the fan is
operated in cycles consisting of 3
minutes of operation at SLow speed
and 30 minutes of stoppage.
Use at 00 conditions
This function decreases speed of the
indoor unit fan during cooling thermo
OFF, to reduce the spread of smells
and humidity.
