Setting conditions
This function is used to prevent
the decrease of discharge
air temperature in cooling
operation, by controlling
Thermo-ON/OFF according to
the discharge air temperature.
When ambient temperature >
setting temperature:
If air outlet temperature ≤ 11 ºC
for 3 minutes, the system is
switched to Thermo-OFF.
In this status, if air outlet
temperature ≥ 13 ºC, the system
is switched back to Thermo-ON.
Use at 00 conditions
This function prevents the
occurrence of an excessively
cold air flow in heating mode
by decreasing the fan speed
during heating operation, also
taking into account the setting of
function C5.
This function saves energy
when the outdoor temperature
is lower than the air conditioning
load.
The indoor unit is set to cooling
Thermo-OFF when:
Tout (outside ambient
temperature - out of the building)
< Tin
This function is used to set the
minimum opening angle of the
damper for fresh outdoor air.
