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
Function enabled
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
Function activated
