To allow the Ecocool control to start from a stable condition (room
temperature is near the setpoint), you can set a delay

delay (during which the unit is in DX/CW mode) has elapsed, free
cooling can be enabled according to the conditions listed on the next

* in A/C units with a compressor the MIX
mode can directly commute to the FC
mode, if the compressor stop tempera-
ture is below the setpoint.
