MIX Mode
The MIX mode is enabled, when the fan has attained the maximum speed

In the MIX mode the compressor can be switched on according to its winter start temperature or the CW valve
can be opened according to its parameters. The ECO louvers (fresh air/exhaust air) are completely opened.
The fan runs with maximum speed

In units with speed-controlled compressor the MIX mode can also be triggered by the start of the speed-con-
trolled compressor, as the compressor is not locked during FC and EFC mode. When MIX mode is triggered
by the start of the speed-controlled compressor the fresh air louver will be opened 100% and the fan speed
will be increased to the maximum speed.
