Meaning
The Safety Reduction Load LP (low pressure) function is enabled. The internal
fan of the unit and the inverter are controlled to prevent excessively low pressure
in the low pressure section.
The heater cooling post-ventilation is active
One or more compressors are blocked to comply with the start-up times, or the
unit is awaiting regulation
The pLAN network logics activate the unit when the high temperature limit is
exceeded.
The pLAN network logics activate the unit when the low temperature limit is
exceeded.
The pLAN network logics activate the unit when the high humidity limit is
exceeded.
The pLAN network logics activate the unit when the low humidity limit is

The unit considers its local temperature instead of the average temperature to
control the Hot Spot concerned.
The unit considers its local temperature instead of the average temperature to
control the Cold Spot concerned.
The unit is on standby but the fan continues to run at a set speed
The unit forces the cooling demand sent to the PAC-IF cards to minimum and
keeps ventilation at maximum to help prevent the formation of ice on the piping.
The unit is off, but the fans are kept in operation at reduced speed to prevent gas
build-up in case of leaks
Ventilation has been forced to maximum level due to an alarm (no air flow or gas
leak detected) in one of the other units connected to the LAN network
The Mr Slim external unit has been stopped due to an alarm (gas leak detected)
in one of the other units connected to the LAN network
The Direct Free Cooling damper has been opened to maximum level due to an
