Management of dehumidification
In order to be able to dehumidify as soon as consent is given by the logic (see the "Activating dehumidification" section in the
"Dehumidification chapter), the request is set to the maximum step.
The flow rate reduction function can be enabled in dehumidification.
If the function is enabled, the fan speed is taken to a fixed value equal to the "Fan Speed when Dehumidif active" speed.
The parameters for enabling the required flow reduction and speed are under "Fan" menu, which can be accessed by entering
the "Service" password.
For the default values, see the parameters table.

Lack of voltage
Description
5 minutes after the event (loss of voltage) has occurred, the alarm
code sent by Mr. Slim 06840 is displayed in the Main menu of the
keypad in the Client main mask.
The alarm is displayed in the form of flashing (for a few moments),
repeated approximately every 5 minutes while the event persists.
This time is defined internally by the Mr. Slim management system.
At the same time, each time the previous alarm is displayed, an
alarm entry is saved in the alarm log of the main unit controller with
code A 062 CLIENT PACIF BOARD SYSTEM ALARM.
On an operation point of view, the moment alarm code 06840 is first
displayed, the Server 1 unit is also automatically forced to OFF,
while the operation of the main unit continues like before the fault.
After the second 5 minutes have elapsed since Server 1 was
switched off, it will resume operation. However, if the Client unit is
still without power, alarm 06840 will reappear and switch it back to
OFF.
The moment power is restored to the Client unit, alarm code A 084
PACIF CONTROL BOARD OFFLINE ALARM is displayed on the
keypad of the main unit. After an internal PAC-IF time has elapsed,
the same will automatically reset and resume correct operation of
the Client unit.
