7 - FAULT LEVEL (MENU 6)

Each type of fault can be forwarded to one of the following two changeover contact relays:
- Non-critical fault relay.
- Critical fault relay.
This menu is used to configure which type of fault will be forwarded to which relay (critical or non-critical).
No. Description
N02 No air flow (*)
N03 Fan (*)
(Condensation unit
N04 Low pressure for each circuit
High pressure or circuit breaking for each circuit)
N05 Filtration fouled
N06 Filtration blocked (*)
N07 Temperature sensors (10 KΩ)
N08 Electric heater
N09 Humidifier
N11 Water leak
N13 Temperature set high
N14 Temperature set low
N15 Relative humidity set high
N16 Relative humidity set low
NOTE:
- Faults marked (*) shut down the machine
- If the master/slave function is used, the faults defined as critical will stop the unit.

8 - WEEKLY PROGRAMMING (MENU 5)

This menu is only accessible if at least one timer channel is used. Only the configured channels are displayed. The two channels can
be programmed over a week. Each day can have different time schedules. Each channel can have twenty different programmes.
A program includes the hours and the days for activation and deactivation of the channel.
TIMER CHANNELS:

8.1 - Ventilation on sub-menu 5.1

This menu is only visible if P01 = 2 is configured.
When the channel is activated, the fan is authorised to start up. (To ensure this channel is active, check that no shunt has been created
on terminals 1 and 7 of terminal block J2).

8.2 - Shifting the temperature setpoints (sub-menu 5.2)

This menu is only visible if P31 = 2 or P32 = 2 is configured.
When the channel is activated, the setpoint shift is activated.
