- the corresponding code flashes on the display unit. See table,
- the unit stops if necessary (see table below).

IMPORTANT NOTE:
All work must be carried out by qualified, experienced personnel.
• The alarms are normally reset automatically.
• Caution: the alarms: - HP,
- LP (low pressure),
- Anti-freeze,
- Water flow rate,
have an event counter that shifts to
manual reset if the alarm occurs several times during the last hour.
• The "refrigerating circuit" alarm is reset manually.
• The alarms are reset by briefly pressing the "
ON/OFF" button (1).
• When the alarm is cleared:

Special features of the alarm relay:
-
the potential-free change-over contact (2
A - 230 VAC max.), on the wiring board's terminal strip, originates from the relay
located on this board,
- the relay is actuated in the absence of an alarm (contacts: 5/6 closed and 5/7 open),
-
in the case of alarm or power supply loss, the relay is released (contacts: 5/6 open and 5/7 closed).
