WARNING
Remember that the pre-alarms are reset automatically, but the alarms must be reset manually.
From software version 3.9.0, the alarms can be reset by means of the remote ON/OFF contact, if this is enabled.
From the ON position, move to OFF then back to ON within 5 seconds to reset the alarms; a maximum of 3 resets can be made each hour via
the ON/OFF contact.
You must first reset the alarms using the "R" button.
In the event of a lack of voltage, the alarms will be reset.

Frequency reduced by overcurrent or overtemperature protection.
The reverse cycle valve could be faulty or blocked.
The input water temperature has exceeded the value of installer
menu parameter (H). There is probably a boiler in the same system.
With the third pre-alarm intervention, the machine goes into lockout.
This pre-alarm indicates the intervention of a defrosting cycle due to
cycle reverse, without respecting the cycle reverse times. The cycle
reverse was prompted by the capacity control threshold being excee-
ded due to the high temperature of the discharge gas (default 130°).
This pre-alarm does not cause the compressor to stop, and there is
no maximum number of interventions.
This pre-alarm indicates a fault in the remote probe, or a problem
in communication with the DHW panel. The alarm is only active if
parameter (8)=4 in the menu with password = 30.
This pre-alarm indicates a fault in the outside air temperature probe
when the DCP is present, or when the machine is a heat pump.
