DESCRIPTION OF ALARMS

HIGH PRESSURE ALARM:
is automatic until the
interventions/hour equals the value
set in parameter AL7, in which case it
switches to manual. In this case resetting
takes place via the keypad, by pressing
the SET button, once the external cause
has disappeared.
The intervention causes the machine to
switch off and the label E01 to appear
on the display.
LOW PRESSURE ALARM:
is automatic until the
interventions/hour equals the value
set in parameter AL2, in which case it
switches to manual.
When the compressor starts up, this
alarm is concealed for a period equal
to the value of parameter AL1.
Resetting takes place in the same way
as for the High pressure alarm.
The intervention causes the machine to
switch off and the label E02 to appear
on the display.
S1 PROBE FAULT ALARM: this is activated
if probe S1 (boiler water probe) is short-
circuited or cut off.

switch off and the label E03 to appear
on the display.
S2 PROBE FAULT ALARM: this is activated
if probe S2 (outside air probe) is short-
circuited or cut off.
The intervention causes the machine to
switch off and the label E03 to appear
on the display.
HIGH TEMPERATURE ALARM: resetting
takes place automatically.
activated if probe S1 assumes values
over parameter AL5 for a time period
exceeding parameter AL6.
The intervention causes the machine to
