This function can detect a possible lack of power
from the boiler and therefore possible anomalies
of certain componants. This function is generaly
not activated when the power limitation function
of the boiler is activated.
FLOW (F)
(Available only on SCR model)
The
flow
alarm is triggered when the theoretical
flow calculated from the water input and output
temperature differential (max.50F) is above the
authorized flow limit.
This condition triggered by a lack of flow does not
turn off the boiler but activates a yellow indicator
light as long as the condition is active.
CURRENT (A)
The
Current
alarm is triggered when there is a
difference of more than 20% between the
measured current
and the calculated theoretical
current. This may indicate an electrical problem
from a wrong connection.
This condition triggered by a lack of flow does not
turn off the boiler but activates a yellow indicator
light as long as the condition is active. If more
than 50% of the stages are detected as defective,
the alarm will then shut down the boiler and the
red light will light up.
HL TEMPERATURE (HL)
The outlet temperature of the boiler is above the
high limit allowed. This alarm triggers the
deactivation of the heating elements of the boiler.
The boiler is restarted when the temperature
drops below the high limit (and the set-point)
If the boiler is in this alarm state for more than 60
minutes or the condition occurs 3 times in an
hour, the boiler switches to
Lock Out
mode.
LOW PRESSURE (P)
The
Low-Pressure
alarm
“
P
” is activated when
the pressure inside the boiler is below the allowed
limit (default: 5 psi).
This condition triggered by a lack of flow does not
turn off the boiler but activates a yellow indicator
light as long as the condition is active.
HIGH PRESSURE (P)
The
High-Pressure
alarm is activated when the
pressure inside the boiler is above the allowed
limit (depending on the maximum boiler pressure)
BATTERY LOW LEVEL
The low-level battery alarm appears when the
battery used by the internal clock is at a low level.
The battery needs to be replaced. To get the
replacement procedure, contact our technical
service.
LOCK OUT
Lock out mode is activated after 3 major alarms
(red indicator light) have been activated within
one hour or when a major alarm (high limit output
water temperature detected by the external
temperature sensor or low water level condition)
is maintained activated during the same time
period. When the lock mode is activated, the
boiler is deactivated and can only be restarted by
restarting the boiler (to the left of the control
panel) or by using the reset Lock Out function (in
the alarm setting menu). The details of this menu
can
be
found
in
