HE2 functional relay stuck due to:
- faulty component
the HE2 power terminals on the PCB, replace the PCB.
Internal fault Replace the PCB.
Low heating rate concerning the outlet tank due to:
- incorrect appliance horizontal installation
water pipes are on the right, dismount the product
from the wall and make the proper installation;
- bad placed or damaged wiring
cable is disconnected/damaged, connect/replace it;
- faulty component
between the HE1 fastons is not in compliance with the
nominal value (R ~ 35 Ω), replace it.
Low heating rate concerning the inlet tank due to:
- incorrect appliance horizontal installation
water pipes are on the right, dismount the product
from the wall and make the proper installation;
- bad placed or damaged wiring
cable is disconnected/damaged, connect/replace it;
- faulty component
between the HE2 fastons is not in compliance with the
nominal value (R ~ 53 Ω), replace it.
HE1 probe short/open circuit due to:
- bad placed or damaged wiring/faulty component
the component is disconnected or faulty (sensor/s
values not in compliance with "Sensor Test Table"),
connect/replace it.
HE2 probe short/open circuit due to:
- bad placed or damaged wiring/faulty component
the component is disconnected or faulty (sensor/s
values not in compliance with "Sensor Test Table"),
connect/replace it.
High difference of temperature measured by higher and
lower sensors into the outlet tank due to:
- HE1 probe incorrect positioning
not entirely into the HE1 sheath, place it in the right
position;
- HE1 sensor/s out of tune
(values not in compliance with "Sensor Test Table"),
replace it.
High difference of temperature measured by higher and
lower sensors into the inlet tank due to:
- HE2 probe incorrect positioning
not entirely into the HE2 sheath, place it in the right
position;
- HE2 sensor/s out of tune
(values not in compliance with "Sensor Test Table"),
replace it.
