MALFUNCTION OR
PROTECTION
FAILURE CAUSE AND CORRECTIVE ACTION
E8
Water flow failure
Check that all shut off valves of the water circuit are completely open.
1. Check if the water filter needs cleaning.
2. Refer to chapter WATER CONNECTIONS - Charging water
3. Make sure there is no air in the system(purge air).
4. Check on the manometer that there is sufficient water pressure. The water
pressure must be >1 bar.
5. Check that the pump speed setting is on the highest speed.
6. Make sure that the expansion vessel is not broken.
7. Check that the resistance in the water circuit is not too high for the pump (refer
to "Setting the pump speed" ).
8. If this error occurs at defrost operation (during space heating or domestic water
heating), make sure that the backup heater power supply is wired correctly and
that fuses are not blown.
9. Check that the pump fuse and PCB fuse are not blown.
E9
Suction temperature sensor(Th)
error
1. The Th sensor connector is loosen. Re connect it.
2. The Th sensor connector is wet or there is water in. remove the water, make
the connector dry. Add waterproof adhesive
3. The Th sensor failure, change a new sensor.
EA
Discharge temperature sensor
(Tp) error
1. The Tp sensor connector is loosen. Re connect it.
2. The Tp sensor connector is wet or there is water in. remove the water, make
the connector dry. Add waterproof adhesive
3. The Tp sensor failure, change a new sensor.
Ed
inlet water temperature sensor
(Tw_in) error
1. The Tw_in sensor connector is loosen. Re connect it.
2. The Tw_in sensor connector is wet or there is water in. remove the water, make
the connector dry. Add waterproof adhesive
3. The Tw_in sensor failure, change a new sensor
EE
The main control board of
hydraulic module EEprom
failure
1. The EEprom parameter is error, rewrite the EEprom data.
2. EEprom chip part is broken, change a new EEprom chip part.
3. main control board of hydraulic module is broken, change a new PCB.
H0
Communication error between
main control board PCB B and
main control board of hydraulic
module
1. wire doesn’t connect between main control board PCB B and main control
board of hydraulic module. connect thewire.
2. Communication wire sequence is not right. Reconnect the wire in the right
sequence.
3. Whether there is a high magnetic field or high power interfere, such as lifts,
large power transformers, etc.. To add a barrier to protect the unit or to move
the unit to the other place.
