A08
Low pressure sensor malfunction
The low pressure sensor detects 0.2 MPa or
less
O
X
1. Hardly any or low water flow rate
2. Flow switch defect
3. Under-load cooling or prolonged defrosting
(heavy frost formation) under the above
conditions
4. Low pressure sensor defect
5. Check the refrigerant circuit (gas leakage)
A09
Overheating protection mode
- If the thermostat on the backup heater
is activated while the heat pump
or backup heater is in operation.
- If operation of the thermostat is activated
despite the fact that it has been stopped
Heating
X
Hot water
O
X
1. No water (heating without water) or no water
flow
2. Flow switch defect
Backup heater defect (fault on thermostats for
automatic reset)
A10
Frost protection mode
(2)
If TC-TWO<-15K in cooling mode
O

X
1. Hardly any water flow
2. Flow switch defect
3. Check water outlet temperature sensor (TWO)
A12
Heating or hot water heating
The frost protection control detects under
the condition of TWI<15°C while TWI≥15°C,
TW≥20°C downstream of the heating
backup is not detected
O
O
1. Activated due to high heating or hot water
supply load
2. Check heating circuit (auxiliary or hot water
cylinder heating)
- Power supply voltage, cut-out, power supply
connection
A13
Pump fault
Heating
X
Hot water
O
X
1. Pump has stopped for various reasons
- Low voltage
- High humidity around the electrobox of the
pump
- Condensation formation on the electric
PCB of the pump
- Switch off the power supply then switch it back
on to operate the system
2. Check the flow switch in the Hydrobox

- Condensation formation on the electric
PCB of the pump
- Switch off the power supply then switch it back
on to operate the system
2. Check the power supply
E03
Error in normal communication
between Hydrobox and remote control
If there is no normal communication from the
remote control for 3 minutes or if no remote
control is connected
X
O
1. Check the remote control connection
2. Remote control defect
E04
Error in normal communication between
Hydrobox and outdoor unit
The continuous signal cannot be received by
the outdoor unit
O
O
Check the series connection
- Miswiring at the crossover point between the
water-to-air heat exchanger and the outdoor
unit
E08
Duplicated address of the Hydrobox
or duplicated master Hydrobox during
group control
X
O
Correct the address number of rotary switch
"SW01" for the Hydrobox
