1. Check whether the correct water heater is
selected (3.4.2 "General and electrical specifications").
2. If the correct water heater is selected, fit the correct selection
resistor.
3. If incorrect water heater selected, select the correct one.
If the error cannot be resolved or is persistent, contact your
installation engineer

• Incorrect reference
voltage from the AD
converter.
• EEPROM error
1. Reset controller.
2. Check that the frequency of the power supply is
compliant (3.4.2 "
General and electrical specifications"). If this
is not the case, contact your installation engineer.
3. If the frequency is correct but the error persists, replace the
solar controller.

Error in temperature
sensor T
1
at the top of
the tank.
The two temperature
sensors in the tank
detect a difference of
> 10°C over a period of
at least 60 seconds.
1. Check sensor position and wiring.
2. Reset the controller if necessary. Replace the sensor if the error
persists.

sensor
(2)
.
The two temperature
sensors detect a
difference of >10

over a period of at least
60 seconds.
1. Check the wiring of the dummy 1 and dummy 2.
2. Reset the controller if necessary. Replace the dummy sensor if
the error persists.
