Possible error messages:
■
No Errors
– No registered errors
■
Anode Low
– Reduced size of the anode protector. A check is required.
■
Leakage
– A leakage from the electrical heater to the water heater's hull is
registered. In this case it turns off and the next turning on is possible only after
turning it off from the electrical power panel.
■
No heat
– The heater is on, but the temperature in the water heater is not increasing
■
S1 E1
– A breakdown in the temperature sensor in the bottom section of the water
heater. It is broken or disconnected.
■
S1 E2
– A breakdown in the temperature sensor in the bottom section of the water
heater. It is on short circuit.
■
S1 Frost
– On turning on the power, the temperature of the water in the water heater
is negative and it is possible to be frozen. Must check the tank's wholeness before
turning on the power again.
■
S2 E1
– A breakdown in the temperature sensor in the top section of the water heater.
It is broken or disconnected.
■
S2 E2
– A breakdown in the temperature sensor in the top section of the water heater.
It is on short circuit.
■
S2 Frost
– The temperature sensor in the top section of the water heater registers
negative temperature.
■
S3 E1
– A breakdown in the temperature sensor of the collector. It is broken or
disconnected. Only modes with electrical heating and boiler heating will work.
In
this case the solar installation's circulation pump works constantly to avoid
overheating of the solar collector!!!
■
S3 E2
– A breakdown in the temperature sensor of the collector. It is on short circuit.
Only modes with electrical heating and boiler heating will work.
In this case the
