ERROR CODES RELATED TO LOCAL OPERATING TEMPERATURE SENSORS

Error Code Description
L1 4 Local Temperature NTC 1 short circuit
L2 4 Local Temperature NTC 2 short circuit
L3 4 Local Temperature NTC 3 short circuit
L4 4 Local Temperature NTC 4 short circuit
L5 4 Local Temperature NTC 5 short circuit
L6 4 Local Temperature NTC 6 short circuit
L7 4 Local Temperature NTC 7 short circuit
L8 4 Local Temperature NTC 8 short circuit
L1 3 Local Temperature NTC 1 open circuit
L2 3 Local Temperature NTC 2 open circuit
L3 3 Local Temperature NTC 3 open circuit
L4 3 Local Temperature NTC 4 open circuit
L5 3 Local Temperature NTC 5 open circuit
L6 3 Local Temperature NTC 6 open circuit
L7 3 Local Temperature NTC 7 open circuit
L8 3 Local Temperature NTC 8 open circuit
E31 Global Flow NTC short circuit
E36 Global Flow NTC open circuit
E32 Global Return NTC short circuit
E37 Global Return NTC open circuit
Possible Causes and Solutions
- The Local Flow Temperature NTC of the aluminium section is defective.
- The Global Return Temperature NTC is defective.
- The water circulation through the aluminium section involved is insufficient
Note. In the case of more than one NTC failure at the same time, the most important one prevails.
E.g. "E" failures prevail on "L" failures; if "L" codes are equivalent, the code with the lowest first digit prevails; in the case that
the first digits are equivalent, the code with the highest second digit prevails.

L3 1
The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 3 is too high
L4 1
The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 4 is too high
L5 1 The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 5 is too high
L6 1
The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 6 is too high
L7 1 The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 7 is too high
L8 1
The difference between the Global Return Temp. and the Local Flow Temp. of Aluminium section 8 is too high
Possible Causes and Solutions
As for the above mentioned conditions, they can be due to wiring break, short circuit or failure of the NTC involved, or over
heating of the aluminium section.
