with a new one.
Faults indicated by the seven-segment display
Error code Error Remedy
E.001
Temperature sensor defective, temperature
reading too low
Check resistance thermometer, conductivity electrode
LRG 16-9 and, if necessary, replace it with a new one.
Check wiring (short circuit, interruption?)
E.002
Temperature sensor defective, temperature
reading too high
E.005
Conductivity electrode defective, measured
value too low
Check conductivity electrode and, if necessary, replace
it. Check electrical connection.
Conductivity transmitter defective,
measuring current < 4 mA
Check conductivity transmitter and, if necessary,
replace it. Check electrical connection.
E.006
Conductivity electrode defective, measured
value too high
Check conductivity electrode and, if necessary, replace
it. Check electrical connection. Check boiler water.
Conductivity transmitter defective,
measuring current > 20 mA
Check conductivity transmitter and, if necessary,
replace it. Check electrical connection.
In the event of a malfunction a MAX alarm will be raised and the continuous blowdown valve is motored
into the OPERATING position.
