Tips on troubleshooting
The following troubleshooting approaches may help in the event of faulty operation, but before work -
ing on the freshwater module, it is always important to ensure that it is at zero volt and that no hot
pipe temperatures can occur.
Other possible solutions:
• Check temperature sensors (sensors and wiring)
• Check cable connection between controller and flow sensor
• Check water pressure on secondary side
• Check flow sensor for contamination
• Check position of set value adjuster (may be twisted by 180°)
