LiqTec function
The function of LiqTec sensors can be enabled or disabled in this
display. A LiqTec sensor protects the pump against dry running
and too high liquid temperature (266 ° F ± 9 °F).
When the LiqTec function has been enabled, it will stop the pump
if dry running occurs or if the liquid temperature becomes too
high. The pump must be restarted manually if it has been stopped
due to dry running or too high liquid temperature.
Possible settings:
• Active
• Not active.
The number of available displays depends on the pump type. See
below.
