ADDITIONAL REGENERATION

ration» key for five seconds then release. This action will not modify any setting and the microprocessor will
take it into account for the next calculations.

This emergency stop mode will return the softener to the service position. If the stop was
made during the passage of brine or rinses, the brine may be dragged to downstream installations of the
softener.
To perform this type of stop : press the «R» and «Mode» keys simultaneously then release.
CONTROL OF AN EXTERNAL PUMP
A 24 volt contact is available on terminal V4 of J23 to control a dosing pump when the softener is not in
regeneration.
