1. HC
– SOFTENER
Our HC SOFTENER controllers ensure a regulation and control of operating process and
regeneration of single unit.
Regeneration can be released by different modes. Volume controlled with time priority (e.g. forced
regeneration after 4 days). A hundred percent time controlled with a pre-set regeneration interval.
Quality controlled regeneration, for example in conjunction with a hardness control device that
supplies an external contact input in case of hardness break, is possible as well.
Different VFC outputs are given to control the operation of the softener:
External regeneration release
Salt lack in brine tank
Pressure shortage
The universal VFC output can be programmed for the below functions:
Warn signal
Regeneration active
Brine lack
An additional VFC relay output confirms possible failure records.
Both relay outputs are designed as VFC alternator.
Several VFC-affected outputs are available for power supply and for the approach of possible
additional plant components:
Brine pump
Circulation pump
