2.1.5 System capacity (C)
Not viewed in time clock mode
This setting is identified by the letter C. The system capacity is in m
1000.
The setting range is
The system will calculate the water volume that needs to be treated before a regeneration is
requested referring to this parameter and the following one.
Eg. : 99.9 x1000 l x °tH or 99.9 m
Eg. : 100 x1000 l x °tH or 100 m
2.1.6 Feedwater Hardness (H)
Not viewed in time clock mode
This setting is identified by the letter H. It enables the regulation of the feed water hardness. The
system uses this setting and the previous one to establish softened water capacity.
ex.: 35°tH
2.1.7 Reserve type (RS)
Not viewed in time clock mode
- Safety factor: this parameter is identified by the letters SF. The value is expressed as a
percentage of the capacity of the softened water that the system must keep in reserve. Any
change to the system capacity or inlet water hardness will affect the softened water capacity
calculated by the system and therefore the reserve volume.
The maximum setting is 50%.
ex.: - 15% of the reserve capacity
- No reserve, set on zero
- Fixed reserve: this parameter is identified by the letters RC. This setting is expressed in volume,
the unit depends of the parameter set during the programming. The maximal volume which can
be used as reserve is one half of the softened water capacity calculated by the system. This fixed
reserve is not affected if the parameters "system capacity" or "inlet water hardness" are
changed.
ex.: - 1200 litres in reserve
- No reserve, set on zero
Note:
If parameters system capacity (C), water hardness (H) or reserve (S) have just been modified
during programming, the circuit board recalculates the system capacity.
2.1.8 Day override (DO)
This parameter is identified by the letters DO. It allows to set the maximum amount of days that
the system can stay in service mode without a regeneration. The setting of this parameter is
mandatory in time clock mode and optional in volumetric mode.
Note: the electronic will need at least one regeneration day activated to log out of the
programming mode.
ex.: - Regeneration every 7 days
- No override
