1. Filter switching
Single filter 1
If you enter ‘YES’ the system consists of 1 filter.
Single filter 2
If you enter ‘YES’ the system consists of 1 filter.
The ability to select between ‘Filter 1’ and ‘Filter 2’ allows a two filter system to be
reset quickly to single filter service (for repair work or low water demand).
Alternating service
A two filter system normally runs in alternating mode, with one filter supplying
treated water while the other filter is in reserve (standby) or is being regenerated.
Parallel service
If high output performance is required over a short period, a two filter system can
also be run in parallel. Here both filters supply treated water at the same time
except during a regeneration.
When the controller is programmed for parallel service, it can be switched back
and forward between alternating and parallel modes using the special function
‘Switching from parallel to alternate’.
Valve control for alternate service and parallel service can be entered at 4.1. For
this, the controller must first be programmed for alternate service (1.3 at Yes)
and then for parallel service (1.4 at Yes).
For parallel service you can determine whether the filters are to be regenerated
one after the other or at offset intervals.
If you select ‘Reg.Fi.1+2 Y/N’ both filters will be regenerated immediately one
after the other, since both filters are saturated.
For example: silica filter systems activated by time intervals or differential
pressure gauges.
NOTE: For water softening systems it must be ensured that brine is available
(reservoir tank or separate salt solution container).
If you select ‘Reg.Fi.1+2 Y/N’ only the saturated filter in service will be
regenerated. At this point the other filter still has 50% of its capacity.
For example: Quantity controlled water softening systems at high outputs.
