After cleaning with cleaner, up to 9
cleaning sessions can be carried out with
water only until the next cleaning session
with cleaner takes place.

LC PV = limit contactor pH/
ORP (1)
LC C = limit contactor T (2)

Clean = Chemoclean (5)
Neutra controller (6)
Only for A1 = pH.
If neutra controller is selected for Rel1,
only neutra controller is offered for Rel2.
By confirming with ENTER, another relay
function already switched on is switched
off and its settings are reset to the factory
settings.

R266
Select pulse length
or pulse frequency
Len = pulse length
Freq = pulse frequency
Curr = current output 2
Pulse length e.g. for solenoid valve, pulse
frequency e.g. for solenoid dosing pump,
see "Actuating signal outputs" section.
Curr = current output 2 can only be
selected if O2 = Contr.
R267 Enter pulse interval
10.0 s
0.5 to 999.9 s
This field only appears if pulse length is
selected in R266.
If pulse frequency is selected, R267 is
skipped and entries continue with R268.
