NOTE: pH reduce - when the pH level is too high (use of pH minus liquid).
pH raise
-
when the pH level is too low (use of pH plus liqu
id).
3.10 pH reduce / pH raise
The CF Control 100 is delivered with a dosing pump for correction of the pH level. By
default, the pump is set to the control mode pH reduce; however, this can be
changed to pH raise.
3.11 Container empty message

If you use suction lances with a container low-level indicator you can connect these
according to the following terminal diagram:
- Terminal 17-18: empty signal input chlorine
- Terminal 19-20: empty signal input pH corrector
The container low-level indicator must work as normally open contact.
3.12 Sample water deficiency sensor
Depending on the version, the measuring cell is fitted with a float (red) and a reed
contact switch. When the sample water stops circulating, the float drops down and
the CF Control 100 deactivate all dosing processes as well as the heating. The cable
of the measuring cell is connected to input contacts 15/16 (sample water deficiency)
at the works.
When a sample water deficiency occurs, the message "Sample water deficiency" is
displayed by means of an LED that lights after a delay of 10 seconds When the
sample water circulates again, the previous operating mode is restored after 10
seconds. Please note that the switch-on delay starts when the device is switched on
again and that the dosing processes only restart after elapse of this delay.
3.13 Heating / Solar heating
The CF Control 100 has a potential-free two-way contact that can be used for
switching the heating or solar heating on.
