Connecting the flow meter
For units manufactured in 2020 or later, a power switch can be mounted on the unit.
On the circuit board with the display, the "FS" connector is located at the bottom left.
These are connected to the two contacts of the power switch.
If no flow rate is detected, neither the acid nor chlorine pump runs and an alarm is triggered.
Connect the level switch
For units manufactured in 2020 or later, 2 level switches can be mounted on the unit.
On the circuit board with the display, the connections "WLH" and "WLL" are located in the
middle and bottom right. These are connected to the 2 contacts of the level switch. Connect the
WLH connection to the level switch in the acid tank and the WLL connection to the level switch
in the chlorine tank.
When a low level is detected, the pump involved stops pumping and an alarm is generated
Table 1
The following table shows the ratios between mV, pH and the corresponding chlorine content in
ppm. For example, your device has the following values on the screen: pH 7.2 and ORP of 740,
then your pool water has a chlorine content of 1.2 ppm.
Attention: this table is not always correct. Products such as flocculants, wall cleaners, settling
agents, sulfates, copper sulphate, extreme shredder (Chloramines), electromagnetic
interference and/or less than optimal grounding can cause an Rx of 700-750 mV NOT to
correspond to a chlorine content of 1-1.5 ppm. This is often a temporary phenomenon that
mainly occurs with salt electrolysis.
