PH STABILITY
WHAT IS IT?
It's a control that DUAL performs when it is switched on that allows the system to stabilize the pH before
dosing the chlorine.
In fact, if pH stability is setted (Yes), at the power on, DUAL waits that the pH measure reaches the desired set point before
starting the programmed dosing on the CL pump.
However, there is an extra control that DUAL performs: if after 1 hour the pH doesn’t stabilize, DUAL unlocks the dosage of
the CL.
The pH stability control is automatically excluded if pH or CL has been programmed in manual type.
