4.6 “OFA” over-feed protection
Your pH Perfect is equipped with protection to prevent over-feeding in the event there is a problem with the pH sensor, for example. The purpose of this protection, called “OFA” (Over Feed Alarm), is to pause the appliance if it has not reached the set point at the end of the time; set by default at 4 hours (F).
F
The “OFA” over-feed protection functions in 2 steps:
#1:
“OFA alarm”
flashes on the LCD screen after 70% of the OFA programmed time has been used without reaching the set point.
However, the appliance continues running.
#2:
“Stop OFA”
is displayed on the LCD screen after reaching 100% of the OFA programmed time
(4 hours in the original setting). The appliance is then safe.
To cancel this protection and start your pH Perfect, press the “CAL/Enter” button (possible on the
2 steps of the OFA alarm).
