Current sensor measurements
Setpoints
The pH setpoint confi gurati on determines the ti me when acid is added to the system to reduce the water's pH.
The
default value of the pH setpoint is 7.2.
To determine the value of the setpoint to be confi gured, refer to Taylor's balance, see
“4.1.3 Weekly analyses”.

Principle of injecti ng pH into the appliance:
Example of 4 cycles with a setpoint at 7.4 pH and acid regulati on (standard alkalinity):
• pH ≥ 7.55
: 20% injecti on (2 min) & 80% pause (8 min)
• pH ≥ 7.7
: 50% injecti on (5 min) & 50 % pause (5 min)
• pH ≥ 7.85
: 75% injecti on (7 min 30 sec) & 25% pause (2 min 30 sec)
• pH > 7.9
: 100% injecti on (10 min)
