Hi all - My PB just finished installing my Pool Pilot Total Control system - SWG with acid pump. We are both stumped with an issue. The Ph sensor is giving a false high reading. Acc'd to my TF-100, the Ph in the pool is at 7.2. The PB also got this reading with his drop kit (don't know what brand.) However, the Total Control system is stating that the Ph is 9.88. We found a Ph calibration menu and tried to set it at 7.2 (assuming the system would use know the current water is at 7.2 Ph), but the system would not let us lower it any further than 9.72, but would allow us to increase it to 12.6. Obviously, none of these Ph settings are reasonable or safe for the pool. When we try to lower the Ph calibration by pressing the down arrow past 9.72, the system reads "Ph out of range. replace ORP sensor."
The unit is brand new; I can't imagine the ORP sensor came bad from the factory, but I guess that's possible. What's more likely, though, is that we just can't figure the system out correctly. Does anyone have ideas for how we can get the sensor to read Ph correctly?
Here are my pool test results currently:
FC: 4.0
CC: 0
Ph: 7.2
TA: 80
CH: 250
CYA: 0
Salt: 3100
Temp: 79 degrees
