I have an Intellichem managing pH and ORP. There is an acid pump on the left and an Intellichlor connected. Firmware v 1.06. When the system starts-up in the morning I get a failure in Auto Calibration. Screen looks like this:
pH: 6.20 4.34
ORP: 717 401
After pressing “>” the next screen looks like:
High PH X1:0349
Low PH X2:0534
High ORP X1:0717
Low ORP X2:0401
If I restart the system, it starts and operates normally. But for the last 5 mornings, every time it first starts, I get this error.
Can anyone tell me what fail code 04H is and what might be causing it?
Any help is appreciated.
