Hi,
I have a Jandy C1900 ORP and pH ChemLink Controller that is around seven years old that has recently stopped recognizing when a new pH calibration number is entered. I am able to enter and save the new number as expected however the system stays on the old inaccurate number and slowly moves around according to pH levels.

I have tried the following to no avail:
- Resetting equipment by completely shutting down power.
- Clearing all memory via the OneTouch screen and reprograming entire system.
- Trying to recalibrate pH from OneTouch, web and iOS.
- Swapping out front board and chip.
- Swapping out pH sensor.
