Controller Offline	Power cycle needed
Chlorine not dosing/ Chlorine Low	Chlorine Barrel/Container is empty Chlorine injector is clogged Probe Failure Setpoints not set correctly Stenner needs a new tube Dosing limit to low Power cycle needed
Acid not dosing/ pH High	Acid Barrel is empty Probe Failure Setpoints not set Correctly Stenner tube needs replaced Dosing limit to low Power cycle needed
Probe Failure Controller not reading the correct numbers	Probe Unresponsive Probe needs cleaning Probes needs replaced Power Cycle needed Need to change cap & gel (ppm only)
Chlorine too high	Setpoints not set correctly Wrong feed mode set consider Proportional PWN Too much chlorine going through Stenner- turn down percentage Dosing limit too high Adding chemicals by hand
pH too low	Setpoints not set correctly Wrong feed mode set consider Proportional PWN Too much acid going through Stenner- turn down percentage Dosing limit too high Adding chemicals by hand. Alkalinity not within limit
No Flow	Adjust sample flow valves to allow more flow Backwash/clean filter if necessary Clean controller pre-filter

All these can be done on site with the controller. If you are still having problems- a replacement part may be needed.
