B. Simultaneously depress and hold ‘Set Level’ and ‘Re-Set’ buttons.
While they are depressed, press the Mode button.
The display will read ‘LD’ and then turn On.
C. Release the buttons.
D. The controller is now in test mode. Test mode shortens minutes to seconds.
E. Turn the controller Off again to exit test mode.
F. Turn the controller On to return to operating mode.
The last two steps are extremely important since this puts the controller back in
operating mode. If these two steps are not performed the controller will remain
in test mode and it will not operate properly.
6.0 Troubleshooting-
6.1 Chemicals not feeding
* FLOW light on Controller must be illuminated.
Check flow switch (manifold) if light is not on (Section 3.3.3)
* Feeder power and time switches must be in ‘ON’ position.
Check feeder by using alternate power source.
* Factory setting for feed time is 0.6 sec on with 5 minute delay.
Feeders may require longer feed time.
6.2 Displayed chemical level does not correspond to actual level
* Sensor (probe) is not attached connector.
* Sensor (probe) needs cleaning.
* Sensor (probe) needs replacing.
6.3 Set-points not being reached or maintained
*
Factory setting for feed time is 0.6 sec on with 5 minute delay. Feeders may require
longer feed time. If time is too short, set-points will not be maintained. If time is too long,
overfeeding chemicals will occur. Correct time is dependent of multiple factors such as
pool/spa water volume, feeder output, chemical concentration and chemical needs.
* Controllers are designed to maintain set-points. Do not expect Controllers to make
major adjustments—major changes should be done manually.
* Pump/feeders must be large enough to reach desired set-points in a relatively short
time. Automation using controllers may require larger feeder or more concentrated
chemicals than system that uses continuous time controlled feeding (i.e. feeders only).
