XII.Appendix
For most controller applications, the continuous feed mode is
appropriate. However, if you are using the controller in one of
the following situations, you may need to change the controller
settings to allow for a timed feed cycle followed by a delay cycle:
•
Using a peristaltic pump to feed the sanitizer or pH and you
are experiencing overfeeding
•
Using an erosion feeder with a spa or small body of water
and you are experiencing spiking
•
The ORP sensor is located downstream from the introduc-
tion of the sanitizer (the pH sensor should always be located
upstream from the introduction of the pH balance)
•
With a Watermatic G-1000, G-1000A or G-7500 feeder
Once you have chosen the appropriate feed and delay cycle
times from the following pages, allow the system to run for a few
days. Then adjust the feed cycle longer if the water is undersan-
itized, and adjust the feed cycle shorter if the water is oversani-
tized. You can also shorten the delay cycle if the feeder cannot
keep up with the demand.
The ORP and pH sides of the controller can be modified inde-
pendently. For example, the pH side can be left in continuous
mode while the ORP side is set for a timed feed and vice versa.
This versatility means you can choose the optimal settings for
your controller application.
