ORP Control Mode
Click on the radio button of the option that matches your installation:
Direct ORP Sensor should be selected if you will be controlling the ORP relay based on a signal
from an ORP electrode.
Direct ORP Sensor with Spike should be selected if you want to control the ORP relay to a lower
ORP set point for most of the time, and occasionally control to a higher set point for a defined
period of time.
Other (4-20 mA input 7) should be selected if you will control the ORP relay based on a signal
from a transmitter that is connected to 4-20 mA input 7. This option is only possible if your
controller is equipped with the analog input option card.
Water Meter Selection
Click on the radio buttons of the options that match your installation:
Makeup Let the controller know if you have a makeup water meter connected, and if so, which
type, contacting, paddlewheel, or 4-20 mA. Up to three makeup water meters may be used. If you
have more than one makeup water meter, the digital input option is required. If you have any 4-20
mA style meters, the analog input option is required.
Bleed Let the controller know if you have a bleed water meter connected, and if so, which type,
contacting, paddlewheel, or 4-20 mA.

Click on the radio button of the method of addition that you want to use for Biocide 1:
Not Used should be selected if you will not add Biocide 1.
Timed Additions: 1 week cycle should be selected if you want Biocide 1 to be added up to twice
per day, in a cycle that will be repeated in the same way every week.
Timed Additions: 2 week cycle should be selected if you want Biocide 1 to be added up to twice

times per day, every day.
Based on Water Meter Makeup Volume should be selected if you want Biocide 1 to be added
for a programmed amount of time after a programmed volume of makeup water has been added to
the system. This option can only be used if a water meter is installed on the makeup water line.
Biocide 1 Pre-Bleed Mode
Click on the radio button that matches how you want to pre-bleed prior to adding Biocide 1.
Not Used means that Biocide 1 will be added immediately when scheduled, and the bleed valve
will not open to drop the conductivity of the system prior to the chemical addition.
