ORP Relay:
In the Relay Setup Menu scroll down to the ORP relay and press enter.
The following reviews each command within an ORP Relay selection that is
setup as Liquid Chlorine (the control type can be changed in the Relay
Control Types Menu) . The other less common control types such as Cal
Hypo, Salt Systems, etc follow a very similar relay programming and
command structure as Liquid Chlorine. Please use the following as a guide
for those less common control types.
 Manual Time 00:02:00: Is the amount of time you can set a relay to turn
on manually (Default Setting 2 Minutes). To turn the relay on manually
you have to do so in the service menu which will be covered in the next
section. When you turn on the relay manually in the service menu, the
relay will be on for 2 minutes in this case. To change the time, simply
enter the new time and press Enter to save.

 Proportional 10%: The Proportional %-Age
(Default Setting 10%) means that as the
measured ORP reading gets to within 10% (630
in this case) of the ORP setpoint (700 in this
case), the amount of relay on-time will
proportionally decrease as the reading gets
closer and closer to the setpoint. Proportional
feed helps to prevent chemical overshoot. To
change the %-Age, simply press Enter, change
the value and press Enter to save. To disable, set the %-Age to zero “0” and press Enter to save.
 On If ORP < 700: This is the ORP setpoint and the factory default setting is 700. The relay will
turn the chemical feed pump on if the measured ORP reading is less than 700. The relay will turn on
for the programmed on time, in this case for 1 minute as set in the “On Time 00:01:00” command or
less than 1 minute if the measured reading is within the proportional feed %-age of 10%.
 O If pH > 0.00: This is the pH Lockout Command. The default setting is zero “0” or disabled. ORP is
highly dependant on pH. In other words, a high pH reduces the killing eectiveness of the sanitizer and
has a direct eect on lowering the ORP reading even though there is already an ample amount of
sanitizer in the pool. The pH Lockout feature helps to prevent chlorine overfeed. A typical pH Lockout
setting is 8.0 and will lockout the ORP relay when pH reaches 8.0 or higher. The default setting is 0.0 or
disabled.
 On Delay 00:00:20: The on delay, in this case 20 seconds, is necessary to prevent the relay and
hence the chemical feed pump from turning on and o frequently if the sensor measurement uctuates
back and forth from 699 and 700. It means that the relay will not turn on unless the condition of “On If
ORP < 700” is satised for at least 20 seconds - then the relay will turn on for the programmed “On
Time 00:01:00” in this case 1 minute. To change the on delay time, simply press Enter and change the
time and press Enter again to save the new setting. Enter 00:00:00 to disable.
 On Time 00:01:00: This is the total amount of time the relay will be ON if the “On If ORP < 700”
condition has been satised. The default setting is 1 minute. This command works in conjunction with
the MinTimeO Command below. If the ORP reading is not being maintained then more or less on time
may be needed.
 MinTimeO 00:07:00: This is the total amount the relay will be OFF if the “On if ORP < 700” condition
has been satised. This is the amount of time allowed for chemical mixing in the pool and works in
conjunction with the “On Time” Command above. Do not set to 00:00:00 if the On Time is not also set
to 00:00:00 as they work together.
