Operation and Maintenance Manual Rev: C17
This screen allows you to set the time to trigger
the event on the programmed weeks/days. The
event will trigger at the start time if the
controller is running at that time. To toggle
AM/PM, press the +/- key. Enter the desired
time and press enter.
After setting the time, press the left arrow to
return to Super Chlorination's main menu. Here
you will notice the next scheduled super
chlorination is displayed for you. The controller
will also list the last super chlorination here once
one has been completed.
 Maximum Time On (Op): This value sets the
maximum time you want the Super Chlorination
on to reach the set point. If the time expires
before set point is reached, the controller will
trigger the SuperChlor failsafe alarm and end the
SuperChlor feeds. (the range is from 0:00 to
18:00 hours)
An operator can reset the failsafe through the
Reset Fail/Safe button; however the failsafe
alarm will automatically clear itself when the
regular Cl feed begins feeding.
 ORP Set Point (Op): This option is only shown if the
Control Input is set to ORP. This value sets the
desired ORP level to shock the pool.
 ppm Set Point (Op): This option is only shown if the
Control Input is set to ppm. This value sets the
desired ppm level to shock the pool.
A – 5.5: Dechlorination
If your controller is configured for Dechlorination,
you will have the following options:
 Control Input (Op): This option is only available if
the ppm probe is installed. Choose between ppm and
ORP to use to control the dechlor feed.
 Follow Super Chlorination (Op): Choose
whether or not you want your dechlorination to
automatically follow your super chlorination.
 4 Event 28 Day Timer (Op): The 4 Event 28
Day Timer allows you to program the
dechlorination on a schedule. See the section on
Super Chlorination's 4 Event 28 Day Timer for
details on how to set this.
 Maximum Time On (Op): This value sets the
maximum time you want the dechlorination on to
reach the set point. (the range is from 0:00 to
18:00 hours)
 ORP Set Point (Op): This option is only shown if the
Control Input is set to ORP. This value sets the
desired final ORP level.
 ppm Set Point (Op): This option is only shown if the
Control Input is set to ppm. This value sets the desired
final ppm level.
A – 5.6: Ozone Control
If your controller is configured for Ozone Control,
you will have the following options:
 Control Input (Op): This option is only available if
the ppm probe is installed. Choose between ppm,
ORP, or both to use to control the Ozone feed.
 ORP Set Point (Op): This option is only shown if the
Control Input is ORP or Both. This value sets the
ORP level that the input must drop below to
activate the Ozone.
 ppm Set Point (Op): This option is only shown if the
Control Input is ppm or Both. This value sets the ppm
level that the input must drop below to activate
the Ozone.
 ORP Hysteresis (Op): This option is only shown if
the Control Input is ORP or Both. This value sets the
level that the input must rise above the set point
before the Ozone control will turn off the relay.
 ppm Hysteresis (Op): This option is only shown if
the Control Input is ppm or Both. This value sets the
level that the input must rise above the set point
before the Ozone control will turn off the relay.
 Fireman Switch (Op): This option is only shown if a
relay is assigned to the recirculation pump or backwash.
This value sets the minimum amount of time to
leave the recirculation pump on or delay the start
of backwash after the Ozone relay shuts off.
 Failsafe Timer (Op): This value sets the time
that the relay is allowed to stay continuously on.
