Operation and Maintenance Manual
Rev: L13
A – 5.8: Autofill
If your controller is set up to control an Autofill
valve, it can be triggered by the Surge Pit Level (if
monitored) or a proximity switch.
Set Point (Op):
Only shown if Autofill sensor type is
set to Surge Pit Level.
This value sets the surge pit
level that the controller will fill to.
Alternate Set Point (Op):
Only shown if Autofill
sensor type is set to Surge Pit Level.
To program when
to use the alternate set point, see the section on
Chlorine (Bromine) Control’s Alternate Set point
Timer Settings. After the schedule is set, you may
choose the alternate set point option and enter the
desired setting.
Start Delay (Op):
Sets the time required for the
water level to stay below the trigger point before
fill begins.
End Delay (Op):
Sets the time required for the
water level to remain above shutoff point before
ending the fill.
Failsafe Timer (Op):
This value sets the time
that the relay is allowed to stay on without
reaching set point before the relay is locked out. If
Autofill has been trying to achieve set point
without success for the selected time, the
controller will cut power to the relay, flash the
Reset Fail/Safe LED on the face panel and display
a message to alert the operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
A – 5.9: TDS Control
If your controller is set up to monitor the TDS of
the water, you will have the following options:
Makeup water TDS (Op):
Enter the test kit
TDS reading for the water controlled by your
Autofill. This is used to determine the appropriate
TDS set point.
Pool TDS cycle (Op):
Enter the pools' cycle
multiplier of the incoming makeup water. The
resulting TDS set point is the incoming makeup
water's TDS times this value.
Failsafe Timer (Op):
This value sets the time
that the relay is allowed to stay on without
reaching set point before the relay is locked out. If
the TDS control has been trying to achieve set
point without success for the selected time, the
controller will cut power to the relay, flash the
Reset Fail/Safe LED on the face panel and display
a message to alert the operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
A – 5.10: Sensor Wash
If your controller is set up to do a Sensor Wash
you will have the following options:
4 Event 28 Day Timer (Op):
Once you have
entered Sensor Wash, select 4Event 28Day Timer
from the menu. The 4 Event 28 Day Timer
allows
you to program the sensor wash on a schedule. See
the section on Super Chlorination's 4 Event 28
Day Timer for details on how to set this.
Start/End Time (Op):
Allows you to set
what times the feed may be triggered during a
day.
# Of Cycles (Op):
Only shown if Duration is not
zero.
Sets how many times the relay will trigger
between the Start and End times.
Duration (Op):
Sets how long the feed will run
for each cycle. If set to zero, there are no cycles
and the relay will simply be on when current time
is between the active event's start and end times.
A – 5.11: Enzyme
If your controller is configured to control an
Enzyme feed, you will have the following options:
Start/End Time (Op):
Allows you to set what
times the feed may be triggered during a day.
# Of Cycles (Op):
Only shown if Duration is not
zero.
Sets how many times the relay will trigger
between the Start and End times.
Duration (Op):
Sets how long the feed will run
for each cycle. If set to zero, there are no cycles
and the relay will simply be on when current time
is between the start and end times.
A – 5.12: UV Turndown
If your controller is configured to control a UV
unit, you will have the following options:
Combined Cl Set Point (Op):
This option is only
shown if both the free Cl and total Cl probes are installed.
This value sets the Combined Cl level that the
input must be equal to or drop below to activate
the turndown.
Start Delay (Op):
This option is only shown if both the
free Cl and total Cl probes are installed.
Time the
combined free Cl must remain at or below set
point before activating turndown.
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 UV turndown relay turns on.
