Main Menu - Relays
The PoolWarden Aux relays are covered in the Setup section and Appendix A.
From the Readings Screen press the Back button to access the Main Menu
and select Relays. The relays are controlled with commands that can be
enabled or disabled. Any command that has a value of 0 is disabled. The
values listed are the defaults. When using the Cycle control type, please refer
to appendix B. Only Aux relays that have been setup will display. Scroll to the
appropriate relay and press Enter to edit the settings.
Relay Setup: pH1 and pH2
In the Relay Menu scroll to pH1 or pH2 and press Enter. The following
reviews each command within a pH Relay.
t Manual Time 00:02:00: Is the amount of time you can set a relay to turn
on manually.
t PH Control Span: Select 0.0, 0.2, 0.3 or 0.4. When the measurement is
greater than the span away from the setpoint the on time will be the full on
time. When the measurement is between the setpoint and the span away
from the setpoint the on time will be decreased to reduce overshooting the
setpoint. When set to 0.0 the on time will not be adjusted. Press Enter or
Right Arrow to cycle the values.

pH Relay Settings
t Acid Setpoint 7.5: The relay will turn on if the measured pH reading is greater than 7.5.
t Base Setpoint 0.0: The factory default setting is 0.0 (disabled). When set, the relay will turn on if the
measured pH reading is less than the value. Note: One of the two setpoints must be 0.0.
t On Delay 00:00:20: The turn on delay requires the setpoint condition to be met for an extended period
of time before turning the relay on. The value 00:00:00 disables the on delay.
t Max Time On 00:00:30: When the relay turns on this is the maximum time before it turns off. If the pH
reading is not being maintained then more or less on time may be needed. The maximum time may be
less if the pH control span is used.
t MinTimeOff 00:05:00: This is the minimum amount of time the relay will be OFF after it was on. Allows
for chemical mixing.
t Off If RLY On -none: The default setting is none or disabled. This feature prevents 2 relays being on at
the same time. This is useful in cases where the chemical injection points are very close together and
prevents the pH relay from being on at the same time the ORP relay is on. Simply press Enter to toggle.
t Off if Flow Off - 1 or 3: The pH Relay will be turned off if “No Flow” is detected in Flow Switch Input 1
for Pool1 and if “No Flow” is detected in Flow Switch Input 3 for Pool2. Note: This setting can’t be
changed as it relates to safety, pressing the Right Arrow to change has no effect.
t SetOvrfeed 00:00:00: Setpoint overfeed requires the measurement to reach the setpoint to clear. If a
feed tube is broken and the chemicals are going on the floor this type of overfeed protection will detect
that and shut down the relay sooner than the daily overfeed. Calculate how much feed time is required
for the setpoint to be reached when the pH is a full point off. When the Setpoint Overfeed is reached the
relay status will display an “s”. The default value is 00:00:00 which is disabled, in order to use this feature
calculate the amount of time required and enter that time.
qSetpoint Overfeed can be cleared by manually fixing the chemical imbalance or clearing the overfeed
timers in the Service menu.
t Overfeed 01:00:00: The Overfeed time represents the maximum amount of time a relay can be on from
midnight to midnight. This must be set up properly to reduce the chance of feeding large amounts of
chemicals in the event something goes wrong and the default time will most likely need to be adjusted.
