MiniWarden/PoolWarden + (PLUS) Operation Manual • www.poolwardentraining.com • 23
The two auxiliary relays per pool can be used to control Heaters, Circulation
Pumps, Water Levelers, Back Up Sanitizers, etc. Please note that both
Auxiliary Relays can also manage the same standard pH and ORP control
types that the main pH and ORP relays can manage. The type of control is
selected in the setup menu.
Many of the values in these control types are 0 and if the “Hide Unused
Relay Commands” is active most of the commands will not be visible.
Make sure to change to “Show Unused Relay Commands” the first time
setting up a new type.
t Not Used: This relay isn’t used
t pH: The same acid/base setup as the pH relays
t Sanitizer: Same as the ORP relays
t Heater: Use to control a heater, temperature control
t SuperChlor: Setup an aux relay for super chlorination
t Water Level: Control a solenoid to keep the pool at the proper level
t Chiller: Temperature control, but keeping the water cooler
t Feed daily: Very flexible and can be used to control the main circulation
pump
Heater & Chiller Control Type
t Manual Time 00:02:00: Is the amount of time you can set a relay to
turn on manually.
t Heater Setpoint: This is the Main Temperature setpoint and the factory
default setting is zero “0” or disabled. The relay will turn the Heater on if
the Temperature falls below the set point and will turn off once the set
point is achieved.
t Chiller Setpoint: This is the Main Temperature setpoint and the factory
default setting is zero “0” or disabled. For a chiller the relay will turn on
when the temperature is higher than the setpoint to cool the water down.

Heater Control
t On Delay 00:01:00: The on delay helps to prevent the relay and hence the heater from turning on
and off frequently if the temperature fluctuates back and forth from from the set-point. The relay will
not turn on unless the setpoint condition is satisfied for at least 1:00 Minute.
t MinTimeOn 00:02:00: This is the minimum amount of time the relay will be ON if the Temperature
drops below the setpoint.
t MinTimeOff 00:02:00: This is the minimum amount of time the relay will be OFF after it has been
on.
t Off if Flow Off - 1: Do not turn the heater on if there is no flow in the selected flow sensor.
t Overfeed 05:00:00: The Overfeed time represents the maximum amount of time a Heater can be on
in a 24-Hour period from midnight to midnight. Calculate the maximum amount of total time the
heater would be on in a 24-Hour period and enter the time here.
