MiniWarden Manual 530-487-5007 30
TrueDPD: This menu item is not used unless the TrueDPD sensor is installed. TrueDPD is an optional
external sensor to PoolWarden that measures free chlorine using the DPD colorimetric method. Please
refer to the TrueDPD Operation Manual to use this System Menu item.
TrueDPD Cycle: This menu item is not used unless TrueDPD is installed. The is the cycle time
between measurements and can be set to 10, 20, 30 and 60 minutes.
ORP Cal: Press Enter to Enable or Disable ORP Calibration. The default setting is Enabled. If disabled
the ORP will not be able to be calibrated and any changed in sanitizer level require changing the
setpoint.
Display Type: LCD: Press Enter to cycle between VFD and LCD. The default display is the LCD type.
Service Quickjmp: When set to ON, pressing the Left Arrow from the ‘Default Readings Screen” will
jump to the “Service“ menu without requiring a password even if security is enabled. Pressing Back will
return to the “Default Readings Screen” and not the “Main Menu”.
❑ Press 1 to disable the relays, a number will appear in the upper right corner that will count down.
When it reaches 0 the MiniWarden will go back to normal operation. Press 1 again to immediately
set the time to 0 and put MiniWarden back in auto mode.
❑ Press 4 to jump to ORP calibration, or ORP setpoint if ORP calibration is disabled.
❑ Press 5 to jump to pH calibration.
❑ Press 7 to jump to manual relay control.
Factory Defaults: Warning, selecting this will completely restore all settings to the original factory
defaults conditions including relay control types, relay programming and calibrations. When selected, a
Warning screen will display and you must press 9 to proceed or any other button to exit without
resetting everything.
Advanced Relay Types
The relay types supported for pH are Acid and Base. There are 4 selections for ORP: Liquid, Feeder, Cal
Hypo and Salt System. Liquid and Cal Hypo have the exact same relay programming, and Feeder and Salt
System have the exact same relay programming.

SetOvrfeed Same
Feed limit based on the setpoint being achieved
Overfeed Same
Daily feed limit
Proportional and ORP Over Run: For a feeder, proportional control isn’t needed because the relay will
stay on until the setpoint is achieved. ORP Over Run allows for 0, 5, 10 or 15mv to be added to the
setpoint, it will turn on at the setpoint, and o at the setpoint plus this value.
On Time and MinTimeOn: For liquid, the On Time is part of the cycle, it will be on for the programmed On
Time or less and then the MinTimeO will start which allows the added chemicals to mix. For the Feeder,
the MinTime On is the minimum amount of time the relay will be on, even if the setpoint is achieved. Note
that the relay may be on longer than this time if the setpoint isn’t achieved within the programmed time.
