t DPD Bottle Level: The percentage of DPD reagent left. Press the Up
Arrow to change the value in 10% increments.
TrueDPD Error Screen - Option
If “err” displays on the TrueDPD Information screen, press 1 or 7 to view the
past errors. Viewing the errors clears the error status and any listed errors
that have occurred since the last time viewed.
t — Pool DPD errors
t ClearV below 3.5v: The voltage was low one time, on the second attempt the clear voltage was above
3.5.
t ClearV below 3.5v 2 times, PPM = - - - : On the second attempt to make a measurement the clear
voltage was still below 3.50, the measurement was canceled and the measurement set to - - -.
t ClearV above 4.9v: The voltage was high one time, on the second attempt the clear voltage was below
4.9.
t ClearV above 4.9v 2 times, PPM = - - -: On the second attempt to make a measurement the clear
voltage was still above 4.90, the measurement was canceled and the measurement set to - - -.
t ClearV below DPDv: Warning - Notification that the DPD voltage was above the clear voltage. If there
is no sanitizer or the PDD bottle is empty this can happen and is a warning.
t DPDv was 0: Warning - Notification that after adding the DPD reagent the voltage dropped to 0. This
can happen if the sanitizer is very high. The TrueDPD is accurate from 0 to around 8.0, if the DPDv is 0
the sanitizer is above 8.0 and high.
t DPD Varying #: The TrueDPD requires two consecutive measurements to be close. This warning is the
number of times since the last time the error screen has been viewed that an additional measurement
was made because the DPDv varied over the previous measurement. This can happen if the sanitizer
level changed. If unable to make 2 consecutive close measurements in 6 attempts the PPM will be set
to - - - and the measurement aborted.

TrueDPD Menu
Main Menu - TrueDPD
The TrueDPD is an optional piece of equipment that can be enabled in the
Setup menu.
t Manual Control: Allows for manually controlling all of the functions of the
TrueDPD which is useful to make sure everything is working properly and
purging the DPD.
t P1 / 2: The current pool being measured.
t C##: The current seconds count in the measurement cycle. A full cycle takes about 82 seconds.
t V#.##: The current measured voltage
t Err: Displays if there has been any errors in the measurement, press 1 or 7 to view.
t Purg: After replacing the DPD reagent, select “purg” by pressing 2 to turn the DPD pump on for about
4 seconds which will purge the tubes with fresh reagent.
t Meas: Press 3 to start a measurement cycle.
t Reagent: Liquid/Powder - The TrueDPD supports two different reagents for making the measurement.
The standard powder mix is low cost, accurate but darkens over time at higher temperatures. The
Liquid DPD is Lamotte 1B (P-6741) and lasts up to 90 days in heat. It is available on Amazon and for
this reagent the shelf life date is important. ControlOMatic does not carry this reagent because of the
shelf life. Liquid reagents from other companies will not work with the TrueDPD, only Lamotte 1B.
t DPD Bottle: 4oz, 8oz or 16oz. A 4 oz bottle has enough reagent for about 1800 measurements.
t Cycle: The cycle time between measurements and can be set to 10 min, 20 min, 30 min, 1 hour, 2
hour, 4 hours or 6 hours. Set to 0 to not make a measurement.
