It’s critical to note that this controller isn’t just an ON/OFF switch (i.e. ON when below the set point, OFF when
above [though it can be made to work this way, see Section 3.10]). It’s a predictive controller instead. The controller
anticipates (calculates) the percentage of power to apply to the heater right now to manage the form of the heating
curve minutes in ahead based on the shape (slope) of the heating curve.
The tuning parameters are signicant because they act as constants in the equation that the temperature meter
employs to make its predictions. Poor temperature control will occur if the temperature meter is congured with
tuning parameters that incorrectly characterize the heating mantle being utilized. However, temperature control of
± 0.1o is often attained when the proper parameters are supplied.
Manual Tuning.
Manual tuning is when the values of the 5 tuning parameters are determined manually and then entered into
the temperature controller via the push buttons on the front of the controller. Experienced users might prefer to
manually tune the controller since this allows customization of the heating process.
NOTE: Before your controller leaves the factory, Ecodyst Scientic, Inc. makes sure it is already tuned to t
the specications of the heating mantle you ordered. As a result, your controller doesn’t require any more
adjustment. Contact us for assistance and technical guidance before making any technical modications.
Autotune
For each type of heater, the temperature controller’s Autotune feature automatically determines the tuning settings
(such as delay times, heating eciency, etc.). The tuning parameters are calculated once the autotune process is
nished, and the controller stores them in memory for both present and future usage.
The autotune feature isn’t recommended for heating mantles. Hence the procedure is not included in this manual
but can be provided upon request.
