User Guide v 1.0 — February 2020 Making Adjustments
7.6.13 Change the Output Power Limit Setting
The Output Power Limit lets users set the maximum amount of power that can be supplied
to the heaters. The default power limit for all zones is 100%.
To change the Output Power Limit for a zone, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Advanced Settings drop-down tab.
3. Touch the Output Power Limit field.
4. Type a value from 0% to 100% in the Output Power Limit dialog window.
5. Touch the Accept button.
7.6.14 Change the Zone Control from ART to PID
The Altanium can automatically adjust the control algorithm to work with different heater
requirements. This control method is Active Reasoning Technology (ART). In some condition,
it may be necessary to switch from the automatically adjusted ART algorithm to an algorithm
that can be manually adjusted. This control method is Proportional/Integral/Derivative (PID).
When you change a zone from ART control to PID control, then you can manually enter
values for the Proportional, Integral, and Derivative parameters. The default control mode for
all zones is ART.
To change the zone control between ART and PID, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Control Settings drop-down tab.
3. Touch the Control Mode field.
4. Select ART or PID in the Control Mode dialog window.
7.6.14.1 Change P, I or D Parameter Values
If ART has been used on a zone more then one time and could not get the required control,
change the zone to PID control and adjust the three PID parameters to get the required
control.
To change the PID settings, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Control Settings drop-down tab.
IMPORTANT!
The zone can be changed back to ART without the loss information. The default settings for
all zones are:
• P = 15
• I = 10
• D = 2
