AUX controls programming

AUX controls programming

The Pearl Control system has many standard, built-in equipment types.  They are pre-programmed control equipment types making controlling your greenhouse or grow room operations easy.  All you need to do is to select the appropriate equipment type, and configure it to suit your particular needs.

However, we do realize that there are unique situations where a particular control sequence is needed.  It's important for the users to be able to create the desired control sequence in the field quickly, without any coding expertise.

Link4 has created the AUX Control feature for this particular need.  It is a set of 128 flexible When <a condition is met> then DO <the appropriate action>.

You can create variables (standard and persistent) as well making this a very convenient but powerful feature!


Here is an example.  Note: you can pause (or comment out) a statement as shown in #3 below:
