Using the Maestro Software to
Modify Parameters
Introduction
This section covers how to modify setpoints and other parameters on
the ACT2 controller using the Maestro software interface.
Controller setpoints and other parameters can be modified in several
ways:
•
Remotely, via a modem connection and dialing into a site
•
By connecting a computer directly to the controller with a cable
•
By changing parameter values offline, saving the changes to the
computer hard drive, and later connecting to the controller and
downloading the changes
Parameters setup is grouped into four main categories, with
subcategories as follows:
•
Condensing Unit
