This guide is designed to walk through the basics of establishing unit setpoints and scheduling for a
Varsity/Valedictorian unit using the pGD-t display module. Every unit with Modine Controls System is
designed for either standalone or networked operation. For units communicating on a BMS, the guide
will explain how to adjust your unit’s device instance to allow proper communication.
The pGD-t display module can be unit mounted, or handheld depending on the customized order. The
pGD-t allows for complete visibility over the unit’s controls parameters. It is recommended that at least
one handheld device be available at the install site if the need arises to change these settings.
