Modine Manufacturing pGD1 Quick Start Manual

Modine Controls System Quickstart Guide
Airedale ClassMate (CMD/CMP/CMS) and SchoolMate
®
This guide is designed to walk through the basics of establishing unit setpoints and
scheduling for a ClassMate or SchoolMate unit using the pGD1 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 also explain how to adjust your unit's device
instance to allow proper communication.
The pGD1 display module can be unit mounted, or handheld depending on the customized
order. The pGD1 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.
Please reference AIR74-525 Modine Controls System Manual for more in-depth information.
