pGD1 Display Module

pCOOEM+ Controller

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.

Begin
a. Install unit in desired location in accordance with appropriate Modine Installation and Maintenance Manual. Note: Controller will not be powered until unit has appropriate electrical connections and disconnect switch in “ON” position.
b. If display module is not unit mounted, connect pGD1 handheld module using RJ-12 communication cable provided in port J15 as shown on unit mounted wiring diagram.
