Modine Controls System Quickstart Guide

Indirect Fired Heating/Make-Up Air System Units (Model Series "D", "H", "I", "O")

WARNING
Installing, starting up and servicing heating, ventilation and air conditioning equipment poses
significant hazards and requires specialized knowledge of Modine products and training in
performing those services. Failure to have any service properly performed by, or making any
modification to Modine equipment without the use of qualified service personnel could result in
serious injury to person and property, including death. Therefore, only qualified service personnel
should work on any Modine products. pCOOEM+ Medium Controller

IMPORTANT
These instructions must also be used in conjunction with the Installation and Service Manual (latest
revision of 5-565, 5-594, or 5-572 depending on unit model number) and Controls Manual (latest
revision of 74-510) that originally shipped with the unit, in addition to any other accompanying
pLDPRO and pGD1 User
component supplier literature. Interface Modules

This guide is designed to walk through the basics of establishing unit setpoints and scheduling for an Indirect Fired Heating/Make-Up Air System Unit (Model
Series "D", "H", "I", "O"). These settings are made using the unit mounted pLDPRO user interface module. The module features an integrated keypad and LCD
graphical user interface screen. For cases where remote access is preferred, the optional pGD1 user interface module provides the same functionality as the
pLDPRO on the unit. Refer to the latest revision of literature 74-543 for additional information.
Every unit with a 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.

1 Begin
a. Install unit in accordance with appropriate Modine Installation and Service Manual. Note: Controller will not be powered until unit has appropriate electrical
connections and disconnect switch is in “ON” position.
b. If the pGD1 remote user interface module will be used instead of the unit mounted pLDPRO interface module, follow the instructions in the latest revision of
literature 74-543 for installation, wiring, and setup of the pGD1.
