2.1 Introduction
WARNING
Failure to observe the instructions contained in this document may result in personal
injury and/or property damage and may void the warranty. Read this manual before
installing, replacing or using this product.
ICE’s proprietary Printed Circuit Board (PCB) sets the standard for the industry in flexibility, reliability
and performance. This UL certified component is engineered to optimize Heating, Cooling and
Dehumidification operation while communicating valuable information to the end user. Special features
include 2-Stage operation with varying speed control to optimize latent and sensible capacity, built in
remote communication (MODBUS) for monitoring and/or control, optimized head pressure control
and the ability to function autonomously without the need for an off the shelf thermostat. The ICE PCB
comes equipped with LEDs to monitor lockouts for independent circuits, which drastically reduces
troubleshooting time and system downtime. Lockout contacts are also provided along with the alarms
being transferred via MODBUS.
This chapter provides the necessary information for installing and operating the ICE PCB.
The diagram below identifies the inputs, outputs and connections for the ICE PCB.
