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.
CEA and CGA models are equipped with ICE’s proprietary Printed Circuit Board (PCB), which 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.
