Controller Overview
Description and Features
The Modine Controls System utilizes a Carel pCOOEM+
programmable microprocessor controller. Highly ad-
vanced with a powerful microprocessor and fast process-
ing speed, the controller features a high number of I/O’s
for complex HVAC/R applications.
The main controller board is housed in a plastic case that
ensures a high index of protection and reduces the risk
of electrostatic discharges due to incorrect handling. The
controller offers greater safety due to the optical isolation
of the serial pLAN, protection of the analog inputs in the
event of incorrect connections, and an extended range of
operating temperatures. Given the increasing demand for
integration, pCOOEM+ can interface with BMS systems
via many of the most commonly-used serial communi-
cation standards, using optional boards. Some of the
features of the Carel pCOOEM+ programmable micropro-
cessor controller are listed below.
pCOOEM+ Main Features:
●12 Universal Inputs
◦Uses 10K NTC temperature sensors
◦4-20mA humidity and CO2 sensors for reliability
●5 Analog Outputs
◦0-10 Vdc for emodulating control
●8 Digital inputs
◦Used to monitor all aspects of the unit
●13 Digital Outputs
◦True relayed outputs for reliability
●Real Time Clock
◦With battery backup and daylight savings adjust-
ment
●pLAN Communication
◦To allow connectivity to space sensors and other
controllers
●Alarm Logging
◦With a snapshot of the unit sensors
●Run Hours Logging
◦With maintenance setpoints
●Password Protection
◦Two levels of password protection
●Manual Control
◦For easy startup and service
●Simple Interface
◦Easy to understand menus and settings
●Built in Scheduler
◦Up to 7 periods per day - Either On/Off control or
Occupied/Unoccupied
◦Holiday scheduler with up to 16 holiday periods
●Remote Display Option
◦Can be 100 ft from unit using standard RJ12 cable
●All reset points fully adjustable
