a. Configuration
Configuration menu allows the user to change the setup code for the unit, enable
Scheduling, Holidays, expansion I/O and change Field Card settings. Users are
welcomed to enable Scheduling and Holidays. However, code changes and
expansion I/O enabling are to be done under factory advice only!

This code is set from the factory to operate the components selected with
the unit. When troubleshooting, refer to the wiring diagram sent with the unit
(located on the control center door) to verify the Unit Code is correct. The code
will be listed on the wiring diagram.

Unit I/O expansion requires the installation of a pCOe and Field Card. Please
contact the factory for more information.
Enabling the I/O expansion allows the user to add the following points for
monitoring:
• Four analog inputs (0/1vdc, 0/5vdc, 0/20mA, 4/20mA, NTC Temp)
• One analog output (0/10vdc)
• Four digital inputs
• Four digital outputs
The additional I/O points available on the pCOe expansion module allow the
user to monitor and control the additional points over the BMS and user display.

p

address
.
A pLAN (pCO Local Area Network) is a Carel proprietary local area network,
allowing the user to connect multiple controllers to one remote display panel.
Each controller on a pLAN must have a unique address.
This address is only applicable for units connected on a pLAN. For BACnet,
LonWorks or Modbus parameters, go to Service > BMS Config.
T

field card m

seTTings
.
The FIELD CARD is used for peripheral device control (pCOe Expansion
Module).
The Modbus settings should only be changed with factory guidance.
The I/O Configuration menu allows adjustment of all controller inputs and outputs.
This menu is similar to the Probe Adjustment menu, except that it additionally
allows adjustment of the factory default ‘normal’ states of the digital inputs and the
direction of the analog outputs. Additionally, it allows adjustment of the physical
location of each I/O. ADJUSTMENT OF I/O PHYSICAL LOCATION MUST ONLY BE
DONE UNDER FACTORY GUIDANCE! IMPROPER ADJUSTMENT MAY RESULT IN
SYSTEM DAMAGE!
This is an example of an analog input configuration screen.
In the I/O configuration screens, the user can alter the physical location and
type of each point.
Similar configuration screens appear for the remaining I/O.
