Operating Procedures
Figure 10. Carel medium c.pCO primary controller
Operating the Microprocessor
The touchscreen interface panel is ready to use when it is
connected to the Ethernet switch and heat pump power is
ON.
Upon initial start-up, the status line will indicate that the
heat pump is OFF. Press On/Off button on the home
screen to enable System On/Off control pop-up screen.
Next, turn heat pump on or off manually or switch over to
BMS control.
Microprocessor Functions
For practical purposes, all essential control information and
operator actions are read and responded to using the
touchscreen interface panel. The touchscreen interface
panel is connected to the primary microprocessor controller
and is the only way to access many primary controller
functions.
NOTICE
Component Damage!
Failure to follow instructions could damage sensitive
electronic components beyond repair.
To prevent arcing or surges of electrical current, do
not use wires or cables to jump components or
bypass the manufacturer's safety systems.
Password Protection
There are three levels of access to the functions displayed
on the interface. The basic level, 'user,' does not require a
password. The higher access levels are the technician
('tech') and administrator ('admin') levels that can only be
accessed by Trane technical personnel. Contact Trane
technical support regarding the possibility of any potential
issues involving the higher-level functions.
Operator Control
A touchscreen interface panel is the primary means for the
operator or maintainer to monitor and modify a host of
functions involving temperatures, pressures, set points,
alarms, operating schedules, elapsed operating hours, etc.

This touchscreen interface panel can be located within
proximity of the primary microprocessor controller. It is
typically located in the primary module.
The touchscreen interface is connected to and
communicates with all module controllers via the Ethernet
switch. It accesses overall heat pump system functions and
settings as well as individual module settings.
In this manual, all functions, procedures, checklists, system
information, and changes in system parameters (set points,
alarms, primary heat pump controls, and so forth) are
written assuming the operator is using the touchscreen
interface panel.
When connected to the Ethernet switch, the touchscreen
interface panel displays current, real-time, information
about the chiller, as well as the status of critical parameters
within each module of the heat pump system.
Touchscreen Interface Panel
The touchscreen interface panel is used to adjust set
points, clear alarms, and perform detailed setup of the
microprocessor controllers.
The touchscreen interface panel displays information on its
touchscreen whenever specific keys and buttons are
pressed by the operator See following figure.
Basic operator tasks are described in the following
sequence of illustrations that comprise a controller tutorial.
Figure 11. Touchscreen interface panel
Touchscreen Interface Tutorial
This section consists of a tutorial that first-time personnel
can use to navigate through the various functions and
features that are available in the interface.
Each of the main screens in the interface contains active
hot spots to activate virtual buttons and switches by simply
touching the screen.
