Touchscreen devices
You can connect the TruVu™ ET Display to the TV-OPT's Ethernet Service port to view or change the controller's
driver properties. You can also create a custom Touch file to provide a graphic representation of the controlled
equipment or to provide access to schedules, view trends and alarms, and more without having to access the
system's server.
NOTES
•These touchscreen devices are not powered by the Ethernet port.
•The TruVu™ ET Display requires a 24 Vdc external power source.
CAUTION A touchscreen device can share a power supply with the Carrier controller if:
•The power source shared by the controller and Equipment Touch is AC power.
•The power source shared by the controller and TruVu™ ET Display is DC power.
•You maintain the same polarity.
•You use the power source only for Carrier controllers.
Chiller system configurations
The program is scalable, so it can be applied from a minimal system including only the chiller and chilled water
pump components, to a larger system, including condenser water side components and air handling unit fans, as
illustrated below.
Even though the controller works with a variety of chilled water system components, it must be used with parallel
chiller systems and operates best with variable speed pumps and variable speed fans.

What is the TV-OPT?

The TruVu™ Chilled Water System Optimizer works with systems containing any of the following:
•Single chiller or multiple chillers piped in parallel
•Chilled water pumps
•Cooling towers
•Condenser water pumps
•Variable speed air handling unit fans (w/ chilled water coils)
•Chilled water side –when secondary pumps and tertiary pumps are part of the chilled water system,
including variable air handling unit fans.
•Condenser water side –systems with multiple cooling towers and condenser water pumps dedicated to their
corresponding chiller, or piped in parallel.
CAUTIONS
•The control program can be less effective if the setpoint response is not predictable. For example, when the
cooling towers are widely staged to come on above certain temperature thresholds, rather than using
modulating VFD fans or pumps for capacity control.
•The TruVu™ Chilled Water System Optimizer is not designed for series arrangements or absorption chillers.
The TruVu™ Chilled Water System Optimizer can be applied to the following chiller system designs:
•Chilled water supply side
○Up to 8 chillers piped in parallel arrangement
▪Centrifugal, scroll type, or screw type chillers
▪Equal-sized or unequal-sized
○Up to 40 primary, secondary, and/or tertiary variable speed pumps
○Up to 40 variable speed air handling unit fans serviced by chilled water system
•Condenser water supply side
○Up to 20 condenser water pumps
○Up to 20 cooling tower variable speed or staged fans

Installation overview
WARNING This controller only supports a single Chilled Water System Optimizer program and no other
control programs.
The TruVu™ Chilled Water System Optimizer collects remote power (kW) values and facility thermal load values
residing in other controllers through Network Input points.
The program functions most efficiently and provides increased energy savings if all pumps and fans have variable
frequency drives and as more power inputs are measured, however constant volume/constant flow systems are
supported.
Control Inputs
•Power Inputs —Sum of power inputs Σ kW
○Chiller power kW (required)
○Chilled Water Pump kW (required)
○Cooling Tower Fan kW (optional, but beneficial)
○Condenser Water Pump kW (optional, but beneficial)
○Air Handling Unit Fan kW (optional, but beneficial)
•Load Input —Total Cooling Load
NOTE This is thermal cooling load in tons, whether calculated from the difference between chilled water
supply and return temperatures and the flow rate, or tonnage if it can be read directly.
•Result —kW/Ton (Dividing total kW by the thermal load equals the efficiency benchmark of kW/ton)
Control Outputs –Network Outputs
The optimization program has only two control outputs. They are either Network Outputs or BACnet Analog Values.
•Chilled water supply temperature setpoint
•Condenser water supply temperature setpoint
Safety considerations
WARNING Disconnect electrical power to the TV-OPT before wiring it. Failure to follow this warning could
cause electrical shock, personal injury, or damage to the controller.

WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.
CAUTIONS
•The TV-OPT is powered by a Class 2 power source. Take appropriate isolation measures when mounting it in a
control panel where non-Class 2 circuits are present.
•Carrier controllers can share a power supply as long as you:
•Maintain the same polarity.
•Use the power supply only for Carrier controllers.
To wire for power
1 Make sure the TV-OPT’s power switch is in the OFF position to prevent it from powering up before you can
verify the correct voltage.
2 Remove power from the power supply.
3 Pull the red screw terminal connector from the controller's power terminals labeled 24 Vac/Vdc (+/-).
4 Connect the power supply's wires to the red screw terminal connector.
5 Connect an 18 AWG or larger wire from the power supply's negative (-) terminal to earth ground. This wire
must not exceed 12 in. (30.5 cm).
6 Apply power to the power supply.
7 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating
range of 20 to 30 Vac or 23.4 to 30 Vdc.
8 Insert the red screw terminal connector into the controller's power terminals.
9 To verify the polarity of the wiring, measure the voltage from the negative terminal of the red screw terminal
connector to a nearby ground. The reading should be 0V.
10 Turn on the expander's power switch.
11 Verify that the LED on top of the controller is on.
12 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating
range of 20 to 30 Vac or 23.4 to 30 Vdc.

Rotary switch settings
Rotary switch settings (see example below) are used to determine the following items in your system, so you
should plan carefully before setting the switches.
•If you use a Default IP address, the final octet is the number created by the three rotary switch settings (must
be a unique number from 1 to 253). See To set the IP address (page 14).
•If you autogenerate the following:
Device Instance, the number is automatically set to a number equal to the ((IP network number x 100) +
rotary switch settings).
BACnet Network Number for Port S1, the number is automatically set to a number equal to the ((IP network
number + rotary switch settings) x 10).
Autogenerating is set up through the controller setup pages (page 35).
•The rotary switch settings determine the router number in the i-Vu® interface.
EXAMPLE The switches below are set to 125.
CAUTION Do not leave the rotary switches set at 0 (the factory default). The TV-OPT cannot be discovered if
the rotary switches are left at 0.

To set up autobaud
The TV-OPT can automatically receive or establish the baud rate on a serial network. When you configure a device
on the network for autobaud and then power it up, the device detects the incoming baud rate on the network and
sets its baud to match.
Autobaud does not work unless there is a device on the network, whether Carrier or third party, that has the baud
rate already set. You can manually set the baud rate on more than one device, as long as the rate is the same for
every device.
NOTES
•The received baud rate stays intact during power cycles.
•We recommend you set the baud rate manually on the router for the network.
MS/TP
MSTP Autobaud can be configured in either the:
•Service Port controller setup pages > BACnet tab > Port S1 or Port S2
or
•The i-Vu® interface, right-click your TV-OPT on the navigation tree, and select Driver Properties > BACnet
Router Properties > MS/TP Configuration on Port S1 or on Port S2. See BACnet Router Properties (page 30).
Modbus
Modbus Serial Autobaud can be configured in either the:
•Service Port controller setup pages > Modbus tab > Modbus RS-485 > Port Configuration
or
•The i-Vu® interface, right-click your TV-OPT on the navigation tree, and select to Driver Properties >
Communication Status > Modbus Serial
NOTE See the Modbus Integration Guide.
NOTE If you set Autobaud or make other changes in the controller setup pages, you must upload the changes to
the system database the first time you access the controller in the i-Vu® interface. This preserves those settings
when you download memory or parameters to the controller.

To set the IP address
You must define the TV-OPT's IP addressing (IP address, subnet mask, and default gateway) in the Service Port
controller setup pages so that the controller can communicate with the i-Vu Server on the IP network.
Use one of the IP addressing schemes described below with the associated instructions that follow.
Use a...
If...
DHCP IP Address
generated by a DHCP server
The IP network uses a DHCP server for IP addressing
Custom Static IP Address
from your network administrator
You do not use a DHCP server and the answer to any of the
following questions is yes. Will the i-Vu® system:
•Share a facility's existing IP data network?
•Have 254 or more devices with static IP addresses?
•Be connected to the Internet?
•Have at least one device located on the other side of an IP
router?
•Have any third-party IP devices?
Default IP Address
that your system creates
The answer to all of the above questions is no.
NOTE Carefully plan your addressing scheme to avoid duplicating addresses. If third-party devices are integrated
into the system, make sure your addresses do not conflict with their addresses.
To set a DHCP IP address
1 On the controller setup Modstat tab, find the controller’s Ethernet MAC address and write it down.
2 On the Ports tab under IP Port, select DHCP.
3 Click Save.
4 Write down the IP Address.
5 Give the DHCP network administrator the IP address and Ethernet MAC address and ask him to reserve that
IP address for the controller so that it always receives the same IP address from the DHCP server.
To set a custom IP address
1 Obtain the IP address, subnet mask, and default gateway address for the controller from the facility network
administrator.
2 On the controller setup Ports tab under IP Port, select Custom Static.
3 Enter the IP Address, Subnet Mask, and Default Gateway addresses that the network administrator gave
you.
4 Click Save.

15
To set a default IP address
Default IP addressing assigns the following to the controller:
•IP address = 192.168.168.x
where x is the setting on the rotary switches in the range from 1 to 253
•Subnet Mask = 255.255.255.0
•Default Gateway = 192.168.168.254
1 Set the controller's three rotary switches to a unique address on the network. Set the left rotary switch to the
hundreds digit, the middle switch to the tens digit, and the right switch to the ones digit.
EXAMPLE The switches below are set to 125.
2 On the controller setup Ports tab under IP Port, select Default IP Address.
3 Click Save.
CAUTIONS
•The Default IP address range is 1 to 253. Setting the rotary switches to 0 will set the Default IP address to 1.
Setting the switches to 255 will set the Default IP to 253. Do not set the switches to 254.
•If you set the Default IP address on the controller setup Ports tab and then change the rotary switches, you
must do one of the following to correct the IP address in the controller:
