What is the 30MP Multi-chiller application?
The 30MP Multi-chiller is a special purpose application used to control from two to eight 30MP chillers as a single
large chiller, which is operated from the AppController. Each 30MP chiller must be equipped with the 30MP UPC
Open interface. The 30MP Multi-chiller application operates each individual chiller in the most efficient manner by
staging the machines independently. As a system, it reduces the Kw/ton energy consumption at part load
operating conditions. The 30MP Multi-chiller application can run in 100% stand-alone mode or communicate to an
i-Vu® Control System.

1 Mount the controller (page 4).
2 Wire the controller for power (page 5).
3 Set the controller's address (page 5).
4 Wire the controller to the BACnet MS/TP or BACnet ARC156 network (page 6).
5 Wire inputs and outputs (page 7).
6 Wire sensors to the controller (page 12).

Mounting the controller
WARNING
When you handle the controller:
•Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material.
•Do not touch components or leads.
•Handle the board by its edges.
•Isolate from high voltage or electrostatic discharge.
•Ensure that you are properly grounded.
Screw the controller into an enclosed panel using the mounting slots on the coverplate. Leave about 2 in. (5 cm)
on each side of the controller for wiring. Mounting hole dimensions 5 9/16" (14.1 cm) between mounting slot
center lines.

Wiring the controller for power
WARNING
Do not apply line voltage (mains voltage) to the controller's ports and terminals.
CAUTIONS
•The controller 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 Remove power from the power supply.
2 Pull the screw terminal connector from the controller's power terminals labeled
Gnd
and
Hot
.
3 Connect the transformer wires to the screw terminal connector.
NOTE
If using a grounded transformer, connect the ungrounded lead to the
Hot
terminal to avoid damaging
the transformer.
4 Apply power to the power supply.
5 Measure the voltage at the controller’s power input terminals to verify that the voltage is within the operating
range of 21.6–26.4 Vac.
6 Insert the screw terminal connector into the controller's power terminals.
7 Verify that the
Power
LED is on and the
Run
LED is blinking.
Addressing the controller
You must give the controller an address that is unique on the network. You can address the controller before or
after you wire it for power.
1 If the controller has been wired for power, pull the screw terminal connector from the controller power
terminals labeled
Gnd
and
Hot
. The controller reads the address each time you apply power to it.
2 Using the rotary switches, set the controller address. Set the
Tens
(
10's
) switch to the tens digit of the
address, and set the
Ones
(
1's
) switch to the ones digit.

Maximum length: 2000 feet (610 meters)
WARNING
Do not apply line voltage (mains voltage) to the controller's ports and terminals.
To wire the controller to the BACnet network
1 Pull the screw terminal connector from the controller's power terminals labeled
24 Vac
and
Gnd
(
Return
).
2 Check the communications wiring for shorts and grounds.
3 Connect the communications wiring to the controller’s screw terminals labeled

Description
IN-1, IN-2 0–5 Vdc The input impedance of the controller is approximately 30k Ohm.
All Pulse counter Pulse counting up to 10 pulses per second.
Minimum pulse width (on or off time) required for each pulse is 50
msec.
Binary outputs
The controller has 5 binary outputs. You can connect each output to a maximum of 24 Vac/26 Vdc. Each output is
a dry contact rated at 1 A, 24 V maximum and is normally open.
To size output wiring, consider the following:
•Total loop distance from the power supply to the controller, and then to the controlled device
NOTE
Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.
•Acceptable voltage drop in the wire from the controller to the controlled device
•Resistance (Ohms) of the chosen wire gauge
•Maximum current (Amps) the controlled device requires to operate
Analog outputs
The controller has analog outputs that support voltage. The controlled device must share the same ground as the
controller and have the following input impedance:
0–10 Vdc Minimum impedance 2000 Ohms, max 5 mA
NOTE
Ohm's law: -10V/.005a = 2000 Ohms

Wiring sensors to the controller
You can connect the following sensors:
•Leaving chilled water header temperature (required)
•Outdoor air temperature (optional)
•Relative humidity (optional)
NOTE
This document gives instructions for wiring the sensors to the controller. For mounting and wiring the
sensors, see the Carrier Sensors Installation Guide.
WARNING
Disconnect electrical power to the controller before wiring it. Failure to follow this warning could
cause electrical shock, personal injury, or damage to the controller.
CAUTIONS
•Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC or DC service wiring.
•Do not abrade, cut, or nick the outer jacket of the cable.
•Do not pull or draw cable with a force that may harm the physical or electrical properties.
•Avoid splices in any control wiring.

The leaving chilled water header temperature sensor is required and used to measure the temperature of the
water in the common supply header leaving the chillers.
1 Strip the outer jacket from the cable for at least 4 inches (10.2 cm). Strip .25 inch (.6 cm) of insulation from
each wire.
2 Wire the sensor to the controller. See diagram below.
3 Sensor may be terminated at Input 4.
4 Apply power and verify sensor readings.
To wire an outdoor air temperature sensor to the controller
Part #33ZCSENOAT
You can use an optional outdoor air temperature (OAT) sensor to provide a reset of the chilled water setpoint
adjustment based on the OAT reset.
1 Strip the outer jacket from the cable for at least 4 inches (10.2 cm). Strip .25 inch (.6 cm) of insulation from
each wire.
2 Wire the sensor to the controller. See diagram below.
3 Sensor may be terminated at Input 3.

4 Apply power and verify sensor readings.
To wire the Relative Humidity sensor to the controller
Wall and duct sensor - Part #33ZCSENSRH-02
You can use the optional relative humidity (RH) sensor to override the OAT reset in order to provide better humidity
control.
NOTE
The RH override requires that the OATsensor is installed and OAT reset function is enabled and active.
Otherwise, there is only RH sensor monitoring and alarming.
1 Strip the outer jacket from the cable for at least 4 inches (10.2 cm). Strip .25 inch (.6 cm) of insulation from
each wire.

4 Apply power and verify sensor readings.
Wiring an Equipment Touch to the controller
A single Equipment Touch is the only device you can wire to the controller's Rnet port. You can use a 2-conductor
cable instead of the standard 4-conductor Rnet cable and follow the instructions below.
NOTE
The Rnet communicates at a rate of 115 kbps.
For complete Equipment Touch installation instructions including wiring diagrams, see the Equipment Touch
Installation and Setup Guide.
1 Turn off the controller's power.
2 Partially cut, then bend and pull off the outer jacket of the cable. Do not nick the inner insulation.
3 Strip about .25 inch (.6 cm) of the inner insulation from each wire.
4 Wire the controller's
Rnet+
and
Rnet-
terminals to the terminals of the same name on the Equipment Touch's
connector.
NOTE
If using shielded wire, connect the shield wire and the ground wire to the
Gnd
terminal.
