GENERAL

The standard Carrier Controller software provided on all 30RC/ 30MP chillers and 38RC condensing units are programmed to accept various options to modify the unit operation. The Energy Management Module (EMM) board is required for 4 to 20 mA, 2 or 3-step demand limit control, chilled water temperature reset by space temperature, Ice Mode, LWT (leaving water temperature) for Primary/Secondary chiller control, and Ventilation fan output (30MP only). Chilled water temperature reset by return water or cooler (delta T does not require the addition of this accessory). See Table 1 for EMM functions. The following functions are available with the EMM board:

Chilled Water Temperature Reset — Resets the chilled water set point under less than full load capacity conditions by the following method:
- Space Temperature: A field-supplied space temperature sensor is required.
Demand Limit — Limits the capacity of the machine from unit capacity by the following methods:
- 4 to 20 mA Input: A field-supplied signal generator is required.
- 2 or 3-Step Switch Control: A field-supplied dry contact switch is required.
Ice Done Control Switch — Signals the machine to exit the Ice Build mode and enter an unoccupied time period. A field-supplied dry contact switch is required.
Dual Chiller LWT — Sensor input to allow for control of two chillers by the primary/secondary chiller logic.
Cooling Setpoint — 4-20 mA input for controlling LWT setpoint.
Ventilation Fan Output — Activates ventilation fan for indoor units (30MP units only).

The EMM board can be configured with the Carrier Controller module. See “EMM Board Wiring” on page 3. for detailed configurations.

WARNING

Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation and service. There may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work is completed.

INSTALLATION

Disconnect unit power. Follow proper lockout/tag-out procedures.
Locate the control panel enclosure. See Fig. 1-3 for control \panel layout and location for installation of CIOB/EMM board. See Fig. 4 for address configuration. Dual circuit units have two CIOB/EMM boards. The B circuit CIOB board serves the EMM functions.
NOTE: Dual circuit units do not require an additional board. For these units skip Steps 3 and 4, and continue to Step 5.
Install CIOB/EMM board in the location shown using the screws included in the accessory package. The board will be mounted on top of the existing CIOB/EMM board. The board may be left loose during wiring for easier access to connections while attaching harness plugs. Install TB6 in the location shown in Fig. 1 or 2 as applicable using the screws included in the accessory package. For 30RC and 38RC units, TB6 should have harness already attached as shown in Table 3. Correct connections should be verified. Use harnesses provided in kit to make connections below. See Tables 2 and 3, and the markings on the harness for correct termination.
- a. 30RC and 38RC Units:
  Use a harness connected to TB6 to make connections from CIOB-B to TB6. Follow markings on the harness to connect plugs to CIOB. Use a three-wire harness to make LEN communication connection between CIOB-A and CIOB-B.
- NOTE: This is only required for single-circuit units. Find CIOB-B J15 in main chiller harness and connect to CIOB-B for 24-v power.
- NOTE: This is only required for single-circuit units.
- b. 30MP Units:
  Use harness to make connections from CIOB-B to TB6. Follow the markings on harness to connect plugs to CIOB. Use a three-wire harness to make LEN communication connection between CIOB-A and CIOB-B.
- NOTE: This is only required for single-circuit units. Find CIOB-B J15 in main chiller harness and connect to CIOB-B for 24-v power.

Configuration (All Unit Sizes)

The controls must be configured to recognize the EMM accessory. The Carrier Controller display may be used to do this. See the Energy Management Module (EMM) section in the Controls, Start-Up, Operation, Service and Troubleshooting guide for con- figuration information. The Carrier Controller must be set up to communicate with the EMM module (Main Menu Configura- tion → Menu – Factory Parameters/Enable Option → 13A or 4A = Yes).

Temperature Reset

CAUTION

Care should be taken when interfacing with other control systems due to possible power supply differences such as a full wave bridge versus a half wave rectification. Connection of control devices with different power supplies may result in permanent damage. Carrier Controller controls incorporate power supplies with half wave rectification. A signal isolation device should be utilized if the signal generator incorporates a full wave bridge rectifier.

SPACE TEMPERATURE

A field-supplied 10K thermistor can be used to provide leaving fluid temperature reset. The thermistor must be connected to TB6-12,13. See Fig. 5 or 6. See the Controls, Start-Up, Opera- tion, Service and Troubleshooting guide for configuration infor- mation.
NOTE: If CIOB-B was added, set the board address using the DIP switches per Fig 4.

Demand Limit

4 TO 20 mA SIGNAL A field-supplied and generated, externally powered 4 to 20 mA signal can be used to provide a demand limit signal for chiller ca- pacity reduction. The signal must be connected to TB6-10, 11 (positive, negative). See Fig. 5 or 6. See the Controls, Start-Up, Operation, Service and Troubleshooting guide for configuration information.

CAUTION

Care should be taken when interfacing with other control\ systems due to possible power supply differences such as a full \wave bridge versus a half wave rectification. Connection of control devices with different power supplies may result in \permanent damage. The Carrier Controller controls incorporate power supplies with half wave rectification. A signal isolation device should be utilized if the signal generator incorporates a full wave bridge rectifier.

SWITCH CONTROLLED

A field-supplied set of dry contacts can be used to provide up to three steps of chiller capacity reduction. The three steps are achieved through two sets of dry contacts. The contacts for demand limit switch l must be connected to TB6-5,7 and are on the standard unit. The contacts for demand limit switch 2 must be connected to TB6-3,4. See Fig. 5. The position of these contacts will allow for up to three steps of demand limit according to the following:

CONTACT

| AMOUNT OF CAPACITY REDUCTION
---|---
None| Switch Limit Setpoint 1| Switch Limit Setpoint 2| Switch Limit Setpoint 3
Switch 1| Open| Close| Open| Close
Switch 2| Open| Open| Close| Close

NOTE: Refer to the Controls, Start-Up, Operation, Service and Troubleshooting guide for configuration information.

Ice Mode

A field-supplied set of dry contacts can be used to provide an ice done switch (TB6-1,2) to the controls. See Fig. 5. With ice mode configuration enabled and ice done switch contact open, a brine chiller will be able to operate as desired during off peak times in conjunction with an ice storage system. Operation in ice mode ends when the contact closes. Refer to the Controls, Start-Up, Operation, Service and Troubleshooting guide supplied with the chiller for more information on the correct configuration of this option.

Dual Chiller Leaving Water Temperature (LWT)

For two chillers configured for primary secondary operation in parallel, this input allows for measurement of a mixed water temperature from both chillers. A 5k thermistor is connected across TB6-14 and 15. See Controls, Start-Up, Service, and Troubleshooting guide supplied with chiller for more information on configuring primary/secondary chillers.

Cooling Setpoint (4 to 20 mA)

A field-supplied and generated, externally powered 4 to 20 mA signal can be used to provide the LWT setpoint to the chiller. See the Controls, Start-Up, Service, and Troubleshooting guide supplied with chiller for details on the configuration for LWT setpoint control.

Ventilation Output

On 30MP chillers this output will close when the ventilation interlock input is open for 5 seconds or when a refrigerant leak detector senses a leak over the specified rate. Output is to start ventilation fans to evacuate the indoor space of any leaked refrigerant
