IM 1133-C General Information This manual contains the information you need to install the DIII-NET Communication Gateway on a MicroTech® III Applied Air Handling Unit (AAH) Controller (i.e., RoofPak™ applied rooftop, Maverick™ II commercial rooftop or Self-Contained Unit), incorporate it into the DIII-Net network, and maintain it.
IM 1133-C NOTICE This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with this instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
IM 1133-C Component Data Major components of the DIII-NET Communication Gateway are labeled in . Figure 2, DIII-NET Communication Gateway Installed 24VAC DIII Communication Port LED’s H1P through H7P. DS1 Part Number DS2 Modbus Communication Port Light Emitting Diodes (LEDs) The LED’s on the DIII-NET Communication Gateway are used to indicate either the DIII-NET Communication Gateway is working correctly or there is a fault.
IM 1133-C Installation The DIII-NET Communication Gateway will be factory installed. If it is necessary to replace this board, see section Replacing DIII-NET Communication Gateway. If a new board is being installed on an existing unit, see section Installing a New DIII_NET Communication Gateway. Wiring ! CAUTION Electrostatic discharge hazard. Can cause equipment damage. This equipment contains sensitive electronic components that may be damaged by electrostatic discharge from your hands.
IM 1133-C 5. Install 120/24 VAC transformer in the control cabinet. The DIII-NET Communication Gateway must have its own, power supply. 6. Wire 120VAC power to the transformer using open terminals from the T1 transformer inside the unit control cabinet. The secondary of this transformer must remain ungrounded. Figure 4, DIII-NET Communication Gateway mounted in unit 7. Connect the 24VAC power from the transformer to X6A on the DIII-NET Communication Gateway using the provided wire harness.
IM 1133-C Figure 6, Incorporating DIII-NET board into an existing Modbus Daisy Chain 11. Connect a pair of wires from the MCB to the Modbus Communication Port (X2M) on the DIII-NET Communication Gateway. See Figure 5. (There should be 2 pairs of modbus wires connected to the MCB at this point, unless there were none to begin with, see Figure 6.) 12. The DIII-NET Communications Gateway is treated like any other outdoor unit on the DIII-NET communications trunk.
IM 1133-C 13. Position the binary DIP switches on the DIII-NET Communication Gateway to “0110 1010” as configured in Figure 8. 14. Power up the Daikin Applied Air Handling Unit, MicroTech III Unit Controller and DIII-NET Communication Gateway. 15. Configure MicroTech III and Daikin VRV unit controllers as instructed in the Integration section. For information on the iTouch Manager, refer to user’s manual EM11A017.
IM 1133-C Integration Once the DIII-NET Communication Gateway has been properly installed on the unit and connected to a DIII network, it is then possible to integrate the unit controller with a Daikin Intelligent Touch Controller or iTouch Manager over a DIII network. The integration process is described in the following section.
IM 1133-C DIII-NET Communication Gateway Addressing Before a unit can be viewed and controlled through a DIII network, the DIII-NET Communication Gateway must be assigned a DIII address. Configuring the DIII board is done through the MicroTech III unit controller. The following diagram in Figure 9 details the menu structure of the MicroTech III Applied Air Handling Unit Controller related to the DIII-NET Communication Gateway.

IM 1133-C iTouch Manager Operation This section describes the operation of the iTouch Manager to monitor and control Daikin Applied Air Handler Units. Refer to EM11A017 for more information about the operation of the iTouch Manager, available on www.daikinac.com. If the Intelligent Touch Controller is being used, see section “Intelligent Touch Controller Operation” Turning a Unit On and Off The iTouch Manager allows units to be easily turned on and off directly from the device list screen. 1.
IM 1133-C Adjusting Setpoints Note: This only applies if ‘Std’ or ‘USw/Spt’ is selected for iTouch Version. Refer to DIII-Net Communication Gateway Addressing section for more information. The discharge air temperature setpoint cannot be adjusted with ‘USw/oSpt’ selected. The iTouch Manager adjusts the active setpoint of an AHU. If the unit is in cooling mode, the iTM will adjust the cooling setpoint, if the unit is in heating mode the heating setpoint will be adjusted.
IM 1133-C Figure 51, Adjusting Fan Speed from the iTouch Manager Change Fan Speed Selected Unit Advanced Settings The Detailed Setup screen allows multiple changes to be made to a unit at once. As well as containing standard controls such as On/Off and Setpoints, this screen also has several advanced settings. Main Tab – Unit Settings 1. Access the Indoor Devices list.

IM 1133-C 6. Note: When prompted, confirm unit setup. Changes will be sent to the unit controller. The MicroTech III’s internal setpoint restrictions will always be enforced, regardless of iTouch Manager’s settings. Enabling setpoint restrictions in the iTouch Manager imposes additional restrictions on the range of setpoints that can be sent to the unit controller for more precise management over the space temperatures and energy savings.
IM 1133-C Service Information Test Procedures If you can control the unit from its keypad, but you are not able to communicate with unit via the DIII network, follows these steps: Check the network wiring. Check the network parameters and verify that they are correct, and that there are no duplicate devices on the network. (Addresses must be unique.) See section “DIII Communication Gateway Addressing” Verify that the MicroTech III controller is setup correctly.
