Fan Coil Unit Controller and I/O Expansion Module
The following section describes issues and the corresponding troubleshooting steps for the fan coil unit controller with or without an I/O expansion module. Refer to OM
1111, available on www.daikinapplied.com
, for complete details about LED activity, faults, and additional troubleshooting topics.
Q: Room Sensor LED does not come on, or comes on for a little while, then goes out
A: This could be caused by bad power to the unit controller, incorrect wiring from the unit controller to the room sensor LED, possibly defective hardware, or the unit is configured to operate in the service test mode.
• Verify that the unit controller has 24 VAC
• Verify that the unit is not operating in the service test mode
• Verify if the unit runs/communicates when the LED is off
• If it runs properly without the LED, check the LED wiring connection
• Download application code to the unit controller
• Replace hardware, if necessary
Q: Unit has a room sensor and is constantly in cooling mode or the space temperature constantly reads higher than actual room temperature
While the unit controller has separate connections for both return air and room temperature sensors, it is not possible for both to be used at the same time. Having both sensors connected will cause the room temperature to read higher than the actual temperature.
A: Disconnect the return air sensor.
BACnet & LonWorks Communication Modules
The following section describes issues and the corresponding troubleshooting steps that apply to the BACnet or L

A: The communication module may not be installed properly, the hardware may be faulty, or the LED itself may be faulty.
• Remove the communication module and then re-install it, making sure the connector snaps into place on all four of the pins. Use caution as it is easy to either miss just one pin or all of the pins, even with the standoffs.
• Verify if the BAS recognizes the Neuron ID even if the LED is not lit.
• If the communication module is properly installed but no Neuron ID is broadcast, remove the communication module and install it on a different unit.
If the LED does not function correctly and/or the BAS still does not recognize the Neuron ID, replace the communication module.
Q: The BAS does not “see” some or all L

ORKS
Configuration Properties
A: The communication module uses multiple User-defined Configuration Property
Types (UCPTs) to pass MicroTech III-specific unit information to the BAS. If the BAS can access other L
ON
W
ORKS
variables, then it is likely that the BAS is not allowing access to these user-defined configuration properties.
• The controls integrator should contact his/her technical support to determine how to allow the BAS to access configuration properties.
• The complete set of L

files required for BAS integration are available on www.daikinapplied.com

Flasher
The following section summarizes common issues with Flasher tools and the corresponding solutions.
Q: The main screen does not populate with the proper Flasher information
A: See Figure 55. This may indicate a problem with the connection between Flasher and the computer
Verify that the Flasher tool has power and that the Flasher serial cable is connected to the computer.
Additionally, check that the communications port selected in the
‘Communications’ section of the ‘Options’ menu is set to the correct port (i.e. the port to which the Flasher tool is connected).
Figure 55. Main Screen does not Populate
Q: The Flasher tool’s LED is red
A: Disconnect and remove power from Flasher. After a few seconds, reapply power to Flasher. Connect it to the unit controller again, verifying that the triangle on the 10pin connector of Flasher is properly installed on the keyed connector on the unit controller’s 10-pin JTAG port (see Figure 32).
Q: After applying power, the Target VCC field changes to a value that is too low
A: See Figure 56. This could indicate a communication error between Flasher and the unit controller. Verify that the Flasher 10-pin connector is properly connected to the keyed 10-pin JTAG connector port on the unit controller. Also verify that the unit controller is connected and powered properly. See Figure 7.
