Introduction
Introduction
DANGER
Electric shock hazard. Can cause personal injury or equipment damage.
This equipment must be properly grounded. Only personnel who are
knowledgeable in the operation of the equipment being controlled must
perform connections and service to the unit controller.
CAUTION
Static sensitive components. Can cause equipment damage.
Discharge any static electrical charge by touching the bare metal inside the
control panel before performing any service work. Never unplug cables or
control modules while power is applied to the unit controller.
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. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be
required to correct the interference at his or her own expense. Daikin
Applied disclaims any liability resulting from any interference or for
the correction thereof.
Introduction
The purpose of this document is to describe how to download
MicroTech® III water source heat pump (WSHP) unit controller,
I/O expansion module, and network communication software. It
also explains what programming tools are needed to install and
veriify that the correct software has been installed correctly.
It is assumed that the unit controller and optional modules have
been installed and are functioning properly. If necessary, refer
to the Reference Documents section for installation manual
details.
This guide is organized into four main sections:
1. WSHP Unit Controller and I/O Expansion Module
2. BACnet Communication Module
3. LonWorks Communication Module
4. Troubleshooting Guide and FAQ
The Troubleshooting section is a helpful reference with tips on
solving potential hardware and/or software issues, along with
detailed descriptions of WSHP unit options by model number
and associated equipment configuration hardware jumper
settings.
Terminology
•
MicroTech III Unit Controller.
The baseboard attached to
the WHSP which is downloaded with the most current
version of application software for unit operation. The
terms MicroTech III or MTIII are also used to reference
the I/O expansion module and communication modules in
addition to the baseboard.
•
I/O Expansion Module:
Optional daughter board that
provides additional input/output capability for secondary
compressor, multiple speed fan, secondary heating, and
dehumidification control. The I/O expansion module is
attached directly to unit controller when these options
have been selected with the unit.
• Custom I nterface Cables
:
Two different cable kit
assemblies have been designed by Daikin for use with
the programming tools needed to download software to
the baseboard part number 668105611 or I/O expansion
module part number 668105711. One cable assembly
supports the Renesas E2 Lite/E1 programmer. A separate
(but similar) cable assembly supports the Renesas E8a
programmer. Each custom cable assembly includes a
small PCB with 14-pin port for connection to the Renesas
programmer and either a 6-pin or 10-pin port (depending
on WSHP controller hardware version) for connection to
the baseboard or I/O expansion module.
•
JTAG:
The hardware interface required for downloading
older versions of unit controller and I/O expansion
module software. JTAG refers to both the connector port
attached to the unit controller as well as the cable used
to download software to the BACnet communication
module.
• Renesas Flash Programmer (RFP) Tools:
The
software used with the Renesas E2-Lite or E1 hardware
to program the current RL78/G13 family of Renesas
microcontrollers. The RFP tools support the R5F101FE
MCU used on WSHPs with hardware PNs 668105611
and 668105711.
•
.rpj File:
The project file type used used to specify the
RFP software configuration settings.
• Renesas Flash Development Toolkit (FDT): The
software used with the Renesas E8a hardware
to program the obsolete 740 family of Renesas
microcontrollers. The FDT supports the M38507F8A MCU
used on WSHPs with hardware PNs 668105601 and
668105702.
• Segger Flasher Tools (Obsolete): The software used
with the Segger Flasher5 hardware to program the 740
family of legacy Renesas microcontrollers. Flasher5
supports the M38507F8A MCU used on WSHPs with
hardware PNs 668105601 and 668105702.
• Segger J-Link / Atmel SAMBA Tools : The software
used with the Segger J-Link / Atmel SAM-ICE hardware
to program the BACnet communication module
microcontroller used on FCU/WSHP hardware PN
668105901.
•
.hex File
: The unit controller baseboard or I/O expansion
module software file. A separate .hex file is required for
each board.
•
.mot File
: The unit controller baseboard or I/O expansion
module software file. A separate .mot file is required for
each board.
•
.bin File:
The BACnet communication module firmware
.
•
.nxe File
: The LonWorks communication module
firmware.
•
U-10:
The network inteface hardware used for LonWorks
communication module software downloading.
•
MCU:
Refers to the microcontroller unit chip. It uses
embedded Flash memory to store and execute the
application.
