M-Net Addressing - Mitsubishi Electric BDT CITY MULTI Installation And Pre-Commissioning Booklet

M-NET ADDRESSING

All City Multi equipment that sits on the M-Net requires a numerical address. This address allows
the system to identify, control, log and allocate faults to an individual piece of equipment.
Addressing must be completed at the time of installation prior to commissioning.
The address setting is generally carried out by the installation electrician as the addressing rotary
switches are located in or close to the electrical terminal boxes.
The piping installer must clearly identify and label each item of plant with permanent marker or
other labelling system with the following:
• Address
• Indoor/Outdoor/BC Name
• Port Number (R2 equipment only)
ADDRESSING MUST FOLLOW THE PIPING AND WIRING SCHEMATICS.
Rotary Switch Operation
Addresses are set using numerical rotary switches. There are two rotary tumblers for address setting
- the 10's and the 1's. For R2 indoor units a port setting is required. This tumbler can be set from 1
to 16. For this tumbler, A=10, B=11, C=12, D=13, E=14, F=15 and 0=16.
NOTE: Be sure power is off before setting address settings.
Ensure no two addresses are the same as this will cause a fault and the system will not operate.
