CITY
MULTI is extremely flexible, delivering simultaneous cooling
and heating (R2-Series) to any number of rooms and building
configurations. Yet it’s remarkably easy to operate thanks
to the CITY MULTI Controls Network (CMCN), featuring direct
digital control technology. The controllers are easy to program
and operate, providing a host of functions for the ultimate
in comfort and energy saving capability. The controllers are
wired into the system via a two-wire, shielded cable for ease
of installation and reliable operation.
CITY MULTI Controls Network (CMCN) uses Mitsubishi Electric’s
advanced M-NET controls network
Mitsubishi Electric’s reliable high-speed communication
bus, M-Net, allows data to flow in large capacities to ensure
optimized performance of the system. Each component is integrated
on the M-Net for precise control of the temperature by regulating
the output of the outdoor unit capacity to match the needs
of each comfort zone.
The CMCN manages up to 2,000 indoor units from a single
network PC (with our TG2000 software) in terms of operation,
monitoring, scheduling (daily, weekly, and yearly), error
email, personal browser, tenant billing, and maintenance
diagnostic information. The CMCN puts individual, personalized
comfort in the hands of the tenants and the building manager.
Our TG-2000 integrated system software provides the ultimate
in building management by allowing input of the building’s
floor plan with illustrative icons for the CITY MULTI indoor
units. This software in conjunction with a maximum of 40
G-50A Centralized Controllers empowers the building manager
to control the HVAC system for multiple buildings in a business
park, educational campus, or retirement facility.
Tenant billing
The TG-2000 software configured with the tenant billing
option and interconnected with a RS-485 watt hour meter
can calculate the energy consumption relative to the each
outdoor unit on a per-tenant basis and generate a per-tenant
energy bill.
G-50 Centralized Controller
The G-50A Centralized Controller is capable of controlling
a maximum of 50 indoor units across multiple CITY MULTI
outdoor units. The G-50A Centralized Controller is approximately
5" x12" in size and is powered from a power supply
unit (PAC-SC50KUA). The G-50A Centralized Controller supports
operations that supersede control of the remote controllers
and include system configuration, daily/weekly scheduling,
monitoring of operation status, and malfunction monitoring.
Remote Controllers
Each indoor unit may have one or two remote controllers
or none at all. The remote controllers allow the temperature
set-point to be changed as well as the modes for Heat/Cool
and Fan. On/Off control and Vane control are also possible.
The remote controllers are wired into the communication
bus at the indoor unit. These controllers can be monitored
and operated from a central controller or a computer.
