Our CITY MULTI Controls Network
makes it easy to manage your building
CITY MULTI
®
CONTROLS NETWORK
The CITY MULTI Controls Network (CMCN) manages up to 2,000 indoor
units from a single networked PC in terms of operation, monitoring, sched-
uling (daily, weekly, and yearly), error email, personal browser, tenant billing,
and maintenance diagnostic information. The CMCN puts individual, per-
sonalized comfort in the hands of the tenants and the building manager.
Flexible design for customized,
individual zone control
Building owners and engineers can select from a wide variety of remote
controllers and timers to satisfy the exact level of tenant control on a zone-
by-zone basis, while providing the ultimate in individualized control. Each
indoor unit may have one or two remote controllers or none at all.
The remote controllers allow the temperature setpoint to be changed along
with On/Off control and fan speed adjustment. Mode selection (Cool/Heat/
Dry/Fan/Auto) and vane control are also possible, depending on the
remote controller and indoor unit.
The CMCN enables the room temperature to be sensed either at the remote
controller in the zone or the temperature to be sensed at the actual indoor unit
simply by changing the dip switch setting on the indoor unit. Depending on the
type of the remote controller, the remote controller can be physically located in
the controlled zone or in a physical location different than the controlled zone
to meet the customer’s specific requirements.
The versatility of the CMCN customizes each building’s controls
network to address the specific design and tenant requirements,
while providing unparalleled comfort conditioning.
Optional easy-to-use control via
PC web browser
With the CMCN, you have the option to control multiple CITY MULTI
systems with the AG-150/GB-50/GB-24 Centralized Controller(s) from a
PC’s web browser. From Internet Explorer
®
on a PC, the building man-
ager can now monitor, operate, and schedule (daily, weekly, and yearly)
the HVAC system through the AG-150/GB-50/GB-24 network. Emails
can be automatically generated when an abnormal condition is detected
on the system with the source address and the error code. The building
manager can enable tenants to control their own individual zones via
a personal web browser on their networked PC in conjunction with the
AG-150 or GB-50 centralized controllers.
Easy installation
It’s a simple, two-pipe system with simple, non-polar, two-wire control
connections. All components are daisy-chained and addressed onto
the M-NET communication bus. It all adds up to less labor and
materials with quicker installation.
Single-source control for up to
2,000 indoor units
From a single networked PC configured with our TG-2000 software,
you can control up to 2,000 units. 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 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 RS-485 watt-hour meter(s) can calculate the
energy consumption relative to each outdoor unit on a per-tenant
basis and generate a CITY MULTI energy fee per-tenant.
System integration
Not only can our CMCN act as a stand-alone building management
system, it can also integrate with existing systems via LonWorks
®
or
BACnet
®
interfaces.
TG-2000 software manages up to 2,000 indoor units
using centralized controllers and software licenses.
