Training
Mitsubishi Electric has trained
more than 12,000 contractors and engineers on VRF technology. We
offer training courses nearly every week at each of our five
Training Centers. In addition, we have a Training & Development
(T&D) website driven by our Learning Management System (LMS).
The T&D site offers you:
- CEUs for commercial and
residential training
- Password-protected accounts for
all training customers
- Online registration available for
all of our training programs
- 24/7 access to your Mitsubishi
training history
Infrastructure -
Network of Distributors & Contractors
MEHVAC has built an
infrastructure to support VRF in the US and has the largest
infrastructure of distributors & contractors in the US VRF
category, more than 1,000 distributor branch offices through the
United States.
Mitsubishi has trained more than
12,000 contractors and engineers on VRF technology.
Mitsubishi Electric Diamond
Alliance program is designed to create a strong, cohesive
infrastructure of Distributors, Engineers and Contractors in order
to provide outstanding support to our customers:

Mitsubishi Diamond Designers are
engineering firms or design/build contractors with in-house
engineering staffs that have received training for the design of
Mitsubishi Electric's CITY MULTI systems. The Mitsubishi Diamond
Designer program is a recognition program for those who have
achieved the highest level of training in order to better serve
their clients.
Mitsubishi Diamond Dealers are
independent contractors that have reached the highest level of
accreditation from Mitsubishi Electric HVAC Division. They have
successfully completed factory training in the areas of
applications, sales and service for the Mr. Slim product.
Tools - Design and
Monitoring Systems
Mitsubishi Electric systems are
easy to manage and control. Mr. Slim and CITY MULTI indoors units
feature wireless remote controllers, depending on the model style,
to control temperature, fan speed and more.
The CITY MULTI Controls Network
(CMCN) can manage up to 2,000 indoor units from a single networked
PC and provides control over operation, monitoring, scheduling,
error email, personal browser, tenant billing and maintenance
diagnostic information. The tenant billing option can calculate the
energy consumption per system or per indoor unit (depending on how
your system is configured), allowing you to bill HVAC electricity
consumption per tenant.
Design software makes designing
with Mitsubishi VRFZ systems quick and easy. Drag and drop
components complete the design. Built-in safeguards protect against
exceeding limitations and shows if there is an error.

Assuring line lengths, maximum
connected capacities, component selection, control scheme, etc. are
all within the system requirements. System design conditions are
easily entered such as indoor and outdoor design conditions for
both heating and cooling. Controls and Lossnay ERVs can be set up
by selecting the style and dragging and dropping them into the
design. The system is summarized in an Excel spreadsheet, and
includes all design parameters, equipment list, line sizes, indoor
unit operating capacities, additional refrigerant based on the line
lengths, control scheme with addressing and more, simplifying job
quotes and tracking equipment lists.
With the help of AutoCAD, AutoCAD
LT or REVIT, a schematic is generated that includes all the
requirements to make installation a breeze - includes line sizes,
wiring diagram with indoor units grouped as designed, labels indoor
units, addressing, etc.
Maintenance software monitors
pressure and temperature readings from system sensors in order to
control system LEV settings and all connected indoor units. The
Energy Modeling Software tool helps you compare energy efficiency
of VRFZ to traditional systems and lifecycle cost savings in
various climate zones.
Monitoring and
Maintenance Software
Mitsubishi's easy-to-use,
Windows® based Maintenance Tool software allows technicians to
monitor and collect CITY MULTI system data and control various
functions of the system for maintenance purposes.
The Maintenance Tool software used
to monitor pressure and temperature readings from CITY MULTI system
sensors, display and control system LEV settings and display and
remotely control all connected indoor units. The software also
allows the technician to record and save system monitor data for
the purposes of trending and system analysis offsite as well as
display malfunction logs and email error reports to personnel
responsible for servicing the system.
System monitoring is accomplished
through direct connection between your PC and the M-NET bus line
using the MN-Converter or by connecting remotely to a system
centralized controller such as the AG-150, GB-50 or tc-24 via a
TCP/IP network, or via a remote dialup connection.
