Simple and Effective Control
Interactive "A-Control" makes system management easier than ever. Features like connectivity
to building air conditioning systems, quick, precise selection of indoor unit functions and a selfdiagnostic system for indoor/outdoor units reflect Mitsubishi Electric's promise to provide optimum comfort and performance.
Compact, Functional System
Advanced component and system design design technologies have been introduced to produce
some of the smallest and lightest rooftop air conditioning systems in the market.
FEATURES
Highly Efficient operation
Labor Saving Installation
The EER (Energy Efficiency Ratio) on These models is
greatly improved by revised design specifications and
by being manufactured stringently to Mitsubishi Electric high quality standards.
Because of the single unit configuration, all refrigeration work can be omitted.
The unit operation can commence immediately after
connection to the power supply, drain piping, ducting
and control system.
Minimum Floor Space
The PRH series feature a compact design and has been
succeeded in reducing more floor space.

Enhanced System Control and Operation Ease
Flexible Function Setting from Remote Controllers
Remote Controllers can now be used for the selection and setting of functions such as fan speed, air outlets, vane setting etc. which were previously set from the indoor unit base board. Setting canges can also be made very easily at the
installation stage.

System Compatibility
"A-Control" interactivity between indoor and outdoor
units enables the system's self-diagnostic function to
be used for examining the entire system; even abnormalities in the outdoor unit will be shown on the remote controller display. Improvements in display details make more accurate and timely responses for
maintenance and repair possible.
"A-Control" technology offers compatibility so that systems of the series can operate as part of the MELANS
building air conditioning management system. Once
connected by a special adapter (optional), the systems
respond to commands given from the MELANS control
center. Remote controller can also be used for general
system control.
