2. INTRODUCTION
PRODUCT DESCRIPTION AND
APPLICATIONS
The MICROMASTER Eco and MIDIMASTER Eco
provides a range of variable frequency speed
controllers (inverters) specifically developed for
the Heating, Ventilation & Air Conditioning
(HVAC) industry.
Key design features include:
• Automatic energy optimisation
• Motor thermal overload protection
• Automatic switching frequency optimisation for
minimised acoustic noise generation
• Zero de-rating of motor
• Automatic motor tuning at switch-on
• Earth fault protection
• Short circuit protection
• Built-in chokes allow use of up to 150 metre
motor cables
The ability to easily control the speed of pump or
fan motors provides superior regulation and
control of the process, enabling optimisation of
room temperatures and personal comfort levels.
The Eco range combines ease of installation and
commissioning with low maintenance and
operating costs. In addition, the specific HVAC
product functionality (compared with similar
products aimed at “Hi-Tech” multiple applications)
means that product costs can be minimised, and
the user does not pay for features which are not
required.
Day-to-day operating costs can be drastically
reduced - up to 60% in some applications. Energy
consumption and associated emissions are also
reduced to the lowest possible levels.
ECO OPERATING INSTRUCTION
MANUAL
The Eco Operating Instructions booklet (which
should be read in conjunction with this manual)
provides basic information on equipment
installation and programming, to control the
functions of fans and pump motors. It is aimed at
HVAC Installation Technicians and Electricians
working and commissioning on-site, and is
intended to provide a quick, straightforward guide
to installing and simple operating of the Eco units.
ECO REFERENCE MANUAL
This Manual - The Eco Reference Manual is
intended for use by a wide range of HVAC
professionals. For example, the Eco Reference
Manual is to be used by Building Automation
Engineers to plan their equipment and cabling
schedules and estimate their material
requirements. HVAC Consultants may also use it
in order to compile the relevant portions of their
tender specification.
The Eco Reference Manual should also be useful
to electrical panel builders, building automation
control engineers, quantity surveyors / estimators,
electrical project managers, and maintenance
contractors.
