The Highest Standards of Manufacturing
All products conform to the Certificate
Europe directives (Machinery Safety,
Electromagnetic Compatibility and Low
Voltage), as required throughout the
European Community, to guarantee
correct standards of safety.
In order to guarantee the very highest standards and
performance, we manage every stage in the
manufacturing of our products. Throughout the
production process we maintain strict control,
starting with our extensive resources in research
and development through to the design and
manufacture of almost every individual component,
from molded plastics to the assembly of units and
controllers.
EUROVENT CERTIFICATION
Quality Controlled from Start to Finish
Our highly trained staff and strict quality control
methods enable us to produce products with an
exceptional reputation for reliability and efficiency,
maintained over many years. As well as CE
certification and ISO 9001, several products ranges

SK2019 FMCD-V-ECM-001
General Description
This High- Wall Unit is designed to meet and exceed demanding requirements for efficiency, quiet operation and
appearance. The sleek profile and elegantly styled cabinet complement interior design theme, while the microprocessor
assures accurate environmental control.
Cabinet ~ the stylish cabinet is constructed of durable flame resistant acrylonitrile-butadiene-styrene (ABS) plastic. The
silver white color and rounded corners provide its modern look.
Water Coil ~ the water coil has a large heat transfer surface and utilizes the latest fin profile technology. It combines an
advanced technology approach with the security of a traditional design regarding tube thickness. The coil is constructed
with seamless copper tubes and headers. The tubes are mechanically expanded into corrugated aluminum fin material for a
permanent primary to secondary surface bond. The coil is tested at 25 bar and recommended for operating at 16 bar. It
includes manual air vent and water purge valve.
Integral Hoses ~ an integral hose is a synthetic elastomer tube, with stainless steel outer braiding and brass
connectors, which enables quick, low cost connections with no brazing.
Blower and Motor ~ the unit incorporates only specially designed and tested EC motors, allowing the blower wheel to
provide optimum performance in airflow-efficiency and quiet operation.
Filters ~ washable, easy-to-remove, fine mesh air filters are standard to all high-wall models. Tabs located on the front of
the unit can be unsnapped, allowing the filter to be easily slid downward and removed. No tools are required, nor any
dismantling of the equipment.
Air Grille Distribution ~ all units are equipped with both deflector blades and independent directional vanes, enabling
supply air to be automatically distributed, and air flow and direction to be customized.
Microprocessor Control ~ see sections D and F for control specifications and details. The main design features include:
~ FCEER rating class: A/B.
~ FCCOP rating class: B/C.
~ High efficiency EC motor with PID algorithmic processing in auto-mode.
~ 2-pipe, 2-pipe with booster electric heat, 2-pipe with primary electric heat, 4-pipe with 4x2 device installed.
~ Cool, Heat, Auto, Dehumidifier and Fan modes.
~ Sleep, Auto-Fan, Daily Timer, Auto-Restart with memory functions.
~ User friendly remote control handset.
~ Heat and cool temperature protections and safety cut out.
~ 2-way and 3-way on/off valve control.
~ Addressable control and error diagnostics (Master-Slave) for sub-networks of up to 32 units, with IR handset as global
control interface.
~ Wired wall pad controller (optional) with 7-day programmable timer, real-time clock, network control (global and
addressable) and error diagnostics.
~ Manual control panel in cabinet.
~ Auxiliary switch for cooling and heating signal.
~ Occupancy (remote on/off) contacts / economy mode contacts.
~ Open Modbus communication protocol.
~ Local PC host control solution (optional).
