Our DC Speed and capacity controlled type air conditioners use environmentally friendly refrigerant R410A,
lso prvides one of the highest energy ef ciency ratings in the industry. Output of the compressor and therefore
the energy input requirements are constantly monitored and adjusted at the most optimum level for the
given indoor and outdoor environmental conditions and the users’ desired demands from the system.

Microprocessor control system contains several enhanced software features to make the operation of the
system to work with poor power grids and varying environmental conditions.
Low start up current, 3 minutes automatic start up after power cut downs and low energy consumption.

Random pitched blowers, skewed blade fans, motors with permanently lubricated ball bearings and
special vibration absorbers on the compressor allow operation of the system with ultra low noise from
both the indoor and outdoor units.

Automatic 3 fan speed indoor fan motor with its Turbo Operation Mode can achieve the set room
temperature very quickly, while the ultra low speed mode provides a quiet operation. In
auto mode, system chooses the best suitable speed for the measured conditions, while all 3 speed
levels are also user selectable. Changes between fan speeds are smooth and virtually unnoticeable by
means of the IC controlled varistor driving the indoor motor.

System can be equipped with optional additional air puri cation devices, ionizer module, in addition to
standard equipment anti-mould treated washable return air filters.

Latest design and attractive appearance allows ease in maintenance and servicing.

Operational indicators allow the users to monitor the system working status.

Microprocessor is programmed to allow operation under wide range of input voltages from 180V~250V
and soft starting with lower current draw at each compressor start-up.

Optimized temperature setting for Telecom range between 19 to 39 degree C.

Auto-restart function keeps all settings in memory and automatically resumes the operation after a
power failure.

Compressor crankcase heaters and outdoor heat exchanger heaters are available as options for extreme
Nordic conditions, enabling the unit to work in very low ambient temperatures with much lessened
defrost frequencies. Both these optional heaters are electronically controlled based on the outdoor
ambient temperatures and a sophisticated logic.

Self learning defrost logic constantly monitors the defrosting requirements and automatically adjusts the
intervals between defrosts for optimum operation.

Anti Cold Air Function controls the operation of the indoor fan to avoid cold air drafts at system start-up
and defrost modes

Programmable TIME ON and TIME OFF function provides unattended operation of the system.

Hydrophilic material coated enhanced aluminum on the indoor heat exchanger provides for easy
drainage of the humidity and reduces air pressure drop through the coil

Acrylic coated enhanced aluminum ns on the outdoor heat exchanger extends the n life against
corrosion and allows easier rainwater wash-down as well as faster defrosts.

Copper tubing in all heat exchangers are made by using the latest developments in the technology
of inner grooved tubing by extending the area of heat exchange in a more compact coil, therefore
increasing the operational ef ciency.
