Technical Data
General Description
The product represents all-in-one solution for cooling, heating and dehumidification. It achieves high energy saving levels as it
can be combined with low-temperature heat generators such as heat pump, condensing boilers and solar collectors. With its
sophisticated temperature regulator, it guarantees thermal comfort in every season. It heats and cools extremely quickly and
once the desired temperature is reached it maintains it accurately and silently.
STRUCTURE
The bearing structure is made of galvanized sheet-steel with holes for attaching the structure to the wall/ceiling. The “V” type
drain pan is used in the unit which ensure the unit can be installed vertically and horizontally. Fire resistant insulation is fitted
internally to provide both thermal and acoustic insulation.
FASCIA
The RAL9010 fascia is made of steel-sheet with electrostatic coating which is resistant to rust, corrosion, chemical agents,
solvents, aliphatic compounds and alcohols.
AIR DELIVERY GRILLE
The air delivery grill is made from ABS, which color is RAL9010.
HEAT EXCHANGER
The heat exchanger is a highly efficient coil in which copper pipes and aluminum fins are fixed by mechanical expansion. Coil
connections are provided with an anti-torsion system, hand air vent and water purge valves.
Coils are tested at the pressure of 25 bar and recommended for operating at 8 bar.
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.
AIR FILTER
The air filter is made of ABS with Nylon filter. It is easy to removing and cleaning, which can be cleaned by rinsing with water
or by gently vacuuming it.
Microprocessor controls (EC-TOTAL type)
The PCB (printed circuit board) Modbus microprocessor controls functionality of the indoor fan motor, water valves (ON/OFF)
and electric heater (optional), to maintain room conditions at a user-defined set point. Temperature settings, fan speeds and
other control functions can be changed by either infrared handset or wired wall pad controller.
Electro-mechanical controls (EC-FLEXI type)
A 230VAC signal from the thermostat which working power is from L and N or from indoor room to terminal H/M/L supplies
power to limited PCB. When any of H/M/L is powered ON, the stepping motor is working and open the louver at maximum
position. When all of H/M/L is powered OFF, the stepping motor will close the louver. The condensate pump will run
continuously, as long as coil temperature is less than 15°C. Alarm notification and zone control function are available. 40VA
24vac transformer is equipped with unit optionally, which is used to supply 24Vac power to thermostat and modulating valve.
