The low installation height of only 200 mm allows the SEZ-M unit to be installed without problems even in small ceiling spaces. Once the unit is installed, only the air inlet grill and exhaust vents are visible.
The use of a drain pump makes it possible to pump condensate to a height of 550mm. This significantly increases the flexibility of installation design.
The unit can be equipped with a Wi-Fi adapter and controlled remotely via smartphone, tablet or PC using the control software MELCloud.
Wired Remote Control connectable (optional)
The unit can be equipped with a cable remote controller.
The weekly timer can configure up to four individual switching points for each day, enabling flexible switch-on and switch-off of the unit. A temperature specification can also be provided for each switching point to ensure demand-oriented and energy-saving control.
The on/off timer can be used to configure fixed switch-on and switch-off times.
Ensures the optimum air volume depending on the output requirements. If a high output is required shortly after switchon, the unit automatically switches to a high stage. The air volume is automatically reduced once the desired temperature is reached.
Filters coarse dust (>800 µm) from room air and prevents contamination of the heat exchanger.
Plasma Quad Connect filter
Plasma Quad filter technology ensures highly effective air purification. Plasma ionisation and the electrostatically charged filter ensure that even the smallest particles (PM2.5; <2.5 μm) such as pollen, viruses, mould, bacteria and allergens are separated and rendered harmless.
The integrated winter regulation enables cooling mode even at low outside temperatures. The outdoor unit fan speed is automatically reduced in order to maintain stable condensation pressure. If the outdoor unit is exposed to strong winds, then a wind protection panel is required.
The heat pump function enables energy-saving heating of the rooms. High efficiency even at low temperatures leads to low energy consumption, and conventional heating systems can be replaced with heat pumps in many cases.
Fresh outside air can be supplied to the room via the standard connection, with the air volume equating to as much as 10 % of the rated air volume of the respective unit. A booster fan is required in order to supply outside air.
When the voltage is restored, the units automatically start up with the previously selected settings. This ensures a high level of operational reliability.
Drain Lift Up
The units feature an integrated condensate pump as standard for easy condensate removal. The delivery head is determined by the indoor unit type.
R32 (difluoromethane [CH2F2]) belongs to the group of HFC refrigerants and has been used as a component of R410A refrigerant for many years. Given its GWP of 675, it already meets the requirements of the F-gas Regulation for the year 2025.
The German Building Air Conditioning Association (FGK) has bestowed its quality seal for room air conditioning units on the split air conditioning unit
The outdoor unit is equipped with energy-saving inverter technology
The inverter outdoor unit is equipped as standard with Replace technology, which enables easy reuse of existing R22 and R407C pipes.1 1See our M-series design documents for information on the compatibility of existing pipe cross-sections with the new units.
