ECO 375 • Focus on energy optimisation – low energy consumption • Compact installation dimensions The ECO 375 is a ventilation system for heat recovery with a high-efficiency countercurrent exchanger with a temperature recovery rate of up to 96% and fans with energy-saving EC motors. The ECO 375 is typically used in homes or small businesses where the emphasis is on comfort and low energy consumption. The ECO 375 is suitable for installation in larger homes or smaller business premises with an area of up to 350 m2. The ECO 375 stands out by being particularly energy-optimised and adapted to the stringent requirements of the BR18 low-energy class. Despite the compact installation dimensions, adapted to a standard 60x60 cm module, the performance of the ECO 375 matches systems with a significantly larger footprint. As standard, the ECO 375 is supplied with G4/Coarse filters on the outdoor air intake and on the exhaust air (the F7/ePM1 filter is supplied as an accessory). • Built in preheater and water level switch optional For the ECO 375, a built-in 1200 watt electric preheating surface can be selected as an accessory, ensuring a balanced air supply even in very cold outdoor temperatures and with a minimal energy supply. A built-in condensate water level switch can also be selected, which switches off the ventilation system in the event of problems with the condensate drain and gives an alarm via the display. The system comes with an Optima 270 control: • Passive comfort cooling with fully automatic 100% bypass. • Reduced energy consumption by means of modulating humidity control and calendar programme. • Connection of electric preheating or post-heating surface, which adjusts the temperature according to need. • Can be connected to a BMS system via Modbus communication. • Integrated RJ45 connection on the control board for cloud connection of the system. • Can be used without a display or with the option to connect either of two display types (Basic/Touch). • Built-in data logging and the option of

Capacity The capacity lines are based on an average value of supply air and exhaust air volumes in a unit. The graphs indicate the average external pressure available at a given air volume. Power consumption for control is not included in the SFP value (approx. 6 watts). SFP factors ECO 375 – measured according to EN13141-7 (G4/G4:ALU)

Temperature efficiency “Dry” temperature efficiency at the same air flow on the outdoor air and exhaust air side. No account has been taken of any icing on the heat exchanger at low outdoor temperatures. Temperature efficiency according to EN13141-7 % 93 88

Automatic control Control panel – Optima Touch The ECO 375 comes with the Optima 270 automatic control. The Optima Control comes with a factory setting, which makes it possible to put the system into operation without first having to configure the system’s operating menu. The factory setting is just a basic setting that can be changed to match your operational desires and requirements for your home. The ECO 375 can be supplied with the following accessories: • Genvex fire and district heating control. • Water-based post-heating surface, incl. motor valve, or electric heating surface for...
