ECO 400 • Focus on energy optimisation – low energy consumption • Well-suited to mounting in unheated rooms due to the high level of thermal insulation • Right/left version in the same unit ECO 400 is a ventilation unit for heat recovery with a highly efficient countercurrent exchanger, which has a temperature recovery rate of up to 96% and fans with energy-saving EC motors. ECO 400 is typically used in homes or small businesses where the focus is on comfort and low energy consumption. ECO 400 is well-suited to installation in large houses or small businesses with an area of up to 450m2. ECO 400 stands apart from other ventilation units by being especially energy efficient and adapted to the strict requirements of NZEB energy class. ECO 400 is especially well-suited to unheated rooms such as unused loft spaces due to the high level of thermal insulation. As standard, ECO 400 is supplied with G4 filters on fresh air intake and exhaust (M5/ F7 filter supplied as extra). ECO 400 can be equipped with a heat exchanger made from PET (plastic) or an enthalpy heat exchanger, where, in addition to heat exchange, it is also possible to recover the moisture from the exhaust air in the building. The unit is supplied with an Optima 251 controller: • Passive comfort cooling with fully automated bypass. • Reduction of energy consumption with the aid of modulated humidity control and calendar program. • Connection of electrical pre-heating or reheater (can be supplied integrated as option), which adjusts the temperature as needed/ wanted. • Can be connected to a BMS unit via Modbus communication. • Can be supplied pre-installed with internet gateway so the unit can be controlled

Capacity The capacity graphs are based on a mean value of the supply air and exhaust air volume in a unit. The graphs indicate the average external pressure available for a given airflow. The capacity lines do not change with the use of an enthalpy exchanger rather than an RC exchanger. SEL factors ECO 400 RC – measured according to EN13141-7 (G4/G4) 600 Power consumption Watt 200 160 100 %

Thermal efficiency values “Dry” temperature efficiency according to EN 308 and with identical air flow on the fresh air and exhaust air side. Potential formation of ice on the heat exchanger at low outside temperatures has not been taken into account. Thermal efficiency according to EN308

Control panel ECO 400 comes with Optima 251 print circuit board. The Optima Design control panel, that connects to the Optima PCB, comes with a factory setting that makes it possible to put the system into operation without first needing to set the system's operational parameters. The factory setting is only a basic setting that can be changed based on the customer's operational preferences and requirements for the building. ECO 400 can be delivered with the following accessories: • Genvex Automatic Fire Protection • Water-based reheating plate including motor valve for mounting in...
