Features

Compact ventilation unit with cross-counterflow heat exchanger, including control system, fully wired. For installation on the floor ceiling or in the false ceiling in indoor areas. Built-in electric preheating register to protect the heat exchanger from freezing at very low outdoor air temperatures. For increased comfort temperature requirements, an electric or hot water reheating coil can be installed in the unit housing as an option. Housing: Made of aluzinc sheet metal, insulated with 50 mm mineral wool for optimum heat and sound insulation. Corrosion-resistant coating on all sides, RAL 7047, corrosion class C4, galvanized on the inside. Housing classes according to DIN EN 1886: T2/TB2/D2. Inspection openings on the underside of the unit for easy access and optimum cleaning and maintenance. Additional inspection opening on the side for filter maintenance. 2 condensate connections DN 17.5 mm: 1 x exhaust air side, 1 x supply air side. Stainless steel condensate tray with integrated slope. Automatic bypass flap for free cooling can be activated. Temperature sensors for outside air, supply air, exhaust air, and in the heat exchanger for comprehensive monitoring of the operating status. Eurovent-certified cross-counterflow heat exchanger made of aluminum with high thermal efficiency of up to 90% in accordance with EN 308. The heat exchanger has a high internal tightness and is therefore particularly suitable for applications where there is a risk of odor transfer. Fans: 2 direct-drive EC motors, class IE4 with very low SFP values, dynamically balanced and vibration-damped in the unit. Infinitely variable control via 0-10V signal. Plug connections on all electrical components to simplify maintenance work. Filters: Two large-area, pressure loss-optimized cassette filters are installed as standard (outside air ePM1 55% (F7) and exhaust air ePM10 50% (M5)). The use of filters of filter class ePM1 80% (F9) in the outside air and ePM1 55% (F7) in the exhaust air is optional. The filters are monitored by means of dynamic, volume flow-dependent pressure monitoring. Control: The ventilation unit is delivered ready for operation with a versatile control system. The control system is easy to maintain, located in a connection box on the side of the unit, factory-wired, and function-tested. Two control elements (ECO and Touch) are available (required accessories). Control functions: Ventilation modes: Constant volume CAV, constant pressure VAV (accessories required), constant speed CRPM in % or via weekly program. Automatic ventilation mode/ventilation on demand (VOD) via humidity, CO2, or VOC sensors. Up to 18 sensors can be connected per ventilation unit. Free cooling, active cooling via cooling coil (cold water or DX). Temperature control, e.g. constant supply air, supply air controlled by outside temperature, room supply air cascade, etc. possible. Digital inputs for fire alarm and external switch (on/off). Digital output for collective fault signal. External fan control via two analog 0-10V inputs (supply air and exhaust air fan separate). Connection to the building management system via BACnet IP or Modbus TCP possible. Commissioning wizard for quick and easy commissioning of the unit and the appropriate accessories.
