Features

Compact ventilation unit with heat recovery for floor-standing installation in indoor areas, including control system, fully wired. Universal installation with external air connection on the left or right possible. Continuous operation at low external air temperatures optionally possible through modulating bypass in conjunction with a reheating register, electric preheating or disbalance control. For increased comfort temperature requirements, an electric or hot water reheating register can be installed in the unit housing as an option. Housing: Panel construction made of aluzinc sheet metal, thermally optimised to minimise thermal bridges. Double-walled panels made of aluzinc sheet metal, insulated on all sides with 50 mm mineral wool for optimum heat and sound insulation, corrosion-resistant coating (class C4) on the outside (RAL 7047), galvanised on the inside. Enclosure classes according to DIN EN 1886: T3/TB2/D1, generous inspection openings on both sides of the unit for easy access to all unit components and optimum cleaning and maintenance options. Condensate connection option at the bottom of the unit: 1 x exhaust air side, 1 x supply air side, DN 32 mm. Stainless steel condensate tray with integrated slope. Eurovent-certified cross-counterflow plate heat exchanger made of aluminium with a 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 odour transfer. The heat exchanger module has a standard automatic bypass flap mechanism with complete coverage of the heat exchanger for free cooling (night cooling) and cold recovery in summer. Fans: 2 direct-drive EC motors, class IE4 with very low SFP values, dynamically balanced and vibration-damped in the unit. Stepless control via 0-10V signal. Plug connections on all electrical components to simplify maintenance work. Filters: Two large-area, pressure loss-optimised cassette filters are installed as standard (outdoor air ePM155% (F7) and exhaust air ePM10 50% (M5)). Use up to filter class ePM1 80% (F9) in the outdoor air and ePM1 55% (F7) in the exhaust air is optionally possible. In addition, a pre-filter of class ePM 10 50% (M5) can be used in the outside air directly in the unit. 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 at the top 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 register (cold water or change-over). 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 analogue 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.
