Combi 185 BP • Supplies fresh air and domestic hot water for the entire family • Contributes to the heating of the home through the supply air • Automatic summer bypass Combi 185 BP is a complete unit that consists of a ventilation and a tank segment containing a high-performance counterflow heat exchanger with a heat recovery factor of up to 95%, a hot-water tank with a capacity of 185 litres and a built-in heating coil designed for connection to a solar collector or central heating, a combination heat pump for simultaneous heating of supply air and domestic hot water, as well as energy-efficient supply air and extract air fans with backwards-curved blades and EC motors. The standard unit includes an G4 supply air and a G4 extract air filter and a complete OPT312 control unit with a stylishly designed control panel. Combi 185 BP is used as a ventilation heat pump in dwellings that require a high heat recovery factor and low energy consumption, while using the recovered energy from the exhaust air for heating the home's supply air and domestic hot water. Energy is first recovered by the counterflow heat exchanger, upon which residual energy is recovered by the heat pump. Combi 185 BP can produce a max. air volume of approx. 320 m3/h at 100 Pa. The unit can be used for homes with an area of up to approx. 300 m2 with an air change of 0.30 l/s per m2 of heated floor area assuming there are no requirements for max. power consumption. Types • Combi 185 BP S: Small compressor • Combi 185 BP LS: Large compressor For the Optima 301/312, a control panel called Optima Design can be purchased. Optima Design is a stylish white control panel that provides access to the most important functions via a simple user interface with push buttons. Please note that displays are sold separately.

Capacity Capacity lines are based on the average of supply air and discharge air volumes in a unit. The curves indicate the average external pressure available at a given air volume. SFP-curves are reduced by 10 Pa using PET exchanger and 15 Pa using F7 filter at the fresh air intake. SFP factors COMBI 185 BP – measured pursuant to EN13141-7 (G4/G4:ALU) Pa Temperature efficiency "Dry" temperature efficiency pursuant to EN 308 and in the event of identical air flow on the fresh air and discharge air side. The icing of the heat exchanger at low outdoor temperatures has not been taken into...
