centralizedERVresidential

Compact unit with heat recovery for central ventilation of houses and apartments built upon pas- sive-house standards. High efficient cross counterflow heat exchanger with an efficien- cy of more than 90%. Latest EC motor technology with constant air flow regulation. This ensures that the adjusted air flow rate is preserved regardless of chang- ing resistances (e.g., dirty filters) on each operating level. KWL EC 270 Eco The economical solution for a wide range of application with an excellent cost/performance ratio. ■ Speed control □ Three speed operation via controller, integrated in the front panel. □ Three freely definable operating levels individually controllable via potentiometers. Adjustable speed ratio of supply/extract air. □ Disconnection via on/off switch on site or potentiometer adjust- ment. □ An LED signals operating condi- tion. filter change, frost protecti- on, supply air temperature lower than 5° C and error message. □ Activation of intensive ventilation level by additional external switch on site. ■ Summer operation Using exchanger cover plate, adjustable switching tempe- rature and can be deactivated.
