DESCRIPTION

Smarty 3X P 1.1 designed for ventilation of apartments up to approximately 150 m2.

Smarty 3XP has 2 versions: Smarty 3XP 1.1 and Smarty 3XP 1.2. Version 1.1 is equipped with a control board with more connections for external devices: an extra connection for a second electrical heater and a second RH or CO2 sensor. In addition, pressure switches are installed on the 1.1 version for constant air flow/air pressure modes.

Low height (324 mm) of Smarty 3X P 1.1 allows the installation of it under the ceiling.

An efficient plastic counter-flow heat exchanger reaches 84.8 % of the heat recovery rate according to Ecodesing calculations. EC fans use only 0.278 W/(m³/h).

Airtight casing from EPP minimizes leakages both internally and externally. Airtightness is tested at the production line thus ensuring that no smells from the extracted air will return to the premises. Due to EPP insulation unit weighs only 53 kg, thus making installation under the ceiling easier.

Standard filter set: Coarse 65%. Optionally ePM1 70% supply air filter is available for efficient filtration of pollens and combustion particles.

Smarty HRVU uses an intelligent algorithm for frost protection. Frost protection is activated from -2C. The unit can use defrosting algorithms as airflow disbalance for defrosting up to or lowering of airflow rate (up to -15C)). External pre-heater also can be connected and used for frost protection.

The HRVU can be controlled by an external control panel (accessory), via the internet (accessory required), or via mobile app (accessory required). The timer is integrated into the unit's control board for energy-friendly control. External CO2, relative humidity, and presence sensors can be connected for automatic ventilation control.
