Heat recovery unit designed for dwellings where ventilated area is up to apx. 240 m2.
The SAVE VSR 300 is double skinned, fully insulated and with complete control functions, high efficiency variable speed rotating heat exchanger with a moisture transfer function that regulates the rotation speed of the rotor due to freezing and moisture transfer back to supply air. Thermostat operated re-heater battery and filters. Energy efficient fans with EC motors will reduce energy consumption for transportation of ventilation air by apx. 50 % compared to traditional AC motors. Modern technology is contributing to a low SFP factor (Specific Fan Power) as well as an efficient design of the unit.
The unit will automatically alternate between normal operation with heat recovery and summer operation without heat recovery. This solution will also automatically recover chilled indoor air (from cooling).
Commissioning of the unit will be done from one or more CD panels. A start-up wizard will make the commissioning easier, which can avoid that the unit is running at wrong conditions. Symbols and text in the display will indicate chosen settings; Supply air temperature and fan speed. Commissioning of airflow on supply and extract, will be done at start-up but can be set from the menu settings as well. Timer-function for automatic change between day and night operation is integrated. Setting of filter period is also available. Alarm signal will indicate possible malfunctions.
The CD panel also has a user level for authorized installers and service personnel. The CD panel is connected to the unit by means of cable with quick connector (modular plug), on the side of the unit.
The unit is provided with outputs for control of external hot water or cooling battery and comes with built-in humidity sensor in extract air that enables demand control regulation with respect to moisture. It also has functions availably for external demand control that gives effective and economical operation. For instance, CO2, presence or humidity sensor.
The unit can be installed in upright position on the floor or horizontally on the ceiling.
Ceiling mounting kit is available as accessory.
The unit is delivered with supply air filter F7 and extract air filter G3. Option for G3 supply air filter is available.
CD panel and cable are also supplied with the unit.
