Heat recovery unit designed for dwellings where ventilated area is up to apx. 240 m2. 
Left and Right handed models available.

SAVE VTR 300/B is a white painted model with an integrated control panel in the front door. The option for connecting one or more external control panels is also available. Connection to an external cooker hood is available on the top of the unit. The extract air from the cooker hood is being by-passed, hence the heat exchanger is not being exposed to extract air from the kitchen.

The unit 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 consumptions. With these, up to 50% less energy consumption can be achieved in comparison to AC solutions, with the noise behaviour decreased by one-half. Modern technology gives low SFP factor (Specific Fan Power).

Commissioning of the unit will be done from the CD control panel in the front door or a separate external panel. 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. An external CD panel is connected to the unit by means of cable with quick connectors (modular plugs), at the top 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 is delivered with supply air filter F7 and extract air filter G3. Option for G3 supply air filter is available.
