SAVE VTR 250/B is adapted for ventilation of smaller houses and apartments with an area of 140 m². Left and right handed models are available.

SAVE VTR 250/B is a unit with white painted double skinned panels and comes with complete control functions. The unit is equipped with a high efficiency variable speed rotating heat exchanger and a moisture transfer function that regulates the rotation speed of the rotor. Energy efficient fans with EC motors as well as low-pressure filters reduce the energy consumptions and gives low SFP factor (Specific Fan Power) and low sound. The built in humidity sensor in extract air can be used for demand control.

Connection to an external cooker hood is available on the top of the unit. This makes the unit well suited for apartment buildings where the extract air from the cooker hood is challenging. 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.

All settings and features are accessible via the SAVE Touch control panel which is integrated in the front door. The panel is a color touch screen with a user friendly interface. The option for connecting one or more external control panels is available. In addition, control panel has separate user level for authorized installers and service personnel.

The home screen displays information such as airflow, temperature, air quality and active functions. You can select between MANUAL and AUTO mode or choose preferred settings from the pre-configured user modes.

SAVE Touch AUTO mode has many functions available that regulate the airflow according to CO2, presence, humidity, schedule etc. The demand function control gives effective and economical operation to ensure best indoor air quality. Alarm symbols indicate possible malfunctions and issues direct alerts if anything needs to be rectified.

The unit comes with built-in electric reheater.

External connection board that has prewired inputs and outputs allows easy installation and setup of external sensors as well as for external heaters / coolers and other accessories.

The unit is delivered with low pressure bag filters:

• Supply air filter F7/ePM1 60%

• Extract air filter M5/Coarse 70%

Low pressure bag filter G3/Coarse 50% is available as an accessory for extract air filtering.
