The DVS 5E features summer and winter settings. In winter mode, the DVS 5E automatically speeds up to circulate available warm air from your roof space into your home. In summer mode, the system will automatically turn off when your roof space reaches a pre-set temperature, preventing your home from becoming uncomfortably warm.

Just like all DVS models, the 5E is calibrated to the size of your home. Further fine-tuning for your individual circumstances is achieved using the MORE and LESS buttons to adjust the airflow.

This control panel also features a warning light which will flash when the air filter is due to be changed.
