NVR-1P
The NVR-1 ventilation controller is extremely suitable
to control a ventilation valve or curtain in housing with
natural ventilation. Depending on the temperature
measured and the delay time set the intake is opened
or closed. If there is a sudden temperature drop of more
than 2 degrees (thunderstorm), the intake is closed extra
quickly. The NVR-1P also has the facility to control
the heating.
