As the colder season and winter approaches here in the northern part of Sweden there is not much need for a fan to ventilate the observatory, but I want to be able to have the option of using it. I wanted a ventilation solution that was mechanical, and I also wanted a solution that was smart and that I could control. I opted for a bathroom fan with the ability to sense humidity and temperature and adjust fan speed accordingly. In this video I will show you the installation of the fan, including making a hole in the wall of the observatory. I will also give a brief tour of the electrics in the observatory.
