Our HRV came with the most basic controller. It had the furnace fan running 24/7. As the furnace is on the same level, right near our bedroom, the fan is quite loud. After some research I found this digital controller with a lot more options. We are able to have the HRV run on a 10 min on, 50 min off cycle. This time gives us quiet and the proper humidity control! I had to mount it vertically to cover the original control electrical box, but it still operates properly, just have to read it sideways- no issue! It was very easy to install.
