Rated 4 out of 5 by gjkodis Expensive, but worth it
I needed make-up air for two new bath fans, and this unit works perfectly with the Broan Smartsense controllers to automatically open and close the damper when called upon. There were communication issues without the phase coupler, so either make sure you have all the Smartsense controllers on the same phase or purchase a phase coupler separately.
