This defrost controller ended my nightmare! Now my central heat pump goes into defrost when needed quietly and efficiently! A must for those who live in colder climates where frost and ice is a problem. My unit doesn’t struggle anymore! The best part it can be set to your liking and has a digital screen. You know what temp your coil and ambient thermistors are. The high and low pressure switches are also connected to controller. I can’t stress how great it works! The only downside it takes a knowledgeable HVAC person to install it.

The controller installed easily and is working very well. I would highly recommend this universal defrost controller. The the digital display of mode, ambient temperature and coil temperature makes monitoring the status of the heat pump outdoor unit very easy.
