In this video, we explain how to troubleshoot relays in our greenhouse controllers. The model shown in the video is the AegisTec, but a similar procedure can be used for other models.
We recommend relays be changed every 2-3 years to account to normal wear and tear. It is also a good practice for growers purchase a few relays to have on hand, in the event one in a controller goes bad.
