I just want to shout out Vexus (Tim) and company for the excellent customer service. Any issue I have had they have been on top of it, this one was the breaker on the back by the batteries. I lost power to the control panel, Tim took me through the steps and found the breaker was bad and two days later UPS dropped of a new one. I have had some other minor issues that were handled the same way...Fast, and I thank the people at Vexus for the speedy customer service. It make a difference.
