The Control Panel
The picture above shows the control panel. The temperature controller is at the top. Next to it are to lights to show when the mash vales are open. The row of switches and lights are to turn on and off each heating element and the pump and the main power. Even though the controller turns on and off the heating elements I added the switches to make sure they are only on when there is liquid in the tanks. The temperature controller can control up to eight loops, I have it controlling three. I purchased the controller from ebay.
