Bought some custom made stuff from @TheHarold at Harry’s Aquatics. Probe holder that mounts to an adjustable optic switch holder I already bought from Harry. The probe holder and switch holders slide up and down on a rod that mounts to a sump baffle. Also bought a 24V terminal for EB832 accessory ports. I can attach up to two bare wire accessories to the terminal and run them off one EB832 or one FMM port. And last of all a custom built cooling fan for the electronics crammed in the tight space in my Reefer cabinet. The thing looks like a Cadillac and is built with some top notch parts. It connects to my EB832 through a 24V port. Harry even included mounting screws and a drill bit for screw pilot holes. Can’t wait to get this thing mounted and try it out. I plan to control the temperature in the space using an Apex probe module with temp probe and the 24V port to switch the fan on and off.
