This is the panel mount controller used in all our residential DX2W modules. You will need to specify in your order comments whether you have the first generation 36"x24"x14" coax heat exchanger module or the second generation 24"x24"x14" tube-in-shell heat exchanger module since they have different I/O configurations and software versions. If your system used a tank heater or has floor or panel cooling options or was customized in any way you will need to specify the name of the original customer so we can lookup the software revision used and burn it onto the new controller before shipping it to you. https://thermatlantic.com/dx2w....-panel-mount-control

We now stock competitively priced PEX-AL Oxygen Barrier (OB) tubing in 1/2" ID in 300 M (985') long rolls to be used with our XPS-AL panels. One roll should be sufficient for four 120 SF bundles of panels. Although PEX-B has become the most popular tubing in North America for radiant heating applications, this is largely due to its lower cost compared to the other two types available. https://thermatlantic.com/pex-....al-tubing-1-2-id-x-3
