The pressure and temperature relief valve PTR is designed to relieve the increase in pressure caused by water expansion during the normal heating cycle. The PTR valve will then relieve the increase in pressure by releasing drips of hot water to the drain line. Should the electrical temperature cut-out device cease to operate correctly, the water will overheat. The temperature probe will then open the PTR valve and discharge hot water to the drain line.
