Remove trv cap, brass protrudes about 1mm, can press it down slightly, rad heats up when trv cap off, but when cap back on regardless of temp setting always cools down and goes cold. Should pin press down further, maybe till flush with base when cap temp low or switched off, or is the cap faulty, can anyone help?
