    Ideal Logic +18, intermittent fault

    Have an Ideal Logic + 18 with intermittent fault. When on demand the display constantly changes from O to C but burner doesn’t start. Can fix by switching Off then On again, but this only lasts for a day or two. As it’s an intermittent fault I’m reluctant to call out an Engineer. Any ideas?

    Hey guys. What’s the easiest way of determining that a 2 port motor has failed? I know that if the stat is calling and the arm is set to open on the valve and the actuator is ok it will fire. Is it purely a case of checking whether 240v is at the brown and orange when heat is called for? Any...
