Dear All, moved into an old house last year and one room is heated by electric Ufh which doesn’t work, it’s a large room about 25sq m and uses a devireg 550 wired through a contactor I assume due to the large load? I have tested the heating cable (we have some paperwork to suggest it is devi cable fitted) and the resistance is coming out at around 15 ohms but if i bypass the thermostat and wire direct thru the contactor it simply trips the main circuit board. Do you think it’s knackered or should I be testing anything else?
