My neighbour's immersion heater has stopped working. It appears to have 2 Sunvic thermostats - a VKL 2201 and a VKL 2251. There is power getting to the live terminal of the 2201, but the wire linking it to the 2251 seems to be dead. I presume from this that the 2201 is faulty; if so is it OK to replace it with a generic 7" thermostat from B&Q, or does it need to be another 2201 ? The immerser itself is a Howden WE501. I can't see any obvious reset buttons.
Thanks
John
