I just changed an ancient programmer and room stat for a Sunvic 207XL programmer and Sunvic TLX9000 stat. Two channel's set up for 24 hour programme.
It all works fine, except when you turn the water on - then the Programmer slowly gets hot on the top middle and the LCD display starts the develop a growing black patch. Its ok when the CH is running, it only occurs when you turn the water on.
If you turn the water off, the black patch clears and its ok.
Now, what it suggests is the wiring to the immersion heater or the terminal in the programmer is heating up. It doesnt feel like its gettign warm, its worked fine on a mechanical timer for years.
Am i missing something here? Are you not supposed to run an immersion heater through these terminals? if not, what is the HW switched output designed to operate?
