Boiler only comes on when heating is on but not when only hot water is on
Hi,
I have a strange issue where the boiler only fires when I turn on the central heating, this turns on both the central heating and hot water.
Turning just the hot water on, it show in Tado receiver that the hot water is on but the boiler doesn't fire. I believe I have a S plan and the 3rd and 4th pictures are of the honeywell thermostat and me decomissioning it (not sure I've done it correctly)...
