Long story short, I’ve recently discovered my house has underfloor heating, and seems to be controlled by a switch. But above this switch is the thermostat and when I turn the switch off, the thermostat turns off. I can turn the heating on via boiler without the thermostat being on, but I’m confused how I control the heating temp if the thermostat is off (I presume it’s off because when I turn the switch off, the red light turns off), any ideas? Recently moved into first home and finding boilers/ heating hard work
