Yeah, I started second guessing myself and was getting worried something might go bang .
How can I be sure it's doing something?
heating/plumbing stuff is one of my "weak" spots where I lack knowledge. I can barely make out the flow meter things so can never tell what's happening anyways :-/
Hi There,
I currently have an unbranded "ZL-2061-01" fitted: https://theunderfloorheatingsite.co.uk/shop/thermostats-controls/water-underfloor-heating-thermostats/water-underfloor-heating-thermostat-programmable-3-amp-room-stat-with-air-sensor-in-white/
It has 3 wires
I'm replacing this...
