Just had a new combi boiler fitted for heating & HW. Plumber supplied a wireless (battery-powered) Salus RT520TX thermostat / controller.
The wireless stat is emitting a very high-pitched electrical-type whining noise (a bit like you hear from a plugged-in phone charger when no phone is connected) every time the LCD display is lit.
I also accidentally entered the "test" menu and had it run through that cycle (whatever that does!), and the noise was even more apparent.
Has anyone else experienced this noise with a Salus or other wireless stat? Should I be worried?
