A clicking sound from Tado Wired Thermostat
Hi I used a Tado wired Add-on Thermostat replaced my old classic wired thermostat for my 2nd floor bedroom. It work fine. But tonight I can hear a quite obvious clicking sound/noise while the Tado Thermomstat is on or off the heating. I am not sure it’s normal or not. But my Tado wired start-kits which installed downstairs didn’t make the clicking sound while it’s on or off. So strange. Anyone heard this sound please? Thanks!
