Buzzing sound from wireless receiver

edited November 22 in Technical Questions
Hi all,

when I switch on the heating with the app my wireless receiver makes a buzzing noise for a few seconds before it switches on. We had a boiler repair man in the other day because the boiler wasn’t responding properly and he thought it was strange.


  • Boiler is not responding to the call for heat but does when I switch on the hot water. When it’s just the heating the wireless receiver will intermittently make the buzzing sound so I’m thinking it might be something electrical fault. That is strange though because it worked fine for the first 2 weeks after we bought it.
