i have a HRV installed in my home and ok it does all the right things, but I want to stop it From starting on its own and give me control to start and stop as I want.
I dont want it starting at 4am in the morning after I have shut it off at night and blowing cold air in, until I am up dressed and ready for it to work.
Anyone got a wiring diagram as I want to install a separate switch to control it
