Hi, woke up this morning to my heating not on, checked the Thetmastat and it said H152 error, I've done nothing but Google search and YouTube videos for guidance but it's still not working. If I take the thermostat of tge base and plug it in it tells me to place back on the base, Ince uve done this a message shows saying thermostat needs to shut down to allow battery to charge... we've left it hours and tried again but we then get the H152 error again. there is nothing wrong with the cables connectors plug sockets fuses ect we've checked everything.. please help im at a loss.
