Hi, I’ve got a baxi 28he platinum in a rental property. Its got an old back rf timer/thermostat that not longer works correctly so the heating has a mind of its own. I’m looking to replace it with a hive (or similar) but I’m unsure if it’ll be compatible. Any suggestions or help would be good. I’m guessing it’s just a case of wiring the power through the controller part of the hive then into the boiler.
