I have a Biasi combi boiler and a Hive 2 unit (I think), I have wired it up according to other forums Live and Neutral in the first 2 ports, then the thermostat wires in 1 (common) and 3 (boiler off). I'll upload a picture to show what I mean. when I press the central heating button on the hive receiver the boiler doesn't switch on, but when I turn on the hot water nothing happens, when I turn off the hot water button the boiler switches on, pushing the hot water button again (on) the boiler switches off...... I don't get it at all. Can anyone help?
