I have replaced an old Siemens temperature thermostat with the above. The Siemens unit just had two wires (connected to L and Y1) I connected these to the horseman unit on terminals 1 and 3.
Now when I turn on the heating it fires up even though - at the time - the room temperature showed 22 degrees and the target temperature at 18 degrees. I thought that in these circumstances the heating should not be on?
Three things:- when I override / increase the target temperature up to the ambient temperature there is an audible 'click' but all the time the heating is going; when I decrease it down past 5 degrees, there is a 'click' and target shows 30 !; but, if I take the unit from the base plate, the heating does stop.
Am I missing something here ?
regards
