Just moved home and went to put heating on and it's showing error code f15 on my Honeywell thermostat. I've googled the manual and it states Remove plug in hW socket and connect to correct socket however I haven't a clue what a hw socket is or where I find it? Any ideas anyone?e

If it is the Smartfit Y Plan it means there is something plugged in to the HW valve socket which should not be used. You should remove the plug and put it in the correct socket (in the base unit).
This would normally be found on commisioning the system though.
