Good evening. Recently i have installed Dual Channel Hive V3 thermostat replacing old Drayton LP241. I looked on the forums and that supposed to be straight swap.
However, i have problem. At the moment when i will put hot water on, radiators get hot. Heating can be disabled but radiators will still get hot.
I have tracked the problem to probability of faulty motorized valve or its head which will be replaced. Changing temperature down on the programmer will not stop the heating.
Another thing is wiring. There was wireless thing with the room programmer connected to Drayton which i have removed and disconnected the wires from the Drayton mounting plate. Disconnected doubled live and neutral and the left over wire i have connected to terminal labeled 4 in Drayton mounting plate which i assume is Central heating on. Is that correct place for this wire?
Setup is:
Worcester Greenstar 18Ri Erp boiler with hot water tank
3 way Drayton motorised valve
Hive V3 Dual channel thermostat
I know that motorized head was replaced before and was not connected by the professional. Is it only 4 wires supposed to be going to drayton mounting plate or all 6? HW off NC and CH off NC on the plate dont have any wires connected. Unfortunately at the moment i don't have photo of junction box wiring.
Also i know that before fault heating could work only when hot water was on, is that problem with wiring or with valve position? On Which position valve should be set to get heating without hot water on? H M or W ?
Please help.
