The boiler manual states: If a room thermostat is to be connected to a time switch the wire between the time switch "on" terminal and boiler terminal 4 should be broken by the contacts of the room thermostat.
I have taken a look at the wiring for the CH On on the LP522 and that terminates to 9, its the yellow taped wire in the photo.
Would I remove the yellow taped wire (CH ON) from the LWC3 and connect it to the Common on the thermostat. Then the neutral to the terminal 5 on the boiler. Then the call for heat to the terminal I removed the yellow taped wire from?
