The LP112 is wired with two wires in the live neutrals, 2 wires in live terminal and one wire in the water on (3) and heating on (4). No wires in the off terminal. There is a hard wired Boss BRTmk2 room thermostat. I have replaced the LP112 with a Hive 2 receiver and disconnected the room thermostat and insulated each of the wires separately. I have good communication between the Hive hub , the receiver and the hive thermostat. The green lights show that the hot and water heating circuits come on when triggered from the wireless thermostat BUT there is no trigger to the boiler and the system is not working. I have replaced the original LP112 controller and Boss thermostat and all is working fine again. What am I doing wrong. The wiring is not what I expected but I have not changed anything. Is the problem associated with the wiring out of the thermostat and therefore not completing the circuits. Thank you for any help you may provide.

The feed and switch wires from the origional thermostat need to be connected together not isolated.
