Basically from what I can tell the wire I’m questioning also powers the pump. I believe by powering the yellow cable. I’ll take a video later to try and show the issue.
Yea that is correct. However the pump somehow also receives power off another what that is not directly wired to it. I assume this wire also powers the yellow wire. The wire I am referring to is seated next to the blue sleeved red how water on wire.
Correct however the pump also powers off the normal red wire sat next to the hot water wire (blue sleeved red). Which does not directly run to the pump so I am unsure how it is powering it.
I can’t tell as it dives into the flooring. It’s strange as the 3 wires from the pump (standard 3 core) non of them have any interaction with the wire powering the pump. The live is the brown at the far right.
I’m not sure I’m yet to check. The comm wire currently sits with the orange off the port and runs into a red. Do I presume this is the switch live?
I’m just confused as to why a wire that does not run directly to the pump somehow powers it indirectly once seated with the hot water on wire from...
The black wire which is comm sits within the wire with the orange. And the call for heat sits with the call for heat wire from the controller. The only way I receive heat is when the cylinder stat calls for heat which in turn fires the heating. The biggest issue I’m having is locating the...
I always believe the far right sleeved yellow was the switched live as the brown wire from the pump sits with it. However the secondary wire next to the blue (hot water call) powers the pump, however does not directly run to it.
Hive hot water and heating programmer and thermostat however old wiring is still in place and linked in hallway.

Hi all. Recently moved home and the wiring is a mess. The central heating only operates if the cylinder thermostat is low enough to send a call for heat. The system also has a satisfied which if I wire correctly sends the boiler into fault mode as obviously it is receiving 2 different messages...
