This is the situation . Hopefully the pictures show the connections you need to figure out . the temperature on the thermostat is 22,7 , the same at the weather station .

Hello,
Thank you for your concerns...
I understand what have to be done on your boiler: find exactly on which ports the two control wires are connected. I think that it's on ports A and B, or LZ and NZ.
When you are sure, just disconnect them, then, remove the bridge of LS-LR ports (just beside the main power supply wires), and connect the control wires on these ports.
Finally, connect the Thermostat on these control wires and everything should be fine.

Hi,
There is no polarity on control wires, you can connect them without taking care of the order.
