I recently solved a problem with the DHW on this boiler, with the help of some members here.
In doing so, I replaced the diverter valve, pressure sensor and eventually the main board.
It turned out that the replacement pressure sensor was also faulty. Problem solved. Great hot water.
As soon as I had finished, the central heating target temperature D.005 is constantly at 40C.
I replaced one of the temperature sensors but have the same problem.
I can post all of the D code readings if necessary (I've written them on the manual pages).
There is a simple remote relay thermostat.
TIA
UPDATE: D.005 target temperature is now 18C.
