My 824 has suddenly started indicating the system pressure on the digital indicator instead of the running temperature which it has done for the last 18 months.
I've tried resetting, turning off the power, etc, but it reverts to pressure after running thru it's start up sequence.
The boiler seems to run OK on both CH and HW and the Pressure gauge matches the digital pressure but why has it changed? Is this a control fault/card problem on the horizon?
