All A class models Error code 29
This error is terminal. Replace ACB, but talk to Gledhill as other parts are also required. Engineer only this one.

Re: All A class models Error code 29
Interesting!
Not sure I've ever encountered an Error Code 29.
My documentation says 29 is "WD Communication error". Can you expand on what this means please?
Thanks, MIke

wd comms error
This is only on an A class.
WD stands for watchdog (comms error)
On Electramate A class the system will lock out showing error 29. The error is external to the ACB but everything checks out fine. To fix contact spares and ask to speck to Chuck, He has a fix it kit of parts with a schedule of modifications to carryout. Only a handful have been done I understand. Basically you change it into a BMA fitting a white 1.5k resister and modify the way the ACB controls the power relays and the off peak sensing relay circuit and 3 port valve. Their engineer in Birmingham spent weeks trying to find the solution to this lockout problem.
