Honeywell ST699
Honeywell ST699
I have recently moved into a house with a very old honeywell control panel, st699 or st799, everytime i set the clock for the automatic timer it resets to 00:00 after a few hours, have looked into fitting a replacement, the ST9400c, is this a strwight forward job? Im confident enpugh with wires just not sure if they go in the same place on the replacement, thank you
