Just fitted a Honeywell G4 panel, all is working fine apart from a strange set bug. I've set it so program 2 is the night program, this program is set to 30 seconds set time in silent mode. Sometimes when I set prog 2 (either by code or fast set button then P2) it does the beeps for the time delay. If I enter the code then set it again it is always silent the second time! Is there a known software bug or have I got something wrong with the programming? Thanks
