easy way to do it is to open the panel,swap zone one for zone 4 that is remove the wires from zone one fit them on zone 4 and vice versa,but,you need to make sure there is not a beam between you and the keypad
to change time,press prog,all leds flashing,then key in 9999.press 1,zones 123 leds should be lit,input a new exit time,eg,for 20 seconds input 020 this is the exit time,for entry time press 2 then leds 123 should be lit,key in 020 -20 seconds,to exit engin prog press reset twice or if you can get the engin maual you can reprog the zones without disscon the wires
