Restore factory settings:
The standard factory settings for the delay times can be
restored by setting switch 1 & 2 of the DIP switch to
‘ON’ (*4). If the voltage is switched on to the kit in this
state then LD2 (yellow) will flash. After that keep the
pushbutton pressed in until both LD1 and LD2 flash. The
standard times of 3 minutes are now again stored in
memory. Switch the voltage off and select an operating
mode using DIP switch SW1 (slow ON/OFF or step
mode).
