NOTICE
Remarks:
1) Prog. output 2: (ext. igniter); this is a separate connector,
the pin in the middle is for ionization, it has no PE connec-
tion. If earth is needed, it must be connected to the main
earth terminal.
2) Prog. output 3: (alarm relay); this is a triac output with an ac-
tive voltage of 120 VAC, it can only handle resistive loads
between 5 and 50 Watt.
