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
connection. If ground is needed, it must be connected to
the main ground terminal.
2) Prog. output 3: (alarm relay); this is a triac output with an
active voltage of 120 VAC, it can only handle resistive
loads between 5 and 50 Watt.
