Notes:
1 - 24V Accessory relay (see SW2 - 3 for description of operation)
4 – SW2-8 must be in the OFF position for pulsed “L” lockout signal and in the ON position for constant
“L” lockout signal.
2 – This Switch allows the unit to down stage with the t-stat when OFF and finish on second stage when
ON.
