Timing Mode:
Timing cycle begins upon application of power to the heater terminals. At the end of the
initial delay time the relay contacts transfer and remain in a transferred state until input
power is removed. When the heater input power is removed, the contacts transfer back to
their original state at the end of a reset (release) delay period.
