Dwell/Feed Selector Switch
The water feeder has a DIP type switch block with
four on/off switches. Each switch has a specific
dwell/feed cycle which is activated upon receiving
a signal from the LWCO. The feeder will be deacti-
vated when the LWCO is satisfied or if the
dwell/feed period has been exceeded.
Manual Feed
There is a manual feed button which when pressed
will add water to the boiler.
Multi-Color LED
A multi-color LED indicates status during operation,
incorrect switch selection and when dwell/feed
cycle has been exceeded.
Dwell/Feed Cycle Limit
The feeder will stop feeding water whenever the
selected dwell/feed cycle time has been exceeded
and the LWCO is still sending a signal.
