• UNIVERSAL COMPATIBILITY: The VXT feeder can be used with virtually
any probe or float-type low water cut-off.
• FEED COUNTER: Brightly illuminated feed cycle counter displays the
amount of water added to the boiler – essential in diagnosing water loss
problems that can severely shorten the life of a steam boiler. Built-in mem-
ory prevents power interruptions from clearing the counter.
• PROGRAMMABLE FEED DELAY SETTINGS: Helps prevent flooded boilers.
Allows time for condensate to return to the boiler before starting feed
cycle – ensuring that additional water is needed.
• PROGRAMMABLE FEED AMOUNT SETTINGS: Six settings provide two
ways to feed: 1-5 gallon settings feed
above the Low Water Cut-Off to
restore boiler’s normal operating level. Or, select LWCO setting to end the
feed cycle when the Low Water Cut-Off re-energizes the burner.
• UNDERFEED PROTECTION: If one feed cycle is not sufficient to restore
boiler operation, the VXT will delay and feed one additional cycle.
• LOCKOUT FLOOD PROTECTION: The VXT locks-out to prevent steam sys-
tem flooding and costly water damage if burner operation does not
resume after two consecutive feed cycles.
