Operation
FEATURES
Universal Compatibility-The VXT can
be used with virtually any probe or float
type low water cut-off.
Programmable Feed Delay-Helps
prevent flooded boilers by allowing
time for condensate to return to boiler
before initiating a feed cycle.
Programmable Feed Amount-Two
ways to feed; gallon amount settings
can feed above the probe to a working
water line. LWCO setting ends feed
when LWCO reenergizes the burner.
Underfeed Protection-If one feed
cycle is not enough to restore boiler
operation, the VXT will delay and feed
one additional time.
VXT Steam Boiler Water Feeders are primarily used on residential and light commercial
steam heating boilers up to 500,000 Net BTUH. They are not recommended for commercial
steam process work.
The VXT feeder should be wired to and receive its signal from a float or probe type low
water cut-off. When the VXT receives a signal from the LWCO, it initiates an adjustable
delay before feed to allow condensate from the system to return to the boiler and near boiler
piping. Upon completion of the delay, if the LWCO feed signal is still present, the feeder
begins its feed cycle. If the feed signal is still present after the completion of the feed cycle,
the control will revert back to its delay mode. After the second delay expires the control will
begin another feed cycle. If the signal is still present after the second feed cycle, the control
will lock-out until the feed signal from the LWCO has been removed. Once in lock-out, the
feeder can be forced to feed an additional two cycles each time power is removed then
reapplied.
Lock-Out Flood Protection-The
VXT will lock out to prevent system
flooding and costly water damage if
burner operation does not resume
after two consecutive feed cycles.

Digital Feed Counter-Displays the
amount of water added to the boiler -
essential in detecting boiler destroying
water loss problems.
