Water Feeder – Residential
Model VXT-24 and VXT-120
•
Universal Compatibility
• Works with all major probe and float-type low
water cut-offs.
•
Digital Feed Counter
• Continually tracks and displays the amount of
make-up water fed into the boiler – essential for
diagnosing system leaks
that can severely shorten
the life of the boiler.
•
Call-For-Feed Indicator
• Illuminates during feed signal from the LWCO
•
Programmable Feed Delay Settings (30 Sec. to 10 Min)
• Helps prevent flooded boilers. Allows time for condensate to return to boiler before
initiating feed cycle – ensuring that additional water is needed.
•
Programmable Feed Amount Settings (LWCO and 1-5 Gal)
• With the LWCO setting selected, the VXT raises the water level to low water
cut-off. The 1 to 5 Gallon settings can be selected to fine-tune the VXT to restore the
normal operating water level above the low water cut-off.
•
Manual Feed Button
• Allows for manual feeds with the touch of a button.
•
Underfeed Protection
• If one feed cycle is not sufficient to restore boiler
operation, the VXT will delay and feed one additional cycle.
•
Lock-Out Flood Protection
• Locks-out after two consecutive feed cycles
to prevent flooding.
MODEL VOLTAGE DESCRIPTION/OPERATION
VXT-24 24 VAC Upon a feed signal from low water cut-off, the VXT feeder delays (from
VXT-120 120 VAC 30 seconds to 10 minutes) to allow condensate to return to boiler. If make-up
water is required after the delay period, the VXT will initiate a feed cycle. The
VXT can be set to feed to the level of the low water cut-off or can be set from 1
to 5 gallons to raise the water level above the cut-off to the normal operating
level. The digital feed counter tracks all water fed into the boiler including water
added using the Manual Feed Button.
