• No more trips to the basement to add water to the boiler
• Works with all probe and float type low water cut-offs
• Brightly illuminated feed counter displays the amount of water added to the boiler
• Built-in memory prevents power interruptions from clearing the counter
• Helps prevent flooded boilers, allows time for condensate to return to the boiler before starting a feed cycle
• Six settings provide two ways to feed
• 1 - 5 Gallon settings now feed above the probe to restore the boiler's normal operating level or select LWCO setting to end the feed cycle
• Allows for additional make-up water at the touch of a button, manual feed amounts are recorded and added to the totalGallons displayed by the feed counter
• If one feed cycle is not sufficient to restore boiler operation, the VxT will delay and feed one additional cycle
• Digital feed counter
• 30 sec to 10 min programmable feed delay settings
• LWCO and 1 - 5 Gallon programmable feed amount settings
• Manual feed button
• Underfeed protection
• Lock-out flood protection
• 1 gpm flow rate
• 10 VA power consumption
