The Electric Water Feeder, is an electronics based water feeder for steam boilers. The EWF monitors the output from a Low Water Cutoff. When the LWCO detects a low water condition, it signals the EWF, which initiates a water-feed cycle. Since the EWF is fully programmable, it can feed as long as the low water cutoff detects a low water condition or fixed feed amounts. In addition, the EWF allows the user to set Delays Before Feeding, or hold delays after the low water cutoff signals water is restored. The EWF also includes a programmable excess feed indicator. The EWF blinks this LED after it has fed more than a settable number of gallons into the boiler over the past 30 days. This will help identify systems that may need maintenance.
- LWCO Mode: As soon as the Electric Water Feeder receives a low water signal from the LWCO, the EWF starts feeding water to the boiler after the Delay Before Feed expires, if enabled. The EWF continues to feed water to the boiler until the LWCO signals that the water condition is normal and any Hold After Water OK delay settings expire. If the EWF feeds more then 10 gallons, Flood Protection Lockout Occurs and feeding stops immediately and a red LED is illuminated.
- Fixed Feed Mode: When the Electric Water Feeder receives a low water signal from the LWCO, the EWF will feed the number of gallons set by the DIP switches on the control (1, 2, 3, 4, or 5 gallons). Feeding will start after any Delay Before Feed setting expires. After a feed cycle completes, if the LWCO still signals a low water condition, the EWF will start another feed cycle. If the EWF completes the second feed cycle and the LWCO still signals a low water condition, the EWF will enter the Flood Protection Lockout and a red LED is illuminated. Pressing and holding the Manual Feed button for 2 seconds will reset the Flood Protection Lockout.
- Manual Feed: By pressing the Manual Feed button, the user can feed water to the boiler system. Up to 5 gallons may be manually fed continuously before the EWF automatically closes the feed valve. Water fed manually counts toward the Excess Feed setting.
- Excess Feed: The Excess Feed LED will rapidly blink amber when the EWF has dispensed more water over the past 30 days than the setting of the Excess Feed switch (6, 8, 10, 12, 15 gallons). Unlike other controls where power needs to be removed and reconnected to the control, the Taco EWF has an internal reset button. There is also no need to check, record and reset the feed counter just to determine if too much water has been added. The external LED provides a simple and fast means to determine that the boiler system is consuming excessive amounts of water, so service personnel can repair the piping or boiler before the system sustains more damage or further corrosion.
- Hold After Water OK: The Hold After Water OK delay permits the water level to rise above the level of the LWCO probe or float mechanism and provides additional water into the system. This prevents intermittent low water conditions and resulting short cycling of the boiler during calls for heat. Short cycling reduces the boiler’s life expectancy and unnecessarily stresses the system.
