•If the LWCO signals a normal water
condition while the EWF is feeding a fixed
amount, the EWF will NOT stop feeding
until the number of gallons set at DIP
switch S3 has been fed to the boiler. Be
sure S3 is set to feed the correct amount
of water.
•Flooding or property damage may result.
Manual Feed
The Manual Feed button on the EWF allows the user to
manually feed water to the boiler system as long as the user
presses the button. Up to 5 gallons may be manually fed
continuously before the EWF automatically closes the feed
valve. If the EWF automatically closes the feed valve, the
Manual Feed button must be released and re-pressed to
manually feed more water. Manually fed water counts
towards Excess Feed settings.
Excess Feed Indication
The Feed/Status Indicator will be rapidly blinking amber
when the EWF has dispensed more water over the past 30
days than the setting of the Excess Feed switch (S4).
Pressing and holding switch S5 will reset the Excess Feed
Condition. See Fig. 2 for location of Excess Feed Reset
Button. Once this reset button is pressed and held for 2
seconds the EWF briefly turns off the Feed/Status Indicator
indicating reset has occurred. Once the EWF completes the
CONTROL UNIT OUTLINE DRAWING
FIG. 1
reset process, the Feed/Status Indicator will resume its
normal state. Once the EWF is installed and the system is
filled with water, reset the Excess Feed Condition to start
normal operation of the system.
Flood Protection Lockout
If the EWF dispenses 10 gallons in LWCO mode or
completes two feed cycles in Fixed Feed mode, without the
LWCO signaling a normal water level, the EWF enters Flood
Protection Lockout. In this condition the EWF shuts off its
feed valve, illuminates the Feed/Status Indicator LED to red,
and waits for the user to correct the problems and reset the
EWF. Entering the Flood Protection Lockout prevents
flooding the boiler in the event that water is not actually
needed by the boiler. Pressing and holding the Manual Feed
button for 2 seconds will reset the Flood Protection Lockout
condition. See Fig. 2 for location of the Manual Feed button. If
the EWF enters Flood Protection Lockout, the user must
trouble-shoot the system and correct the cause of the
condition.
Feed/Status Indicator
