MiniWarden Manual 530-487-5007 21
O If RLY On -none: The default setting is none or disabled. This feature prevents 2 relays being on
at the same time. It means this ORP Relay will be O if the pH relay is On. This is useful in cases
where the chemical injection points are very close together and prevents the ORP relay injecting at the
same time the pH relay is injecting. Simply press Enter to toggle between none and pH.
O if Flow O - 1: The ORP Relay will be turned o if “No Flow” is detected in Flow Switch Input 1.
Note: This setting can’t be changed as it relates to safety, pressing the Right Arrow to change has no
eect.
SetOvrfeed 00:00:00: This type of overfeed requires the measurement to approach the setpoint. If a
feed tube is broken and the chemicals are going on the oor this type of overfeed protection will detect
that and shut down the relay sooner than the daily overfeed. Calculate how much feed time is required
for the setpoint to be reached when the sanitizer is at 0. When the Setpoint Overfeed is reached the
relay status will display an “s”. The default value is 00:00:00 which is disabled, in order to use this
feature calculate the amount of time required and enter that time.
❑ When in Setpoint Overfeed, there are only 2 ways to reset it: 1) cycle power on the MiniWarden an
d 2) Manually x the chemical imbalance so that the setpoint is approached within 5%.
❑ When feeding sanitizer the ORP measurement will rise as sanitizer is being added. When the ORP
is within 5% of the setpoint the Setpoint Overfeed timer will clear.
❑ If it would take 2 gallons of liquid chlorine to raise the chlorine level from 0 to the desired value,
calculate how much time that would be, and enter the time. This time should be quite a bit lower
than the 24 hour Overfeed timer.
Overfeed 06:00:00: All chemical feed relays include this overfeed feature. The Overfeed time
represents the maximum amount of time a chemical relay will feed in a day from midnight to midnight.
This must be set up properly to reduce the chance of feeding large amounts of chemicals in the event
something goes wrong. The default time will most likely not be correct. Please follow the calculation
below. The minimum value for Overfeed time is 1 minute, it can’t be disabled.
❑ Calculate the total amount of chemical the pool would ever need in a 24 hour period. (Example: 10
Gallons would be the MOST liquid chlorine a pool would need on any given day).
❑ Calculate the amount of time it would take the feed-
pump to inject that total amount of liquid chlorine
in a 24 hour period. Example: Limit to 10 gallons with a 50 Gallon Per Day (GPD) Fixed Rate
Peristaltic Pump. 10 Gallons / 50 Gallons * 24 Hours = 4.8 hours or 04:48:00. You will need to
adjust for variable pumps depending on the variable pump setting. Most variable pumps use a
scale of 10 to 0. So if the pump is set on 8 then use 80% of the total GDP rate, in this case .80 x 50
GPD = 40 GPD.
❑ Calculate the overfeed time with the following equation using the following example…..
Overfeed Time = (Daily Gallon Maximum) / (Pump GPD Rate) times (24 Hours)
Round up and set the overfeed time. It can be set for minutes and seconds for ner control.
