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 floor 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 pH is a full point off. 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 fix the chemical imbalance so that the setpoint is approached within 5%.
❑
When feeding acid the pH measurement will lower as acid is being added. When the pH is within
5% of the setpoint the Setpoint Overfeed timer will clear.
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.
❑
Calculate the total amount of chemical the pool would ever need in a 24 hour period. (Example: 1
Gallons would be the MOST chemical 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 chemical in a
24 hour period.
Example
: Limit to 1 gallon with a 10 Gallon Per Day (GPD) Fixed Rate Peristaltic
Pump. 1 Gallons / 10 Gallons * 24 Hours = 2.4 hours or 02:24:00. 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 10 GPD = 8
GPD.
❑
Calculate the overfeed time with the following equation using the following example…..
Overfeed Time = (Daily Gallon Need) / (Pump GPD Rate) times (24 Hours)
Round up and set the overfeed time. It can be set for minutes and seconds for finer control.
Alarm Programming
In the “Relay Setup” menu are also the configuration settings for the
alarm light on the MiniWarden enclosure lid. In the Relay Setup Menu
simply scroll down to the Alarm and press
Enter
