forth from 699 and 700. It means that the relay will not turn on unless the condition of “On If ORP < 700” is
satisfied for at least 20 seconds - then the relay will turn on for the programmed “On Time 00:01:00” in this
case 1 minute. To change the on delay time, simply press
Enter
and change the time and press
Enter
again to save the new setting. Enter 00:00:00 to disable.
⧫
On Time 00:01:00:
This is the total amount of time the relay will be ON if the “On If ORP < 700” condition
has been satisfied. The default setting is 1 Minute. This command works in conjunction with the
MinTimeOff Command below. If the ORP reading is not being maintained then more or less on time may
be needed.
⧫
MinTimeOff 00:07:00:
This is the total amount the relay will be OFF if the “On if ORP < 700” condition has
been satisfied. This is the amount of time allowed for chemical mixing in the pool and works in conjunction
with the “On Time” Command above. Do not set to 00:00:00 if the On Time is not also set to 00:00:00 as
they work together.
⧫
Off 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 Off 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 through the selections.
⧫
Off if Flow Off - 1 or 3:
The ORP Relay will be turned off if “No Flow” is detected in Flow Switch Input 1
for Pool1 and if “No Flow” is detected in Flow Switch Input 3 for Pool2.
Note
: This setting can’t be changed
as it relates to safety, pressing the
Right Arrow
to change has no effect.
⧫
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 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 PoolWarden and 2)
Manually fix 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 finer control.
