Chemical Setup (continued)
After you have activated both the pH and ORP Sensors the
Oasis SmartChem
will display this.
•
You will be able to adjust the pH Offset. The Offset allows you to adjust the
reading of the probe. Your probe may be reading pH at 7.7, but after proper
testing of your pool water the actual reading may be 7.6. You would then
adjust the Offset to -0.1.
•
The reading in brackets below the Offset is your current pH reading.
•
The pH Set Point is the level of pH that you would like your Pool/Spa
system to be running at. You can either tap along the line anywhere or tap
and drag to adjust the Set Point to where you would like it to be.
•
You will also need to tap the button beside Acid Dosing to activate/de-
activate the Acid Dosing Pump attached to the side of the
Oasis
SmartChem
controller.
•
The Acid Dosing button will generally be left On. The only time you might
turn it off would be if there is a problem with the pump, you are changing
over the acid bottle/tub or if you have run out of Acid.
The same functionality applies to the ORP Sensor.
•
The Offset will allow you to adjust the reading of the probe either higher or
lower. This will in turn effect when chlorination is called for, either delaying
chlorination or increasing its frequency.
•
The reading in the brackets is your current ORP reading.
•
You will tap and or slide the Set Point to set what Level of ORP you would like your system to run
too.
•
When the Probe Settle Time is turned on, no dosing is done for the first 30 minutes after the
circulation pump is turned on. If it is turned Off, dosing will commence as soon as the pump starts.
Notes:
• Acid is only dosed when the pH reading is higher than the pH Set Point. If the pH reading is above
8.5 then acid will not be dosed. You will need to manually add acid.
• The pH Offset will only allow adjustment of up +1.5 or -1.5 points.
• Chlorine is added/dosed only when the ORP reading is below the ORP Set Point. If the reading is
below 300mV then Chlorine won’t be dosed, and you will need to manually add chlorine.
• The ORP Offset will only allow an adjustment of +150mV to -150mV.
