7.4 Viron eVo Pump speed selection
:
•
Enable System mode in the Viron Pump menu
–
refer to Viron Pump Instructions
•
Set Pump speeds as follows: Once the RJ12 Cable has connected the pump and eQ Chlorinator, change the
chlorinator mode to “Manual On” to en
able adjustment of the Pump Speeds. Note, once the pump is turned Manual
On, it will go into Priming Mode for 5 minutes before the speeds can be changed. Alternatively, set up the pump
speeds before the RJ12 connector is plugged into the chlorinator. Once the pumps speeds have been set up, ensure
the SYS (system) mode is enabled in the Viron Pump Menu.
•
In Ai Mode, the high speed should be set at near maximum speed of the pump.
•
Medium speed should be set at a speed where the chlorinator electrode cell fills with water during operation and the
skimmer box weir door creates some surface tension on nearby water to skim properly. Usually, this speed will be
between 1200 and 1600 RPM.
•
Low speed should be selected at 600 RPM. This speed will be referred to as sampling speed. Ensure water is flowing
through the chlorinator cell at this speed.
7.5 Operation in Ai Mode
.
When Ai Mode is selected the Viron e-Quilibrium will operate in the following manner:
•
The pump and electrode cell will start at the first time period. After the initial 5 minute priming period, the pump
will revert to filter speed (medium speed), the Viron e-Quilibrium will test pH and chlorine levels and both adjust the
chlorine production and dose acid to achieve the desired levels.
•
The Viron e-Quilibrium will ensure the pump operates until its primary two objectives are achieved: (1) the Water is
turned over 1.5 times (on a 50,000 litre pool, the pump will move 75,000 litres of water to ensure all of the water is
filtered) and (2) the chlorine level is achieved. In the winter, this may be only 4 to 6 hours of operation. In the
summer, when the pool is subject to high UV and heavy bather load it may be 12 hours as the chlorine level is
constantly under demand.
•
When both objectives are achieved, the Viron e-Quilibrium will turn the pump down to Sampling Speed (approx.600
RPM) which is almost inaudible and costs less than 0.5 cents per hour. During sampling speed the Viron e-Quilibrium
simply tests for chlorine levels. If the family all jump in the pool later at night and the chlorine is dissipated, the Viron
e-Quilibrium will turn the pump back to filter speed (medium) and turn
the electrode on to produce more chlorine.
Your family is protected even when swimming later at night as the system is filtering and sanitising the pool or spa
water automatically.
•
Finally, if the correct chlorine level is NOT achieved when the system shuts down at the end of the day on time clock,
it will start on maximum output and maximum pump speed the following morning until the chlorine level is achieved.
Once the chlorine level is achieved, the pump will revert back to the gentle filtration speed until the required number
of water turns and chlorine levels are maintained.
•
In Ai Mode you can select four timer periods. Each timer period can have a specific pump speed selected (high or
medium) or allow the Chlorinator to select the appropriate pump speed. Normally you will only select a specific
pump speed when you wish to operate a cleaner or water feature at a specific time every day. Low speed cannot
be selected in Ai Mode as low speed becomes the default “sampling speed” to allow the unit to continue to monitor
chemical levels while the Viron Pump is operating at a very low output.
