Automatic dosage O2 (BayroSoft)
INFO
This section applies for the model

O2 only.
13.1
Basic concept
Adding the optimal volume of BayroSoft into the swimming pool water
is executed in multiple automatic dosages per week. The main dosage
is performed on a specific chosen weekday, which provides for a high
BayroSoft concentration and therefore for optimal disinfection. Then
additional interim dosages are performed throughout the course of a
week as needed in order to maintain the oxygen level continuously
over the requisite minimum value that ensures safe and reliable
disinfection.
The volumes for the main dosage and the interim dosages are
automatically adjusted to the average pool temperature in order to
compensate for heavier product attrition at higher temperatures. This
function is called temperature compensation.
The recommended setting for the basic dosage volume is 0.5 litres per
10m³ of pool volume.
13.1.1
Main dosage
The main dosage is performed on a specific weekday, the main
dosage day. The volume of BayroSoft dosed on that day is based on
the programmed basic dose volume. However, depending on the
water temperature measured, the actual dose amount may be
increased by a certain factor. This mechanism is called temperature
compensation. The dose amount is corrected such that the increasing
product consumption that occurs with increasing temperature is
compensated.
The factor used to increase the programmed dose amount is yielded in
the following table:
Average temperature value from the previous week
≤
24°C 25°C 26°C 27°C 28°C 29°C 30°C 31°C 32°C >32°C
Factor
1.00
1.06 1.10 1.15 1.20 1.28 1.40 1.57 1.80
2.00
No temperature compensation is performed for water temperatures
under 24°C.
For water temperatures over 32°C, double the programmed dose
amount is added.
Example:
For a programmed dose amount of 2.0 litres and water temperature at
28°C:
Main dose amount = 2.0 litres x factor of 1.20 = 2.40 litres
The main dosage is performed on the programmed dosage weekday
at midnight.
If the flow signal is missing (e.g. due to circulation being turned off) or
if there is an alarm, then main dosage will be delayed. It will be
performed at the earliest point in time. It is not until the next main
dosage day that the previous main dosage is discarded if it could not
be performed up until that point.
13.1.2
Refresh dosages
Throughout the course of a week until the next main dosage, the
volume of effective BayroSoft in the water diminishes. Product
consumption increases with higher temperatures. To counteract this
and to always guarantee the optimum volume of BayroSoft in the
water, refresh dosage is performed at the one-third and two-third
points in the week (1/3 week = 56 hours = 2 days and 8 hours).
The refresh dosage amount depends on the following factors:
•
Programmed dose amount
•
Average water temperature measured
(for the prior 1/3 week)
•
Temperature compensation
setting (off / normal / high)
When temperature compensation is turned off, no refresh dosages are
performed.
When temperature compensation is turned on, the refresh dosage
amount is yielded by multiplying the programmed dose amount by a
temperature-dependent factor:
Average temperature value from the prior 1/3 week
≤
24°C 24-26°C 26-28°C 28-30°C > 30°C

For temperatures under 24°C, refresh dosage is not performed
(factor = 0)
Example:
For a programmed dose amount of 2.0 litres and water temperature at
28°C, the "normal" temperature compensation setting is yielded.
•
Refresh dose amount = 2.0 litres x factor of 0.2 = 0.4 litres
Thus, the "high" temperature compensation setting yields the
following:
•
Refresh dose amount = 2.0 litres x factor of 0.4 = 0.8 litres
The 1st refresh dosage is performed two days after the programmed
dosage weekday at 8:00 a.m.
The 2nd refresh dosage is performed four days after the programmed
dosage weekday at 4:00 p.m.
If there is no flow signal (e.g. due to circulation being turned off) or if
there is an alarm, then the refresh dosages will be delayed. They will
definitely be performed at the earliest point in time.
It is not until the next main dosage day that a refresh dosage is
discarded if it could not be performed up until that point.
Example:
If the dosage day is set to "Friday," then the following times are
yielded:
Main dosage, Friday at midnight
1st refresh dosage, Sunday at 8:00 a.m.
2nd refresh dosage, Tuesday at 4:00 p.m.
