Main dosing
The main dosing takes place on a specific day of the week, the so-called main dosing day. The amount of Bayrosoft
®
that is dosed
corresponds to the programmed dose amount. Depending on the measured water temperature, the actual dosed amount may be
increased by a certain factor. This mechanism is referred to as temperature compensation. The dose amount is corrected to
compensate for the increasing attrition of the care product at higher temperatures.
The factor by which the programmed dose amount is increased is shown in the following table:

For water temperatures below 24 °C, there is no temperature compensation.
For water temperatures above 32 °C, double the programmed dose amount is added.
Example:
For a programmed dose amount of 2.0 litres at a water temperature of 28 °C:
Main dose amount = 2.0 litres x factor 1.20 = 2.40 litres
Main dosing takes place on the programmed day of the week at midnight. If the flow signal is missing (e.g. because circulation has
been switched off) or if there are alarms, main dosing will be delayed.
11.5
Intermediate dosing
In the course of the week that passes until the next main dosing, the amount of effective Bayrol in the water will decrease steadily.
Product attrition accelerates at higher temperatures. To compensate these effects and to ensure that the optimal amount of Bayrol is
always in the water, intermediate dosing takes place after the first third and the second third of the week.
The dose amount of the intermediate dosings depends on the following factors:
Programmed dose amount
Measured water temperature (for the preceding third of the week)
Temperature compensation setting (off / normal / high)
If temperature compensation is switched off, intermediate dosing does not take place.
If temperature compensation is switched on, the dose amount of the intermediate dosing is calculated by multiplying the programmed
dose amount by a temperature-dependent factor.

At temperatures below 24 °C, intermediate dosing does not take place (factor = 0).
Example:
For a programmed dose amount of 2.0 litres, the actual dose amount at a water temperature of 28 °C and the "Normal" temperature
compensation is:
Intermediate dose amount = 2.0 litres x factor 0.2 = 0.4 litres
For the "High" temperature compensation setting, the actual dose amount is:
Intermediate dose amount = 2.0 litres x factor 0.4 = 0.8 litres
The first intermediate dose takes place two days after the programmed dosing day at 8:00 a.m.
The second intermediate dose takes place four days after the programmed dosing day at 4:00 p.m.
If the flow signal is missing (e.g. because circulation has been switched off) or if there are alarms, intermediate dosings will be delayed.
