Admixture calibration for proportional valve
Given the heavy temperature fluctuations at the start of brewing cycle, the initial opening path of the proportional valve can be adjusted via the mixing calibra-
tion (=cold water mixing amount) as follows
Start beverage
First value displayed = target temperature configured in the recipe
Observe the max. and min temperature
With larger deviations, between the target and max/min
configure this difference temperature

lower.
Repeat the procedure until the temperature
has leveled out to +/- 2 °C.
Example for determining the temperature difference:
First value displayed
= target temperature configured in the recipe = 92°C
Max. temperature during beverage serving
= 98°C
Temperature diff6°C
Mixing calibration setting:
-6°C
