These field settings are accessible and programmable through the

[5] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
The default setting is high speed (I). If the water flow in the system is
too high (e.g., noise of running water in the installation) the speed
can be set to low speed (II).
A list of all field settings and default values is given under "Field
settings table" on page 35. In this same list, we provided for 2

Procedure
The available external static pressure (ESP, expressed in psi (kPa)) in

water flow ((gallons/min) (l/min)) is shown in the graph
To change one or more field settings, proceed as follows.
Temperature values displayed on the digital controller
(user interface) are in °C.
Temperature values in °C are between brackets.
Conversion from °C to °F is for information only.
