VI. Controller functions – Fitter’s menu
Fitter’s menu should be accessed by a qualified person It is intended for adjusting additional
functions of the controller, such as the CH boiler parameters, the additional valves, the additional
pumps etc. It also enables the user to access advanced settings of the basic functions (e.g.
parameters of the built-in valves).
A simplified block diagram of the fitter’s menu is presented below:
VI.a) Valve settings
ST-979 controller has a built-in module controlling the mixing valve. It is possible to connect two
additional modules for controlling valves (e.g. ST-431N). There is a range of parameters allowing
the user to adjust the valve operation to individual needs. Once a given valve is activated, the
display shows an additional menu offering a range of valve parameters to be configured.
Both the built-in valve parameters and additional valve parameters are similar, as illustrated by
the following block diagrams:
