10.2 Heat Circuit Functions
This section describes the parameters that can be set up for a heat circuit via the
service menus.
This picture is the service menu for a heat circuit. Heat
circuit functions are divided into 4 groups correspond-
ing to the menu items: Building, Pump/valve, PI con-
stants and Limiter. See the overview diagram on page
38.
Each menu item gives access to a number of setting pictures allowing you to view and
modify various parameters for the heat circuit. The number of pictures and parameters
available depends on the type of controller you are working with and the application
you have selected (see page 26 for information about ECL 2000 applications).
This section describes all parameters that can be set for a heat circuit. Please disregard
the descriptions of any parameters not available in your specific system setup.
Instructions for operating the ECL 2000’s service menus are provided on page 39.
