Hot-water circuit (cont.) ECL 2000 Type 2:
The motor valve M3 controls the storage tank temperature, which is measured by
the sensor S6. During tank heating, the motor valve M3 performs PI regulation of
the return temperature in the hot-water circuit measured by S11. Because of the
delay caused by the storage tank and the return temperature control, the integral
action must be disabled. The circulation pump P3 is controlled according to the 7-
day program.
You use the controller’s service menu to set the parame-
ter Integr. time to 0. This disables the integral action.
Appendix C of this Guide provides an overview of the
service menus. The ECL 2000 User’s Guide (ref. [2])
provides instructions for operating the service menus.
