Valves with a motorised actuator need a certain time (known as the valve run-time) to open or close completely. This SERVice parameter is used to set the equitherm EQJW 125 to the run-time for the valve drive that is being used. Optimal control quality and various protective functions are only ensured if the valve run-time is set correctly.

Summer/winter or winter/summer time-change SP23, P24 Thanks to the calendar time-switch integrated into the equitherm EQJW 125, the winter/summer time-change and the summer/winter time-change are carried out automatically. The date for the change-over is specified by the value for SERVice parameters SP23 and SP24.
