You can use type 95 (utility library) to obtain a "signal" when a day corresponds to weekend or holiday.

Yo have to define by yourself the number of holidays to be considered and their corresponding dates.

The Output 9 "Holiday flag" is the signal you need {0,1}

You can use the Forcing Functions in Utility Libarary to set the time schedule.

Thank you sir

Where we should link it? on the controller?

I was trying with the forcing function, type 14k.

You can link it to pumps, chiller or boiler.

Yes, I have tried Sir.

I have a pump controlled by differential controller and, to link the forcing function with the pump, I must undo the linking between the controller and the pump which cause me a wrong working of the system because the differencial controller is no more controlling it (the pump).

What REALLY want is to stop the domestic consumption of water, eg for two weeks.

Thanks you any ways, I appreciated.

Kind Regards

If you have different operation for different days, what you can do is to define:

- One "daily" forcing function (type 14h - general) for each type of day (i.e. weekdays, weekends, etc.)

- One seasonal signal ( type 95) -> calendar events (day of week, week of year, etc.)

- One differential controller for determining if the measured conditions require to turn the pump on/off

Then you put everything in a "'calculator" by defining operating conditions for example:

If day = weekend and even if controller signal =1 -> pump OFF

if day = week,  date between date1 and date 2 and controller signal =1 -> pump ON

Once you define all the conditions by logical operations, you can get only one signal to be sent to the pump.

I hope this helps,

Regards
