Hello to everybody!

When i try to apply set points for heating and cooling i have a problem that i can't solve.
First of all i have set points at 26 for cooling and 20 for heating. but all i get is that the temperature go between 20-26, even though the schedule i have is 00.00-08:00-->0 , 08:00-16:00-->1 , 16:00-24:00-->0.

So from 16:00 to 08:00 the temperature go till 20 when it is cold outside and till 26 when it is hot, eventhough , heating and cooling is turned off because of the schedule. any ideas??

Thank u!

Hi Vagias,

There is a good example in the TRNSYS examples of a TRNSYS model of a building with a heating and cooling device, and a controller with heating/cooling set points.

There is an article on our TRNSYS GURU website which will show you how to include a schedule to that example model to ensure the HVAC heating/cooling device only operates between 8am-4pm.

Have a look and see if that helps to solve your problem: http://help.trnsys.guru/hc/en-us/articles/216759867

Try outputting several variables to an online plotter to see where the linking of information is breaking down.

I don't mind if you send me your Studio files and I'll have a look.
Kind regards,
