[TRNSYS-users] Type-2b??? (part2)

Sorry I just missed one thing:

-          You have to set your “lower input temperature” to 20.5, as it is
now your fixed temperature to compare with.

I forgot to do that in the modified project... sorry my bad.

 

However, you’ll see that the signal won’t go to 0 when it reaches 22 C (in
your schedule), as it has to strictly go over 22 for the signal to switch to
0. So if you put in your schedule 23C instead of 22C, you’ll see the signal
switching.

Dear Trnsys-colleague,

It is unbelievable but I have spend more than one hour on that and still
doesn't work...the point is:

 

I would like to switch off a signal when the difference between the High
Temp (fix to 22 ) and Low Temp is less than 0 and switch on again when the
difference is higher than 1.5..are you able to do that?

 

At the moment in my deck (attached) it seems that instead off an hysteresis
loop I have just a value limit 1.5 where is ON and OFF around it!!!

 

Thanks a lot and suggestions are well accepted

 

Francesco
