[Equest-users] hot deck temp

[Verena Kindl]

Sorry to bother you again, but i am still trying to fix my problem (to
achieve a room temperature of 72-75 F with an IU unit). I think my
mistake is that I  put the zone entering and hot deck max leaving
temperatures both to 68 F and therefore I can not get 72 F room
temperature even so I specify the design temperatures to 72/75 F.

 

 

 

Which one is the main air handling unit coil and which belongs to the
fan coil unit? I tried :

Main AHU coil ?

  
   

FC max leaving temp?

  
   

 

But then I get a warning:

 

 

Shall I ignore the warning as the room temperatures are fine or do I
have to edit something else?

Betreff: zone temperature

 

Hello all,

 

I specified for my IU system the design temperatures at 75/72 F and the
thermostat setting points to the same range 75/72 F ( cooling/ heating
). I supply the air with 68 F and the FC in the zone should do the rest.
For the first glance I let equest autosize the circulation loops. So I
expected that the space temperatures are always between  72-75 F ( as
the fans are running 24 h ). But this is not the case, it is mostly
according to the SS-O report between 65-70 F. I created also an hourly
report to monitor the zone temperature but there I can see the same
result ( obviously it should be the same as space=zone ). The cold and
hot air flows are also zero does it affect my result ? I was thinking it
is maybe the temperature I supply the zone with (68 F) and not the
actual zone temperature but then it should be always 68 F. Any idea ?

 

Hope u had a good week start.

Regards

Verena
