[TRNSYS-users] Multiple zones on same mechanical components

[David BRADLEY]

Just as in real life a thermostat cannot get information from more than 
one sensor so too the TRNSYS thermostat model can only monitor one 
temperature (although it shouldn't crash if you try to connect more than 
one; we'll look into that). You need to decide in which Type56 zone your 
thermostat is going to be located. The temperature control in the other 
parts of the building isn't going to be as good but again, that is how a 
building works in reality. You can of course feed the Type56 zone 
temperatures through an equation or a component that takes the average 
temperature of the Type56 zones and then allow your thermostat to 
monitor the average temperature rather than a specific temperature.

kind regards,

  David
