Re: [TRNSYS-users] control function for shading system

[Adrien JEZEQUEL - ITF <a.jezequel@itf.biz>]

Dear Rana,

If you use Type 2D,

1. connect radiation you need to Input 1 : Upper Input Value
   
2. connect Output Control Function to Input 4 Input Control Function
3. Put 0 in Parameters 1 to 4
4. Put 972 in Parameter 5 : Upper Dead Band => your control will be on when irradiation > 270 W/m²
   
5. Put 972 in Parameter 6 : Lower Dead Band => your control will be off when irradiation <  270W/m² (you may change this value to obtain an hysteresis effect)
   

If you use TRNSYS 16, you may also have a look to examples (building.tpf) and TRNSYS documentation. You may alos use wizard to see how are used Type2 in studio.

Best regards

Hi all,

i am having a building with internal and external shading system. the external shading system is on when it the irradiation on window reaches 270w/m2 or more, and  if it is less it went off. and i want to put this in the simulation by using a control function and connect it to my input,,, so which control function could be used is it type 2d or the PID controler type 23..

and if it is in the 2d, how to put this number.
