Re: [TRNSYS-users] TRNSYS time equation

Dear Marion Hiller , 
 i checked Type 14 output will not work in this situation. 
Actually i want to control natural ventilation window open and close according to the set point, at the corresponding time span. As i write before  temperature is room temperature, on behalf of that window should be open and close. if room temperature is high than the set value at particular time span window should open (natural ventilation). 

00 to 5h.... temp set point 18 C
5-10h....  temperature set point 22  C
10-18h....23  C
18 -24h...24  C

Thanks

Hello Adnan,

 

I recommend to use Type 14 instead of an equation .

Betreff: [TRNSYS-users] TRNSYS time equation

 


Hello everyone,

 

i want to use an equation for two control parameters time and temperature . like my control is  

 

00 to 5h.... temp set point 18 C

5-10h....  temperature set point 22  C

10-18h....23  C

18 -24h...24  C

 i need to get output as 0 or 1,  i am already using the following equation which is only allowing me to set one temperature set point, i need to set different temperature set points during complete one day.

 

GT(Temp,20)

 

how i can add time function with this equation

 

Thanks
