Thanks Jeff,
The detail is like that...

Case 1
                                                                              EQUATION Editor                                                
Weather data --------------------------------- Solar radiation                                       Win_id_1 =   0       
                                                                                                                             Win_id_2  = 1  
                                                                                                                             Win id =    GT(Solar_R,100)*Win_ID_1+(LT(Solar_R,100))*Win_ID_2 ----------------------------------------------------------Type 56 input (for controlling Window) 

Case 2

                                                                                    EQUATION Editor                                                                                          
                                                                                                                             Win_id_1          
Weather data----------------------------------- Temp                                                    Win_id_2
                                                                                                                             Win id =   GT(Temp,20)*Win_ID_1+(LT(Temp,20))*Win_ID_2  

BOTH CASE 1 AND 2 WORKS FINE.

Case 3 
now case three i want to control both temp and solar radiation combine and need to get one output for TYPE 56

Like when temp > 20 and solar radiation > 100 output should be 0.. and when temp < 20 and solar radiation < 100 out put should be 1

Hope this explanation will help. 
Thank you very much for looking into my problem.

Regards
Adnan

Adnan,

You didn’t give us enough information to be able to write the equations.  What happens when the radiation is high but the temperature is low?  And the opposite condition?   But we can set it up in a basic format for you to edit:

Equations 3
SolarHigh = GT(Solar_R,100)
TempHigh = GT(Temp,100)
Win_ID = SolarHigh*TempHigh*ID1+SolarHigh*(1-TempHigh)* ID2+(1-SolarHigh)*TempHigh*ID3+(1-SolarHigh)*(1-TempHigh)* ID4

Basically set up your equation to account for all 4 outcomes.  Just fill in the correct ID in the equation above and you should be good.

Hello everyone,

i am using simulation studio's equation editor, two equations with different parameters set values separately, and they work fine now i want to control two parameters together with two equation combine how i can do this

my equations are e.g

1) win_id_input = INT(GT(Solar_R,100)*Win_ID_1+(LT(Solar_R,100))*Win_ID_2 

 2)  win_id_input = INT(GT(temp,100)*Win_ID_1+(LT(temp,100))*Win_ID_2  

need one out put both conditions together, 
Thanks in advance
