[TRNSYS-users] Help in type 9 (data reader)

[Shahen Fakhraldin]

 Dear TRNSYS users,

I have a txt file that represents cooling load of a building from 0 to 8760 hr (in hr timestep) and it consists of two columns (time,hr & load,kW)
And I'd like to use type 9e to read it in a project that will run only in the summer in 1 min time step.

Therefore, to understand the reading and the interpolating process of type 9e:

I connected type 9e to printer 25c (output 2 of type 9e to printer 25c) and I let the simulation run from 3624 to 3648 (for example) in a 1 hour timestep. 
The parameter of type 9e are:
Mode                                           5
Headers to skip                             1
No. of values to read                     2 
Time interval of data                      1 hr
Interpolate or not-1                       1 (interpolate)
Multiplication of factor-1                1
Addition factor-1                           0
Average or instantaneous value-1   1 (instantaneous)
Interpolate or not-2                       1 (interpolate)
Multiplication of factor-2                1
Addition factor-2                           0
Average or instantaneous value-2   1 (instantaneous)

However, when I compared the resulted text file with the original (input) load file I found a small difference between them (just the start point was the same value)
        hr     original    type9e
3624 4.08075 4.08075 
3625 3.29606 3.68841

3645 6.42763 6.88970 
3646 5.68270 6.05516 
3647 4.99971 5.34120 
3648 4.34179 4.67075 


I changed the mode to 4 but I did not get the same input values as well.
Am I selected the wrong type of 9 or there is something incorrect in the parameters

Please can anyone help me 

Kind regards,
Shahen
