Hi all,

I want to setup a profile (on/off) for my fancoil so that would be shutoff when inside temperature is less then 22C or bigger then 24C (between 22 and 24 C i want to have a natural ventilation by opening the window) and also i have setup my windows to open when the inside teperature is between 22 and 24C and outside temperature is bigger then 18C and outside temperature is less then 24C, but for some reason i can not make a condition that contain inside temperature (ta).

Thank you

You can make a formula profile that uses the if and or operators. Have a play with the info from here... Most of all of the issues are already answered in the help pages. http://www.iesve.com/downloads/help/Thermal/APPro.pdf pg 24.

I read the .pdf but again the condition is working only for windows not for my flow controll. What i want is to shutdown fancoil system while the window is open, so the way i see it is to close the fan flow controler while certain temperature are met (inside/outside temperature) but for some reason when i use this formula (flow control is on when ta<=22C and ta>=24C) i recive error but it is working very good for my windows and i use this formula (windows is opening when ta>22C and ta <24C and to>18C and to<24C).
The program is not letting me to use inside temperature condion for my fan flow controller, but it is ok to use it for windows program.
