New to 3D Needs help

Bought myself a Sintron Prusa i3 and after a 'few' issues putting it together and then getting the electronics working (complete new Stepper Motor drivers) I finally tried to print and get the attached errors. Anyone give me some guidance?

Thanks

max temp settings do you have a heat bed if not you will have to tell the firmware that you have not

Very new and very uneducated in 3d printers with a prusa i3 hephestos. This was given to me in a slightly ‘used’ condition with the lcd screen showing two parallel bars.
I’ve managed to use the ‘blink’ facility on arduino IDE and I’ve located the hephestos firmware on Marlin as I assume it’s that part that’s in need of reloading.
I’ve assumed that as I’ve been told a previous attempt at renewing the firmware failed. Hence the LCD display as described.
So my problem is trying to load the config h and config avh into Arduino IDE, I keep looking for a marlin.ino or pie file iwithin the zip file. I’m at a loss to understand how to progress loading the contents of the appropriate marlin zip file into arduino IDE, im sure it’s simple but I’m struggling to understand how.

Can anyone point me in the right direction please?

Thank you

My previous msg I failed to note that the marlin.ino/ode file is not in the marlin.zip file.
