LM393A: equivalent resistance

Part Number: LM393A

Hi,

I am using LM393A for a window comparator application.

I am using 3 ntc in parallel and one of them is given as input to the window comparator. I have 3 point voltage divider for the reference voltages of the window comparator.

could you please suggest if the ntc's temp_slb1,temp_slb2, temp_amb (from figure) should be placed in parallel or series?

Thankyou

Regards
