Hi,
I'm trying to do simple incubator using thermostat found Here , but faild to find the correct values of Rs that make the window of ( 35C to 39C ) required for good hatching chance.
my NTC (R1) is about 9k in room temp and around 7k under the body temp ( around 37 C), R2,3,4,6,7=10k and R5 is a pot 10k. I've added a capacitor of 220uF parallel to the relay k1.
With the above values, I've turned R5 both sides fully, yet no response to the temperature change.
What do you think that I need to correct ?
EDIT: the working link is: **broken link removed**
