NEED A LITTLE ASSISTANCE. ALL i need is to control temp at this point. I want relay contants to close at 78f and open at 83f. tried and tried to program and no luck. Can you walk me through it? Cause if you can't i'm gonna shoot it. The only wires I've hooked is power to the unit and the thermocouple red-9 and blue-10

The manual actually tells you everything you need to know, but --- what kind of relay are you going to use? Have you set the sensor type to the kind of thermocouple you're using? That's really important, because the default type is a Pt100 RTD sensor, which is not a thermocouple, and if you haven't done that, then everything will be wacko...

thanx for the reply i appreciate. Finally got it but thermo (j) isnt reading quite right. About 5 degrees to high.

You can correct it by setting "PSB", sensor error correction.

Press SET to the programming mode, enter "0089"
Use "^" to scoll to the PSB and enter "-5" and hit SET
Use "^" to scoll to "END" and hit SET

That should give you a precise reading

tanx Marco for your answer. How do you enter a negetive number? I tried every way to do it but no dice. Couldn't find how to do it in tthe manual. Thanx again

Page 2 of the manual, configure PSB using password "0089"
Use "arrow dn" to change the Left Most digit and it will show "-"

Thank you so much for the assistance. All is well.

Glad to hear that it work out
