Default help with Love TS programming

I'm looking for some coherent write ups on what/how to use the different settings mean for the Love TS single stage contoller
( http://www.coleparmer.com/catalog/pr...sp?sku=9352000 )
I've come across some posts before, but didn't bookmark them.
Can anyone else run me through the steps to set the parameters from scratch? just got it in the mail and I'm trying to brew this weekend. I don't want to spend a week troubleshooting the settings while my wert gets ruined. thanks!

Did it come with an instruction book?

It should be as simple as setting a temperature, setting it to cooling or heating, and setting an overshoot value. You may also have to choose the input device (thermocouple, thermistor).

While I am not familure with that controller, I have programmed LOVE PID controllers before. Using it as an on-off is pretty easy to set up. Maybe take ya an hour. Good Luck!

Coincidentally I programmed mine for the first time last night. I can't give full instructions but here's what I found:

When you first give it power it's showing you the current temp. Mine was 69F.

  • Hit the Set button
  • You will see the code "SP" (I think)
  • Hit the Set button again (Mine showed a 3, confusing, but that is 3F)
  • Change the designed number using the up/down arrows. (I set mine to 63F)
  • Hit the Set button again (goes back to "SP" - this may not be necessary)
  • It's done, it will reset in a minute out of programming mode or you can click Set and Down at the same time.

Mine seems to be working fine other than possible reversed polarity. The instructions can make it seem very complicated when in reality the initial setup is quite simple, almost too simple.

EDIT:
Link to PDF instructions.

Thanks. I just got word it was delivered, so i haven't opened the box yet. I've been trying to learn about this unit for the past couple weeks, because it seems like it can be tricky.
I'll give it a whirl tonight and update what happens.

I've heard people (and the manufacturer) say that it has "a good ammount of programmable functions..." Do you play with any extras, or just stick to the Setpoint, and differential settings?

Like everything it seemed overwhelming at first so I kept strictly to programming the Set Point. I only followed the steps I outlined above and that's it.

While my fermentation chamber is "ready to go" I need to drill a hole for the temp probe and pick up a computer fan to help circulate the air, can't wait to use it after I (hopefully) brew a Kolsh this weekend.

I believe the 3F is the differential (overshoot set-point). If your set-point is 65 and you have the differential set at 3F, the chiller won't turn on until it reads a temperature greater than 68. So depending on how accurate you want to be, and how much you want to cycle your heater/cooler you can increase that number or decrease it.

Does it matter if Red goes to 1 or 2 For the Probe?

Not that I can tell. Looking at several wiring diagrams none mention the color swap.

Depends if it's a thermocouple or thermistor. If its a thermistor I doesnt matter. They work by outputing a resistance. If it's a thermocouple it does matter. They work by outputting a voltage. Sounds like it's a thermocouple, is it a K, J, or another kind? Normally if you stick it in backwards you'll either get gobbily goop, or a negative reading, i.e. -65F.

From Cole-Parmer:

-1.5" (4 cm) thermistor (100Ω at 25°C) with 5 ft (1.5 m) cable (included)
-The thermistor is a PTC type.

So am i good? or do i need to double check my red/blue wiring to 1 and 2 on the control?
