LOVE TSS2-2100 Programming help
 

I have wired a TSS2-2100.
I have cooling hooked up to output 1 and a heater connected to outut 2.
I have the following options set on the controller.

P5=1
c1=dir
c2=inv
r0=dep
SP1=70
SP2=60

Output 2 is not working as expected.
The temperature is 65 and output 2 is getting power. Output 2 should not get power until the temperature is <= SP2 (60). I pulled terminal 11 and confirmed power is on when the temperature is 65. Why?

Output 1 works as expected, if the temperature rises to the SP1 point, output 1 goes hot.


I have the controller wired as this:
1 probe 1 wire a
2
3 probe 1 wire b
4 neutral
5 power
6
7 power
8 switched hot - cooler
9
10 power
11 switched hot - heater


I searched the threads here and I think I'm wired correct. I am missing something?

Thanks,
JD

I am at work, will explain later.

For right now enter the following.

SP2=0
r 2 = 10
Now by changing only SP1 the heating output will always come on 10 degrees below the SP1 set point.
Let me know the effect.

That worked.

I'll let you explain when you get a chance.

If you prefer to use SP2 like in your above post, do the following.

r0=ind
SP2= 65 for example
r2= .5 for example

Output two will turn on at 65-.5=64.5, and turn off at 65.

Have to run

Claudius

Example #1
Operation mode ON/OFF ON1 with r0 set to ind, c2= inv.
Relay #2 turns on when temp probe 1 is less than SP2-r2
If we set SP2 to 60° F and r2 to .5°F the relay 2
turns on at 60 - .5= 59.5°F
turns off at SP2 or 60°F

If we set SP2 to 60° F and r2 to 2°F the relay 2
turns on at 60 - 2°F= 58°F
turns off at SP2 or 60°F


Example #2
Operation mode ON/OFF ON1 with r0 set to dep, c2= inv.
Relay #2 turns on when temp probe 1 is less than SP1+SP2-r2, off at SP2
If we set SP1 to 60°F, SP2 to 50°F and r2 to 1°F the relay 2
turns on because temp is less than (60+50°F-1°F=) 109°F
turns off at 50°F

See example #2 if r0 was set to dep

Example #3
Heating and cooling automatically without changing SP2 every time you change SP1 to have the same temp differential between cooling & heating.

You can set SP2 = 0, r0 set to dep,
r2= 25°F and SP1 65°F as per your above settings without worrying about SP2 and have the same result.

Relay #2 turns on when temp probe 1 is less than SP1+SP2-r2, off SP1+SP2
65°F+0°F-25°F= 40°F relay turns on
65°F+0°F= 65°F relay turns off
Every time you change SP1 the heater comes on when the temp is 25°F below SP1 (r2 setting) without changing SP2.

Since my setup has a very narrow band between cooling and heating (1.5° F)
I turn the heater off before the temp reaches the set point SP1 to prevent an overshoot, and unnecessary cooling cycle.
My SP2 is set to -1.4°F for my requirement, heater has large terminal mass compared to the heating volume of my cube fridge.

If you need more info about negative temp for SP2 send PM, boring subject.

Cladius I can't thank you enough for the explanation on the TSS2 2100 Love controller. Just finished hooking mine up to my brand spankin new fermentation cabinet and couldn't have done it without your posts on this subject. Thanks again

Could not have programmed my new Love without this thread. Big thanks!! I am a cpu guy and looking at the sheet it came with made me want to drink, but hey, waking up makes me want to drink :)

Good info, helping me mess with setting mine up. Don't have the hot side down yet but I see the logic behind it, lol. Fermentor hasn't been refurb'ed yet anyway so it is just running my keezer while I play with it.

So I'm horrible with electronics but I'm trying to program this thing right now and am having a lot of trouble. I have it hook up according to http://www.homebrewtalk.com/gallery/...SS2-210021.bmp but I don't have it hooked up to a heater as I am not using one yet. I lost all the paperwork that came with the controller but I've been trying to comprehend the manual that I found online. When I plug it in, it beeps with the error message "ErP Error of the probe not shown on the display." How do you set all the options as described above?
