OK here is the updated schematic for a LOVE TSS2-2100 controller with a single probe
When you first plug the controller in and fire it up a buzzer will sound and ErP will flash on the screen. Here is how to enter your controller into single probe mode:
1. Press and hold the "SET" button for 8 seconds or until "0" flashes on the screen.
2. "0" is the code to grant access to the controllers programming and can be changed to any digit 0-999 to selectively allow access tot he controller.
3. Press "SET" again to tell the controller "0" is the correct code ("0" is the default).
4. Now a parameter will be flashing on the screen. Cycle through the parameters using the "up arrow" until you reach "P5".
5. Press "SET" to enter "P5" programming.
6. Press the down arrow sot hat "1" is displayed on the screen. This indicates single probe operation.
7. Press "SET" again to select single probe operation and return to the parameter screen.
8. Press "SET" and the "down arrow" simultaneously to exit the parameter screen.
You are now operating normally in single probe operation.
To program the controller to work properly with heating and cooling as we have discussed above... follow the same programming steps (now that the beeping has stopped
) to enter parameters "r0", "c1", and "c2" as indicated on the schematic.
"SP1" and "SP2" are set by pressing the set button. The current SP1 temp will flash. Use up/down arrows to pick desired temp, and hit set again. Do the same for SP2.
Thanks again ClaudiusB for the tip!
