What do you need to know, here is mine.... WS-1500EPM is my model, but from looking at the manual they function the same.
Output is 120v AC via an internal SSR. So you need to basically wire a plug to the element in the MES and plug it into the outlet on the back of the Auber. To set for single mode (1 temp for entire cook), simplest way is:
Push "Set" until display says "C-1", use +/- to set desired target temp for pit
Push "Set" again until display says "T-1", use +/- to set desired time at this temp. For a single temp cook, just set this to way more than you need. So for a 4 hour (240 minute) cook, set it to say 600 minutes, etc...
You have 6 presets of temp for a period of time. You can set them all the same temp, and long times and it is a one temp cooker if you do that. Or like was stated earlier for sausage if you want it to run at 120* for 60 minutes to dry the casings, then step up to 130* for 90 minutes, then to 140* for 90 minutes, then to 150 degrees for 60 minutes then to 165* to finish, you can do that. Once programmed like that it will run the entire smoke and do the temp changes on cue for you.
