I wired my Johnson A19 to a split outlet so that I can plug in a lamp for heating mode or my freezer for chilling mode. I wouldn't recommend using both at the same time because it would unnecessarily force faster cycling of both. But this saves me from opening the A19 and rewiring it when the weather changes.
To split the outlet, you need to break the tab on the hot side of the outlet. I'll put up a schematic if anyone cares.
NOTE: there are many similar-looking models of this thermostat. I think a lot of the pre-wired ones from the brew shops are SPST (single-pole single-throw) relays; in that case, they WON'T work. You must have a STDT. check the following table to see if your's is on the list. I think the brew shops carry the A19-AAT, which is a SPST (won't work). That one for some reason isn't in this table.
I think I have a -ABC model, but not sure.
Here's the wiring diagram. Really simple. Just make sure to break the brass tab or both outlets will be on all the time.
