Since it seems you want to live dangerously (no heater controller) there is are a few things you can use to help out.
Because you're relying on the Apex temperature probe, start with a fresh one.
If you have another module that has a temperature port on it (like a PM2 or a ASM) then use that probe as a back-up by integrating it into the control code. Using your own code from above but renaming the temp probes 1 and 2:
Fallback OFF
If Temp1 < 77.4 Then ON
If Temp1 > 78.2 Then OFF
If Temp2 > 80.0 Then OFF
Temp1 will do the regular ON/OFF of the outlet but if temp 1 fails and the temperature rises above 80.0 then Temp2 will shut of the heater before anything bad happens.
Bear in mind this does NOTHING for a stuck ON outlet control relay. And that's what I mean when I say you're living dangerously.
