Help with Apex

Hi guys, I need to setup my heater to go on and off based on temperature. Does this command makes sense?

Fallback OFF
if temp <77.0 then ON
if them >80.5 then OFF

My heater has its own thermostats so I'm not sure if I have to do anything else. Thanks.

Aside from the typo, the statement looks fine. You can set the thermostat on the heater slightly higher than the Apex's. Some people including a 3rd IF statement in case of failure of temp probe, accidently draining the sump (assuming probe is in the sump) below the probe or pulling the probe out of the water -- If temp < 50 then off but that's your call to include it.

Thanks a lot, so I can just add another "if temp <50.0 then OFF" at the end?

Correct. So it'll look like:

Fallback OFF
if temp <77.0 then ON
if temp >80.5 then OFF
if temp <50 then OFF

Fallback OFF vs ON for heaters is a personal decision/debate. If it's Fallback OFF, you won't have to worry about a runaway heater or stuck thermostat should your Apex loses communication with the EB8. If it's Fallback ON, you won't have a cold tank if communications between the Apex and EB8 is lost, but now you're solely relying on the thermostat on your heater to keep the tank from getting too hot.

Ok thanks, what do you recommend? Fallback OFF or ON?

My Apex is sitting on my dining room table with an iPhone charger on it :lol2:
I've been lazy setting it up, guess I'll set it up today. Thanks for ruining my lazy Sunday! :lol2:

Personally, I would go with Fallback Off and setup email alert to notify me if my tank temp is dropping.
