Hi,
You can also add insurance in the event the temp probe fails or comes out of the water. You can shut down anything that may heat or cool the tank as well as fire off a email to alert you to the alarm.
If Temp < 50.0 Then HE1 OFF
If Temp < 50.0 Then LT1 OFF
If Temp < 50.0 Then LT2 OFF
If Temp < 50.0 Then LT3 OFF
If Temp < 50.0 Then CTM OFF
If Temp < 50.0 Then FAN OFF
If Temp < 50.0 Then CHL OFF
Cheers,
