    Heater email alarm

    Hi,
    I have this for my email heater alarm:
    Set OFF
    If Tmp > 78.8 Then ON
    If Tmp < 77.0 Then ON
    But how do I add for in case the outlet is off? What is the code?- thanks, Tim

    Your code is stating that if temp is greater than 87.8 heater on, and if temp is less tan 77 then on, the only time the heater will be off is in between those 2 temps

    If you're wanting your tank to be in between those 2 temps your code should read:
    Set OFF
    If Temp < 77.0 Then ON

    If Temp > 78.8 Then OFF

    I'm talking about the email alarm for the heater. Not the heater range itself.

    We need clarification about what exactly you want to check for "if the outlet is off". Are you trying to detect when the internal thermostat on the heater shuts it off? Is the heater primary control with the apex as a backup and you want an email when the apex shuts it off? Please post your heater code as well.

    That isn't clear enough to provide a solution. Stops working in what way specifically. What is your heater code? Is apex primary or backup control for the heater?

    Heat code is just on @ 77.5 and off @ 78.6..It's plugged into the Apex jr. So if that particular outlet failed, and the heater had no power, I'd like to know.

    Nope, this is not correct programming. A Set statement should not be used. This sticky post explains why: https://forum.neptunesystems.com/sho...l=1#post114462

    There's no way to do that with an Apex Jr beyond having a low temp alarm configured.

    There is no way to check that directly on a Jr since it does not have amps/watts probes. If the outlet were to fail and the heater stopped receiving power, the temp would drop until your low alarm value and then you would be notified based on temp.
    If the value reads really low (in the 20s) it means the probe is disconnected or open circuited.

    If it reads in the low 70s, that means the probe fell out of the tank.

    If it reads below but near 77, it means either the heater internal thermostat or outlet is stuck OFF

    If it reads above 99.9, that means the probe shorted

    If it reads just above 78.8, then the outlet might be stuck in the ON position.
