Turn two heaters on based on temp

[chase]

Trying to use temp 1 for turning on a couple relays with heaters. Was wondering if I just added the && (Heater2, 5) to my existing code, if that would work? I just have the 5 on for a delay to keep the heaters from toggling off and on.

Code: Select all

// Turn on Heaters when the temp < 77.0 degrees
          if ( ReefAngel.Params.Temp1 < 770 ) ReefAngel.Relay.DelayedOn(Heater, 5) && (Heater2, 5);
          // Turn off Heaters when the temp > 77.1 degrees
          if ( ReefAngel.Params.Temp1 >= 771 ) ReefAngel.Relay.Off(Heater) && (Heater2, 5);

Thanks for the help!

What is Heater2?

Adding the && (Heater2, 5) would not work. That would not be a valid statement. You have to make it an entirely new statement.

Code: Select all

if ( ReefAngel.Params.Temp1 < 770 ) 
{
  ReefAngel.Relay.DelayedOn(Heater, 5);
  ReefAngel.Relay.DelayedOn(Heater2, 5);
}

You do realize that DelayedOn delays the turning on of the port by the specified number of minutes only after the controller starts, exits feeding or water change modes. It does not wait the specified number of minutes after each toggle.

Also, I'm assuming that you have Heater2 defined as a port number for the relay box.

I use a back-up heater when it gets too cold. Here is the advice I got for that...

Oh, okay I thought that's how it worked. Is there an option to put a delay timer on a port to keep it from rapidly toggling?

if you are talking about that for relays based on the temperature, i would make sure direct temp sensor is not enabled. i do a smoothing out of the temp and prevent rapid temp swings. its not perfect but can help. it requires a controller reboot though if you unplug a sensor though based on the logic. so you may want to look at that.

Or just increase the histerisys.
you are using 77.0 and 77.1, increase it to like .5 degrees.
