Turning off my heater with the pause button on the return pump controller - Apex

[Dr4gula.f32]

My return pump controller has a pause button for feeding. When I press it, the heater heats up an AIO chamber for 5 minutes then dumps that water into the DT. I'm mainly annoyed by the inconsistancies in the datalogging and want to eliminate them. So I want the heater to turn off when the return pump is less than X watts. See my current program below. But it gives me a new problem. The heater now stays off till the temp drops below 77. I want the heater to come back on, when the return pump comes back on. How do I make that correction in the below program?



Fallback OFF
If Temp < 77.0 Then ON
If Temp > 78.5 Then OFF
If Output Return_Pump Watts < 10 Then OFF

What about this?

Set ON
Fallback ON
If Temp > 78.5 Then OFF
If Output Return_Pump Watts < 10 Then OFF
Defer 1:00 Then ON

I thought Fallback ON was dangerous to use on a heater?

How about this:

Fallback OFF
If Temp < 77.0 Then ON
If Temp > 78.5 Then OFF
If Output Return_Pump OFF Then OFF

I agree with you. Fallback OFF for a heater could cause issues.

Just reread your post. update to my previous post:


Fallback OFF
Set ON
If Temp < 77.0 Then ON
If Temp > 78.5 Then OFF
If Output Return_Pump OFF Then OFF

Excluding the pump on/off issue for now, if 77 is too low then just raise the heat ON setting? I mean the heat is already cycling between 78.5 and 77, what does it matter if it drops to the low after the pump comes back on, its still with in your set range, right?

As far as the heat going off and on with the pump, it could be a simple as putting the temp probe on the same chamber as the heater?

The Apex commands are read top down (except for min time and defer), so maybe...

Fallback OFF
Set OFF
If Output Return_Pump Watts < 10 Then OFF
If Output Return_Pump Watts > 10 Then ON
If Temp < 77.0 Then ON
If Temp > 78.5 Then OFF

The heater wont turn off with this program for some reason. When I hit pause on the return pump, the heater stays powered up.

I dont want to see the temp fluctuations when I am looking at the temperature log. That's why I want to fix this.

I think it’s an order thing, with that programming the heater would turn back on if the temp were lower than 77.

Maybe this will work

Fallback OFF
Set OFF
If Temp < 77 Then ON
If Output Return_Pump Watts < 10 Then OFF
If Output Return_Pump Watts > 10 Then ON
If Temp > 78.5 Then OFF
