Heater control error

[dmsc2fs]

I am trying to setup my reef-pi to control my heater and I am stuck. If I understand correctly Heater Threshold is the target temp? What would I set Hysteresis at? have tried from .05 to 100 and it is always less than the acceptable value. Isn't Hysteresis the high and low set points? If I have a 1 in this field I would expect the temp to swing above/below 75 by 1 degree?

Don't have any experience yet, but have you tried:
- giving the threshold a dot as well, say 75.0 or 75.1
- typing the threshold with the european style: 75,0 and 0,2 ?

Somebody else had a similar problem recently, maybe it is somewhat connected.

Thank you for the ideas. The threshold isn't the issue. It is the Hysteresis that is stating the value is less than acceptable. A comma doesn't work or any combination of values that I have tried.

I think you might have to enable the chiller option, as you don't want to control anything setup a dummy piece of equipment you can connect to it.

Well, you never know how it is handled in the background ^^
I had a look at the code and even though I don't quite understand the structure, there are checks and interdependecies against the heater, cooler and certain maximum and minimum temperatures. So @robsworld78 might be right about that Cooler thing. You could try further:
- Retype all settings to make sure they are set to the right value internally (so, delete/change the value, confirm, and set to the old value again)
- Restart Reef-Pi and see if all values are still there.

Another thing that might be usefull: which Reef-Pi version are you using ? That could help @Ranjib to figure it out ^^

You are correct. I found the bug on github that explained how to resolve.

Assign equipment or macro to the chiller and give the chiller a threshold. After this you can assign a Hysteresis and save the config. Next disable the chiller and you should be good.

Sorry folks , this is an annoying UI validation bug that I have to fix . It’s not something related to backend logic . The web ui validation has a bug that does not allow saving controller settings without a chiller . :-( , I just have to get the time to fix it

Hi Ranjib is there a work around for this while we wait for the bug fix?

Yes, you can create a dummy equipment and assign that.
