Itc-308-WiFi - possible issue?

Maybe I don’t fully understand how the heating and Cooling difference works but this is what I’d like to achieve (and think it should?)

This is for an aquarium.

I’d like to set the SV - setting Temp at 25c

I’d then like to have the heating come on at 24c and the cooling at 27c

Whatever I set the CD and HD to in the app it doesn’t seem to make a difference.

As soon as the temp changes 0.1c either the cooling or the heating comes on - the only time the cooling or heating isn’t on is when the actual temp matches the setting temp.

Am I not understanding how this is meant to operate or what am I doing wrong. I don’t want the heaters or coolers on basically all the time when the temp varies 0.1c.

please help!

Thanks

Hello,
According to the description, the ITC-308-WIFI may have triggered a special mode.
Please set SV=25, HD=1, CD=1 and exit the settings. After allowing it to run automatically for 2-3 cycles, it will enter normal mode.
For the triggering conditions of the special mode, please refer to the post:
