Fighting with the fan mode (and some other confusions)

[chabad360]

I've started using VT on top of my Sensibo controllers to help manage the split units in my apartment. In the process of getting setup, I've experienced a few issues:

1. After 10am, I set the target cool temperature in my bedroom to 21°C (from 18°) to just keep it cool during the day (the crappy unit will have trouble keeping it cool at night otherwise). For some reason, the temperature regulation decides to set the target temperature on the actual unit to 22°C. I would think that it shouldn't try to raise the temperature if it's on Cool mode.
2. Additionally, if I try to change the target fan mode (from Auto) it keeps fighting with me and changing it back.
3. The unit in the living room doesn't do a good job self-regulating, so I've been relying on the auto-start/stop functionality to turn off the unit once the target temperature has been reached. But this also turns off the VT thermostat, which means that it never turns back on. My understanding is that it's supposed to shut off the underlying climate not the whole thermostat.

Hello @chabad360 ,

I would think that it shouldn't try to raise the temperature if it's on Cool mode.

Why ? self-regulation works on the both mode. I don't see any reason to avoid self-regulation on Cool mode. And you can always deactivate it if you don't need it.

if I try to change the target fan mode (from Auto) it keeps fighting with me and changing it back.
If you want to change manually your fan mode, then you must deactivate it from VTherm. It is possible directly through the VTherm UI Card. Just click on the icon with fan and A. You should have this:

Then VTherm will not touch the fan mode, and you can control it manually.

The unit in the living room doesn't do a good job self-regulating, so I've been relying on the auto-start/stop functionality to turn off the unit once the target temperature has been reached.

Ouch. This is not how it is supposed to work. You have the self-regulation with different level to do that. auto-start/stop is only for shutting off when the device is no more needed. Really not for regulation. Your device will not appreciate to be turned on and off.

Thanks for replying.

I can't use the Both mode (seems to be some sort of incompatibility with sensibo), on the Cool mode I would think I don't want it to self-regulate up, I still want to self-regulate down. But that's not really an issue. If that's the way it is, it's just annoying, not a deal-breaker.

Then VTherm will not touch the fan mode, and you can control it manually.

Hrm. I don't like the vtherm card, but I see there's a way to do it with an action, maybe I'll try to set something up. I feel like that should not be necessary tho. Just the act of changing it should tell VT not to change it from what I set. Is there a reason why it always needs to override me unless I disable the auto?

Ouch. This is not how it is supposed to work.

By self-regulation, I meant the internal regulation in the actual unit. It just keeps pumping cold air long after the room as reached temperature. Self-regulation is not helping either for some reason. So it can run for as long as needed, but at some point I need it to stop if it won't stop itself... But annoyingly, the VT doesn't act like a thermostat in this case, it just shuts itself off too...
