Hello everyone! I wanted to share my experience with my HmIP wall thermostat and some tips I’ve learned along the way. I’ve been using it to control two radiator thermostats in my living room, all integrated into a single group in my CCU3 system. It’s been working great, but I recently noticed something a bit puzzling.
The temperature in my living room group kept automatically increasing and wouldn’t go back down. This was a bit frustrating because I had the group set to manual mode, and no programs or scripts were running. The only thing I could think of was the automatic baseline calibration (ABC) feature, which I had enabled. The ABC algorithm is supposed to adjust for long-term drift by tracking the sensor’s lowest reading over a set period. But in this case, it seemed like it was causing unintended temperature increases.
After some research, I discovered that the ABC feature can sometimes be too aggressive, especially in environments with fluctuating temperatures or drafts. To address this, I decided to disable the ABC calibration and switch to manual calibration instead. This involved resetting the baseline manually using the calibration button on the thermostat. It’s a simple process, but it made a big difference in maintaining consistent temperatures.
I also found that keeping the thermostats away from direct sunlight and ensuring proper airflow around them helped stabilize readings. If you’re experiencing similar issues, I’d recommend checking your calibration settings and considering a manual reset. It’s also a good idea to review your group settings and ensure no unintended programs are running in the background.
Overall, my experience taught me the importance of understanding and fine-tuning the calibration settings on smart thermostats. They’re powerful tools, but sometimes a bit of tweaking is needed to get them working just right. I hope these tips help someone else avoid the same frustration!
Happy heating!
