NIBE heat pump + W500 cycles

Hi.
Has anyone integrated the Aqara W500 floor heating thermostat with a Nibe heat pump in a hydronic underfloor heating system, taking into account the system’s thermal inertia?
The Nibe documentation warns that changing setpoints more than once every 24 hours can reduce efficiency and cause unnecessary cycling.
Does the W500 support any form of hysteresis, ramp control, or PID tuning to limit rapid temperature adjustments?

I’m particularly interested in whether it can be configured to ‘queue’ or delay setpoint changes to respect the 24-hour guideline.

Is short cycling on the heat pump something I should worry about while using the W500?

@Boltikarie Hi there!

Your query about integrating the Aqara W500 floor heating thermostat with a Nibe heat pump in a hydronic system is quite insightful. The W500 is designed to optimize heating efficiency, but it’s essential to understand its capabilities in the context of your system.

The W500 offers features like custom temperature buffers (0.5-3℃) to reduce frequent on-off cycles, which can help stabilize the indoor environment and reduce energy consumption. This feature might indirectly address your concern about unnecessary cycling by ensuring smoother temperature transitions.

Regarding specific functionalities like hysteresis, ramp control, or PID tuning, the reference information does not explicitly mention these capabilities in the W500. However, it does support precise temperature control with sensor options and calibration, which could help in managing temperature adjustments more efficiently.

The thermostat also has an energy-saving feature that pauses heating when a window is open or when there’s a sudden temperature drop, potentially helping with your efficiency concerns.

For now, it might be wise to monitor how the system behaves with the W500 and consider these features to potentially mitigate short cycling. If precise control over setpoint changes is critical, you might want to explore additional solutions or community insights.

Feel free to share your experiences or any updates on your setup, as it could greatly benefit others in the community!

hi Boltikarie,
you can absolutely enable the hystheresis function which is available in Zigbee mode. Hopefully it will address your concerns.

Hello, yes, hysteresis is there, 0.5÷3 °C, step 0.5. I recommend additional control using automation in Aqara. You may be interested in this topic. Methods for controlling room temperature using Aqara devices

Thank you both! I’ll take a look at the article.

I took a look at the article. I think it’s a different context, but I appreciate sharing it with me.
