@tiger_cook `Antifrost` is definitely disabled on my setup, and I found it by trying to understand exactly what you’re going through now.

If you disable that setting, at 6C or below you will still see `Sampling` however at `60% pump speed` periodically per your previous posts even if Space Heating is set to `Off` - that should be considered normal and the best you can do in `LWT` mode.

Unsure if you have the same issue that a few of us have resolved on the bigger units where tape heaters were always on when the pump ran (even above 6C!) - I shaved ~80watts (50%) off the power usage during sampling by fixing this issue that is for some reason the jumper cable is in place (incorrectly) for U.K. Daikin units.

> I had a visit from a Daikin engineer today. He installed new firmware on the outside unit that is supposed to help the response time of the expansion valve. I also reported my concerns about the inlet water tape heater that I mentioned here: The engineer has fixed the wiring for that. It sounds like some jumper or connection was set incorrectly. I disconnected ESPAltherma before the engineer visit, so as not to freak him out. smile I’ll reinstall it over the weekend and see if I get clos…
