Have anyne tried to set 10% of Demand Control?

[slekhano]

ONECTA has minimal value as 40%, I think Faikin allows to set 10%, have anyone tried to set 10%? Does it work? Does it decrease electrical power consumption and delivered heat power?

[dahadd]

I can only choose between 30 and 100%.
30% works

[slekhano]

What is your unit nominal electrical power?
Could you measure the reduction of electrical power usage when you switch from 40% to 30%?

[dahadd]

So I notice a change in performance when I change from 40 to 30%

Is it possible via MQTT to enable / disable demand control? Or if it happens to be disabled, does it activate just by sending "command/Faikin/demand 50" or similar? What about auto mode, is that only possible using Onecta? Faikin (MQTT) / Onecta interoperation is a bit confusing...

You just set 100 to logically be "disabled", surely?

Haven't had my Daikin long enough for proper testing, but what I've understood from other (heatpump focused) forums, 100 % (active) demand control is not the same as it being completely disabled

OK, S21 allows a number to be sent. I don't think there is an on/off.

But if you find an S21 message that does it, let me know, and I'll add.

Related to this kind of troubleshooting / debugging, I guess debug messages alone won't be enough and I would need a pass through device like shown in the manual?
