Posted by: @mjrSo, I wonder whether the settings influence AA mode as well as room temp mode
I just want to check I'm not miss-understanding something. I thought Room Temp Mode, and Auto-Adaptive Mode were the same thing, the two names just get used interchangeably?
@sunandair looks like its a Salus MP200A. adjusting the pump speed via the FTC panel. when changing between 1 & 5 I hear nor feel any change from the pump (I presume this is the pump I am adjusting!)
Posted by: @sunandairis it true that you don’t get cycling when doing the DHW re-heat and this is generally at a higher set temperature?
You will not get cycling in DHW mode because the heat pump is working harder, so is operating within its specified control envelope. Cycling occurs when the heat energy demand is lower than the minimum heat energy output, so the heat pump must periodically stop to prevent overheating the building.

You little devil, you've been reading the instructions again. Shame on you. 😋
@gotaashp in post #2 of this thread, MJR states:
Now, a possible saving grace: you have an ecodan so you might not need to figure out the curve for yourself. If the right switches are set in the unit (and they are by default), the "room temperature" mode is replaced by an "auto adapting" mode where the controller is supposed to learn for itself what temperature is needed given the current indoor and outdoor temperatures.
which also made me wonder if my system is configured from Room Temp or AA. I don't know if there is anyway of telling?

Room Temperature and Auto Adaptation are indeed the same animal. 😎
There are 3 heating modes
• Heating room temp. (Auto adaptation)
• Heating flow temp.
• Heating compensation curve.

lol. Assuming I've not missed anything, I do wish they would standardise the naming. I'm guessing they re-branded it at some point.

It's just good business. Confuse the customer with 'smoke and mirrors', so they have to pay for a visit from the expensive Service Engineer. Simples. 😎
after doing some googling on the pump (Salus MP200A), I read...
This pump is equipped with a control panel on the front for easy operation by users.
...which I guess might enable me to adjust flow speed. The problem being, the said control panel's face is hard against the floor and little/no chance of reading the display. I guess I'll have to live with the flow rate (17/18l/m (range 10-25)) but was hoping that a slower flow would help improve DT (currently at 2)
@si-fillo it’s possible you have a bespoke installation where the pumps may be off the shelf and don’t respond to the ftc controls.
We have 2 independent pumps with 5 speed settings controlled from the pump itself. Push button with neon speed indicators. The system still reads the flow rate.
Perhaps your installer can tell you how to adjust the pump speed and if you have more than one pump you will possibly need to adjust all pumps to get a reduction in flow rate. Without knowing more about your system it’s difficult to be more specific than this at this moment.

What happens if you run room temp mode with the Auto Adapt dip switch 5-2 set to inactive? I haven't tried it nor do I know if it's even possible.
