ledsen för min engelska, jag använder Google Translator för läsning

Is there anybody, who have expeerience with "Vacation mode" on IVT? I have indoor sensor and when I enable Vacation, radiator pump will start also when there is +20C outdoor. I expect, that vacation mean, that heatpump using indoor sensor and stop P2 for all "vacation" time

Finns det någon som har expeerience med "Semester läge" på IVT? Jag har inomhus sensor och när jag gör Fritidshus, radiator pumpen kommer att starta även när det är 20 C utomhus. Jag förväntar mig att semester betyder att varmepump använder inomhus sensor och stoppa P2 för alla "semester" temne

My heatpump works the same way,radiatorpump runs all the time in vac.mode,a possibility is set the radiatorpump to run when compressor runs only.

Are you sure, that it is possible to control radiator pump??? I have options only for ground pump and internal pump.

A-ha, In that case P1 will stay working.

In my documentation: P1 - Radiator pump, P2 - Heat carrier pump, P3 - Ground pump)
P2 and P3 can be controlled to work with compressor, P1 not.

As user you have access to extra functions. Keep the Heat button
pressed down for five seconds and go into Menu to gain access to
these displays. You will automatically return to level 1 again after
30 seconds.

If a room sensor is installed you can set the number of days
that the room temperature is lowered to 15°C here. The
temperature is not adjustable and it does not affect the hot
water. Normal operation is resumed when the period is
over.

If you mean the compressor will start even when it's over 20 degrees outside?
The Compressor will always make domestic hot water, even when you have vacation mode activated.

I'll hope you are satisfied with this answer?

Yes, that is I speeking about.

My expectation is, that heatpump will use room sensor for measuring this 15°C and will stop P1.

I have used this during spring -> there was more than 20°C outside temperature during day.
In normal operation my heatpump switch off P1 when outside temperature are higher than 17°C (can be adjusted in menu)
Problem is, that during "vacation" P1 never stops   Sc:,h

The questions are:
Is this correct?
Is there anybody with same expeerience?
How many people using vacation mode and have logs from heatpump about running devices during vacation? (statlink or any other monitoring)

OK, this is not so logical - it have indoor sensor and can for example start radiator pump only when indoor temp is less than 17°C or something like that. It will be more "eco".

I agree, it feels like a software bug that the pump runs continuously i vacation mode. I was surprised to see it when I tested the function during summer.

Have you expeerience with IVT helpdesk in Sweden? I have tryed to write them few emails and have no reaction to that.
Here is more "non eco" situations in software and I will be happy if anybody will read my notes and think about them.
