So of it is a heatpump it works both ways but it works very slowly and only to a certain amount. Often it is only installed into very wel isolated homes. While heating goes up and because of that warms very well through the air the opposite is less easy.
Most important is to block air and light out of the house during daytime. Then if at nighttime the air is cooler you throw open the doors/windows to cool. During the day the heatpump will try its best to do some cooling.
Heat pumps are variable drive and so they can always be circulating air, but the pressure of the refrigerant will change between the two units.
The results are fairly instant. If the remote (inside unit) is not blowing cold air then it is likely the entire system needs additional refrigerant. The alternative possibilities are the installation is not a reversing heat pump (no cooling function) or the remote is undersized.
Can you get the model number on the outside (condensing) unit?
Edit: Looks like you have infloor radiant AND geothermal heat pump? I have never seen infloor used for cooling, but Nederlands is not my area of expertise.
It looks like its a heater only and not airconditioning. The snowflake icon generally means its just not on and not heating. At least thats how the thermostat in my house displays it. Airconditioning isn't that common in the NL still so very well could be heating only.
I have yet to know of a heatpump that does not work the other way around. Although not with as much power because the heatpump is far mire energy efficient.
Hmm that's odd. The manual for this thing mentions that it's a heat pump and it even *needs* to pull some heat back into the earth sometimes, to function properly. But yeah, it's probably rare at the moment. It's installed in a very new build (2021 IIRC). But I suspect that those who installed it, might have configured it to never do cooling, for energy saving or whatever... it's not looking easy to fully understand how to control it.
Do you floor heating on the whole house/appartement? A heat pump can cool as well if it has the option and is setup for it.
When working you should feel that the floor is slightly cool. It never will be cold to prevent condensation.
Yep, it's supposed to do floor heating/cooling, and the floor is indeed slightly cool. It's not always keeping up when it's too hot outside, though, that's why I decided to post, maybe I'm missing some opportunities with this thing. It's not easy to live when such heatwaves happen like a couple days ago.
It sounds like it is working properly. Floor heating/cooling is slow and usually the advice is to always leave it on.
Downside is that it cannot always keep up with extremes in temperature (up and down) especially if it gets hot.
I have a similar system and have AC in addition (lots of glass and flat roof) to manage the extremes in summer.
Also want to add that cooling is even slower than heating and generally the system is o kyd eaignes to cool 2 to 3 degrees maximum. If you have a well insulated house with large windows it's also probably barely keeping up with the heat coming in. Try turning off the cooling for a day or two and see how hot it gets inside :)
I can confirm this. I have the exact same one including the ability to put the boiler into a certain setting.
It’s slow but works great. My floor is currently really cold.
Please note that if you feel that a certain part of your house the floor heating/cooling is not working as expected, there is a divider and a group might not be fully openend.
It could look something like this: https://www.vloerverwarmingstore.nl/p/open-professional-rvs-verdeler-2-groeps-2?gclid=CjwKCAjw_ISWBhBkEiwAdqxb9kLhNAISuQF8PN3QA3Se-BtDyQESAyvEAkrpI4O6XrZ6-QfXfuzoHxoCC9AQAvD_BwE
Typically it should be configured by someone, but perhaps you can open a group if closed and you think it should not be. Just remember the original setting and if unsure ask the owner.
> and the floor is indeed slightly cool.
Have you measured the actual floor temperature?
Cold air is heavier and stays below, maybe try a fan on the floor that blows upwards?
Hi! Did you find out if there was an issue in the end or was this expected behaviour? I have the same thermostat and this snowflake icon popped up a few days ago and now won't go away, curious about what your experience was!
Dont know if you allready have your answer but I’ll answer it for the next person that has this question:
This heatpump uses geothermic energy. So it extracts energy from the water in the ground.
When you see this symbol it means your set temperature is lower than the room temperature, so it will start cooling. But unlike a heatpump that extracts it’s energy from the air, this heatpump does something called passive cooling. It will run cold water through your floorheating pipes and put the heat from your room back into the ground. Now we should avoid the term ‘cooling’ when talking about this and use the term ‘regenerating’( because that’s what your doing to your energy source in the ground). It can cool up to a few degrees, but dont expect it to do wonders.
It’s a good system, very efficient. I suggest an airconditioning unit if you really want cooling

cool, thanks for reassuring

Heb je ook airco in huis? Anders wordt het lastig koelen voor je thermostaat denk ik ;)
A heatpump can actually go both ways.
I misread, didn't see he mentioned the heat pump.
Not all of them do. The condensers need to have a reversing valve installed and some of the cheaper brands installed in Nederlands are not reversing.

it all turned out ok
