ᐅ Active cooling without individual room control

Hello everyone,

We will most likely be able to build our new single-family house without individual room controls. Fortunately, we were able to discuss this with our construction company.

Specifically, a CHA Monoblock air-to-water heat pump will be used. Since I have limited trust in our heating technician, I would like to ask two or three questions here:

1. What exactly should be considered when designing the heat pump system without individual room controls? Specifically, I am interested in where it makes the most sense to install an indoor sensor. My understanding is that we need one for controlling the heat pump. Are there other points we should be aware of?

2. The heat pump can also actively cool. We would like to use the cooling function in summer as well. What should be taken into account here? Does each heating circuit require a condensation sensor? And does the heat pump automatically switch to cooling when it detects that the room temperature is significantly above the set temperature?

Finally, if we do decide to include individual room controls, which models would you recommend that support the cooling function but do not cost too much if possible?

I hope the questions are clear and not too "basic."

Thanks in advance for your feedback.
