ᐅ Room Thermostats for Heating and Cooling

Hello,

we actually wanted to use our air-to-water heat pump to actively cool through the underfloor heating as well, but unfortunately forgot to inform the electrician about this.

He said we would need room thermostats that allow switching between heating and cooling.

However, the plastering is already done, so the wiring cannot be changed. As a result, we have too few wires for thermostats with a changeover switch.

Is it possible to simply turn the thermostat all the way up and set the heat pump to cooling? Or would that cause problems with condensation on the floor?

Are there any other options?

Best regards,
Daniel

Yes, you also need to activate it in both modules. First, at the heat pump itself under "Cooling Technology," and then also in the 700 unit.

Okay, thanks again! I’ll give it a try this evening.

The question for me would be, even if the water for the underfloor heating could be kept cold, wouldn’t that feel uncomfortable on the feet?
I wouldn’t want to walk barefoot in the basement all day...
Without cooling, the temperature inside the house was about 25°C (77°F) on hot days, and that was fine...

It depends on the floor covering – tiles can definitely be uncomfortable, since I also can’t stand barefoot in one spot for long in the basement.

But that’s just how it is – you have to put on slippers. We’ve had temperatures around 24-25°C (75-77°F) and it was fine – but I still would have liked to try it out.

I'm with Sebastian on this – I'm just curious whether it actually works.
We had around 23-24°C (73-75°F) on the ground floor and up to 25°C (77°F) on the upper floor. It could have been one degree cooler on the upper floor.

If I’ve read that correctly, the “cold” supply water would be around 20°C (68°F) anyway. So it’s not cold enough to cause discomfort.

We had about 23-24°C (73-75°F) on the ground floor and up to 25°C (77°F) upstairs. Upstairs could have been a degree cooler.

Shouldn’t a ventilation system help to “even out” the temperature?
