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

Where is the cooling water supposed to come from? I hope you have taken this into account and haven’t fallen for empty sales talk.

He has a heat pump that can both heat and cool. When cooling, cold air is blown over the outdoor unit instead of warm air.

Why ramble? We planned the air-to-water heat pump from the beginning, I just later came across the possibility of also being able to cool within certain limits.

Basically, you would only need to invert the signal from the thermostats.

As far as I know, reversible air-to-water heat pumps can provide cooling by reversing the heat pump’s operating principle. That means instead of extracting heat from the outside air and transferring it indoors, heat is removed from the indoor air and released to the outside air.

However, this does not mean that the outdoor unit simply blows cold air instead of warm air. Where would the outdoor unit get cold air from in the summer? 🙂

Exactly. An air conditioner is also a heat pump.
