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

Costs around 1200 euros for you, but you do have active cooling.

A software update is not included – it is an additional component. I find that very disappointing from Vaillant...

Active cooling? Not that I know of... Cooling has no submenu options.
Have you tried the active one yet?

Every Flexotherm unit has active cooling – and you have one 😀.

Of course, this must be activated on the professional level both in the heat pump and in the control panel. Additionally, the unit must be installed in a living space.

Currently, the cooling is not working for me. The heating technician and Vaillant have been informed, and I am waiting for feedback. Hopefully, they can connect remotely...

We haven’t even unpacked the Irgendwas 700 control unit yet, since we didn’t have a network for a long time. I need to take care of that and, to be sure, call the heating engineer again. Thank you for the tip.

Huh? Why network? That’s connected with just two wires...?

How did you set everything up? You have to do it through that— or are you talking about the VR900 device for communicating with the Internet?

I meant the 900, of course, sorry.
I think I will really have to contact the heating engineer again. Cooling definitely has no adjustment options. Neither in the 700 nor in the control unit to the left (both at a professional installer level).
