A passive air/water heat pump

[MoreT]

came across the Jifon AirGo http://www.jifon.se/eng/enindex.html
they are using a indoor temperature sensor to control the heat pump
similar to air/air, anybody knowing if it works?

Are you affiliated with the company? Just looks like an advertisement to me.
