A smart way to control external heat sources
Connected to a Y series control system, in.grid acts as a dispatcher of external heating sources such as your heat pump, your central house heating system or your gas heater. You can also connect up to five single-button in.k110 switches to control your accessories.
 
Enjoy energy savings
With in.grid, take full advantage of your external heat sources to optimize your savings, depending on your external heating system and your climate. Choose one of the four modes that suits you best.
 
Connect up to five single-button switches
Two in.grid models are available, based on your needs: five single-button in.k110 switches or four in.k110 switches and a CO port. The CO port is used to connect any accessories in your system’s communication chain.
