Hybrid PLC & RF Communication: Reliable Heat Pump Retrofit in Historic Homes

Zero-Wire Retrofit for Historic Challenges European historic stone and concrete buildings often block wireless signals, making traditional thermostat installation unreliable. The hybrid PLC RF controller uses existing 230V power lines for industrial-grade data transmission, complemented by 868MHz RF for areas with poor wireless coverage. This achieves 100% connectivity without destructive rewiring, reducing labor costs and project risk—an ideal solution for heat pump retrofit historic home projects. As a professional provider of Heat Pump Controllers, we focus on solving the unique challenges of historic building renovations.
