I needed a system that would reliably maintain communicatiin between the existing three heating manifolds in the house and the new air source heat pump buffer tank pump that was being installed. With guidance from Edward in the Tech team, I took a decision to invest in three RF Transmitters and one RF Receiver for an outlay of £280. Edward was very helpful, and he talked my electrician through the pairing process and since then, the system has functioned flawlessly. I am very pleased with the equipment and Tech support in the RF Solutions team.
