The EPH TR1 and TR2 RF Transceiver Pack provides a wireless communication solution for managing heating system components where traditional cabling is not feasible. This system facilitates bidirectional signal transmission between two points, allowing for remote switching of boilers, underfloor heating manifolds, and pump overrun systems. Engineered for professional use in both residential and commercial settings, the kit operates on a 230 Vac 50Hz power supply. With a contact rating of 250 Vac 10(3)A, the transceiver units ensure reliable switching performance. This technology supports flexible installation in retrofit projects or locations where wiring infrastructure is restricted, providing a dependable alternative to hard-wired setups.
