Wireless head is used to control radiator heating. An excellent replacement for the traditional manual thermostatic head. For proper operation of the TRV head, it is necessary to associate it with the E20 master controller. Two-way communication and temperature comparison system provides a sense of comfort throughout the heated area, not just near the radiator. Up to 6 TRV heads can be paired with one controller in the same room.
