Receiver for wireless controllers of the RT SR868 series

Universal receiver for wireless heating control

The SR868 receiver is a key element of a wireless heating control system, designed to work with RT series and 091FLRFV2 controllers. The device allows remote switching of heating circuits, providing comfort and energy savings. It is particularly useful in electrical installations where traditional wiring is difficult or impossible.

Installation and application

The SR868 relay is designed for direct mounting in a mounting box or wall socket, making it easy to integrate with existing infrastructure. Thanks to radio communication at a frequency of 868 MHz, it provides a stable and interference-resistant signal. Connection to the controller is wireless, eliminating the need to run additional wires. If the connection with the controller is lost, the device goes into manual mode, ensuring the continuity of the system. An LED indicates the current operating status of the receiver.

Compatibility and specifications

The SR868 receiver works with controllers from the STANDARD series: 091FLRFv2(TX), RT310TX and RT510TX, as well as models RT310RF, RT510RF+ and RT305RF. It is primarily intended for controlling electric heating, but can also be used in other applications requiring remote switching of a load up to 16A. The receiver is powered by two AA (alkaline) batteries, providing independence from the power grid. The output signal is a NO/COM contact (voltage-free), allowing control of various types of heating devices.

• Radio signal: 868 MHz – guarantees stable communication and minimizes interference.
• Load: Maximum load 16A – allows control of most standard heating devices.
• Mounting: Possibility of mounting in a mounting box or wall socket – provides installation flexibility.
• LED indicator: Indicates the current state of the device – facilitates diagnostics and system monitoring.
• Power supply: 2x AA alkaline batteries - provides independence from mains power.
