ENGO ETR-868 Wireless Relay Transmitter & Receiver Kit

The ENGO ETR-868 EngoLink wireless relay kit connects heating controls to a boiler, circulation pump or other compatible device where running a control cable is impractical. Supplied with a factory-paired transmitter and receiver, it provides wireless on/off switching over 868 MHz.

Key Features

• Wireless heating control: Ideal for retrofit installations and linking a wiring centre to a heat source or pump.
• Ready-paired kit: Transmitter and receiver are paired at the factory.
• Volt-free output: Receiver uses COM/NO relay contacts for compatible control circuits.
• Compact installation: Each module measures 46 × 46 × 24 mm and can fit in an installation box or mount on a DIN rail using the included brackets.
• Status indicators: LEDs show device operation.
• Power-loss shutdown signal: The transmitter's built-in supercapacitor allows it to send an OFF command when its power supply is disconnected.
