The Honeywell Home Wireless OpenTherm Bridge R8810A1018 is a heating control accessory designed to connect compatible wireless heating controls with OpenTherm-compatible domestic boilers. It supports more precise boiler control by allowing the heat output to respond to changing heating demand.
OpenTherm communication allows the boiler's gas valve and heat output to be controlled according to the demand signal from a compatible control. By helping the boiler reduce its flow temperature to match demand, the system can support lower return temperatures and condensing operation when conditions allow. This makes the Honeywell Home R8810A1018 OpenTherm Bridge a useful component in compatible heating control installations.
Designed for straightforward wiring and simple binding to the appropriate control, this bridge can be used with supported OpenTherm-compatible domestic boilers. It is important to note that it will not communicate with RF products using different frequencies or communication protocols.

Key Features & Benefits
More Precise Boiler Control
OpenTherm communication allows the boiler's heat output to respond to varying demand signals from a compatible heating control.
Supports Condensing Operation
By allowing the flow temperature to be reduced in line with demand, the system can help maintain lower return temperatures and support condensing operation when conditions are suitable.
Easy to Wire
Designed for straightforward wiring into a compatible heating system when installed according to the manufacturer's instructions.
Simple Binding Process
Can be bound to the appropriate compatible control to establish the supported wireless connection.
OpenTherm Boiler Compatibility
Can be used to switch and control compatible domestic boilers through the supported OpenTherm system configuration.
Protocol-Specific Communication
Designed to work with compatible RF controls; it will not communicate with wireless products that use different frequencies or communication protocols.
How OpenTherm Helps Control Heating
Unlike a basic on/off demand signal, OpenTherm allows a compatible controller to communicate changing heating requirements to the boiler. This can help regulate the boiler's heat output and flow temperature rather than simply requesting full heat or no heat.
When the flow temperature is adjusted to suit the heating demand, the return water temperature may remain below the dew point, allowing a compatible condensing boiler to recover more heat from its flue gases. Actual performance depends on the boiler, heating system design, settings and operating conditions.
Who Is This Product For?
The Honeywell Home Wireless OpenTherm Bridge is suitable for heating engineers, installers and customers sourcing an accessory for a compatible wireless heating control system. It is particularly relevant to installations where OpenTherm communication is supported by both the control arrangement and domestic boiler.
Installation & Setup
- Confirm the R8810A1018 stock code and compatibility with the intended heating control system.
- Check that the boiler supports OpenTherm and that the appropriate control uses a compatible RF frequency and communication protocol.
- Wire the bridge according to the manufacturer's instructions.
- Bind the bridge to the appropriate compatible control using the specified pairing procedure.
- Test the connection and heating operation after installation.
Installation must follow the manufacturer's instructions and applicable electrical regulations. Use a suitably qualified heating or electrical professional where required.
