## Summary description

Honeywell BDR91A1000 is a relay (switching) module designed for integration with the evohome heating control system. It provides a 5 A switching output to control boiler or zone equipment within a smart heating setup. The module enables reliable on/off switching driven by evohome controllers and is suitable for residential and light-commercial applications requiring centralised heating control.

## Long description

The Honeywell BDR91A1000 relay module is designed for integration with the evohome heating control system and provides a single 5 A switching output. Intended to act as an interface between evohome controllers and a boiler or zone equipment, this compact module enables centralised on/off control of heating devices in residential and light-commercial installations. The module supports reliable switching actions in response to evohome schedules and commands, allowing the heating system to operate according to programmed temperature setpoints.
Advantages
The relay module offers a straightforward method to add a dedicated switching channel to an evohome system, delivering a clear 5 A switching rating suitable for many domestic boilers, pumps and valve actuators. Its compatibility with evohome ensures coordinated operation with thermostats and schedules, reducing manual intervention. The module’s compact size and simple wiring reduce installation complexity and help keep control panels tidy.
Suitable for
Centralised on/off control of residential boilers and heating zones
Switching small circulator pumps or zone valves within an evohome setup
Light-commercial heating systems with moderate switching current requirements
Retrofit projects where an evohome-compatible relay channel is needed
When it may not be suitable
This relay module is rated for a maximum switching current of 5 A and is therefore not suitable for directly driving high-current equipment or large commercial boilers that require higher switching capacities. For applications needing multiple independent channels, higher current ratings, or specialized safety interlocks, a different relay array or contactor with appropriate ratings should be used. Electric heating elements or motors with inrush currents exceeding the module’s specifications should not be connected directly.
Key specifications
Switching output: single relay channel with 5 A maximum switching current
Function: on/off switching controlled by evohome heating controllers
Intended installation: central heating control panels or near boiler equipment
Compatibility: designed for use within Honeywell evohome heating control systems
How to use
Install the module in accordance with evohome installation guidelines and local electrical regulations. Connect the relay module between the evohome controller output and the boiler or zone device input, ensuring correct polarity and secure terminal connections. Configure the evohome controller to recognise the relay output and assign it to the appropriate heating zone or boiler control function. Verify operation by testing on/off commands from the evohome interface and check that all safety and interlock circuits remain functional after integration.
What to consider before purchase
Ensure the 5 A switching rating is sufficient for the boiler, pump or actuator to be controlled
Confirm compatibility with your existing evohome controller model and wiring layout
Check local electrical codes and whether a qualified installer is required for safe installation
Assess whether additional channels or higher-current switching devices are needed for the installation
Usage recommendations
Use the relay module as a dedicated on/off interface within an evohome system for low- to moderate-current heating equipment. For reliable long-term operation, arrange installation by a certified installer, include appropriate fusing or overload protection, and avoid connecting loads with high inrush currents directly to the module.
