Installation

The BDR91 is a wireless relay box that can be used to switch valves, pumps, boilers or other heat sources as part of the range of Honeywell 868MHz Radio Frequency (RF) heating controls.

Installation Notes

  • If a new system is being constructed, a BDR91 is added to an existing system, or a faulty unit is being replaced, the desired units must be specially configured to allow them to communicate with each other. This process is called Binding. Please refer to section 3 Binding / Rebinding Procedure.
  • The BDR91 Relay Box will not communicate with other RF products that use different frequencies or communications protocols.
  • The BDR91 Relay Box requires a permanent 230V~ supply.

Installing the BDR91 Relay Box

Honeywell-BDR91-Wireless-Relay-Box-fig-1

  • For best performance, install in an open space. Leave at least 30cm distance from any metal objects including wall boxes and boiler housing. Do not mount on metal wall boxes.

EMC compliance considerations

  • Keep AC mains supply/load cables separate from signal wiring.
  • Refer to Code of Practice standards EN61000-5-1 and -2 for guidance.

Binding/Rebinding Procedure

The binding operation shown is required if any of the system components are replaced or new product added to the system.

IMPORTANT: As the BDR91 can be used with a number of wireless products a typical procedure for the DT92 is shown, for other components refer to their instructions or follow the on screen instructions.

 

Position the unit to be paired close to the BDR91 (remove from wall if already installed)
