Old stuff...

A BDR91A relay is hard-wired and thus always listening for packets.

A BDR91A can be used as:

  • a boiler relay (responds to a call for heat)
  • a heat valve relay (as used with a combined CH/DHW systems)
  • a relay for an Electric Zone (doesn't call for heat)
  • a relay for a Zone Valve zone (as above, but calls for heat)

Respondable Packets

A BDR91A will respond to a RQ sent to 0008, 0016, 1100, 1FC9, and 3EF1:

095 RQ --- 18:013393 13:237335 --:------ 0008 001 00
060 RP --- 13:237335 18:013393 --:------ 0008 002 000A

095 RQ --- 18:013393 13:237335 --:------ 0016 001 00
059 RP --- 13:237335 18:013393 --:------ 0016 002 0012

095 RQ --- 18:013393 13:237335 --:------ 1100 001 00
055 RP --- 13:237335 18:013393 --:------ 1100 008 000C1400007FFF01

095 RQ --- 18:013393 13:237335 --:------ 3EF1 001 00
055 RP --- 13:237335 18:013393 --:------ 3EF1 007 00017F005300FF

Note that the RQs payload is ignored, and all RPs have a domain_id of 00.

Specifically, BDR91A configured as a boiler relay will respond to a 1FC9 thus (dashes/spaces added to the payload for readability):

095 RQ --- 18:013393 13:237335 --:------ 1FC9 001 00
053 RP --- 13:237335 18:013393 --:------ 1FC9 012 00-3EF0-379F17 00-3B00-379F17

Whilst a BDR91A configured as a DHW valve will respond:

053 RP --- 13:106039 18:013393 --:------ 1FC9 006 00-3EF0-359E37

Note: The boiler relay payload includes a 3B00, whilst the other relays do not.

Only commands up to 4000 have been tested.
