Hi

I've rencently bought Honeywell evo home kit and it came with a BDR91 relay. I would like to get a conformation that the wiring im going to do is correct

Existing: ESI ESRTP4RF+ (connected as shown below)

New : BDR91 [connection diagram from my understanding]

Yes, appears correct. That green/yellow wire needs brown sleeving or insulation tape though
