You can switch either the Hr20 or the H20 to altrernate address. The alternate address is different for each of those models of receiver. The addresses for the Hr20 are 00001 & 00003, where H20 addresses are 00001 & 00002. Even after you switch one of the receivers, the blue light on the front of each receiver will respond to both remotes, but the receiver itself won't.
