Hi all,
I've got a Rinnai Infinity 24 (REU-2425-W) which is controlled by an existing MC-33-A in the kitchen, and a BC-45 in the bathroom. We're adding an ensuite, so would like to have a controller in there as well. I *think* adding an MC-91 controller should work, but one supplier has said it isn't compatible with the HWS. I'm waiting for Rinnai to get back to me, but was hoping someone here might have an idea.
Cheers!
