Check with Rinnai to see if the old remotes are compatible with the new heater. Might mean upgrading the remotes too but the wires should be OK. Double check that he has actually connected the wires to the heater. Rinnai in Australia recentyl changed the connection point for the wiring. I can help further with this if this is the issue (not sure where you are!)
