Sorry Ken I worked for Rinnai Australia as a service manager so treat my advice with a little cuation but you should find the basic universal controller should work fine. The code over here is a MC-91 Q2A. It will MC-91 sometihing for over there (I'm guessing from the codes you use you are across the pacific!). You can wire this unit either back to the heater or to wiring from another controller, just match the colours and link them in. Power off the heater first but it is all low voltage.

Go to the link below page 18 to 27 will tell you how to hook up the remote. The electrician should be the one that hooks it up. I woul ask him to hook it up for you.

Error code 12 can sometimes be caused by a short circuit on the low voltage side of the installation. Could possibly be a fault with the controller itself which is low voltage.

Here is a link for one on ebay. Looks like you need to go to the Rinnai web site and contact one of their authorized dealers/service providers in your area. Doesn't look good in cutting out the middleman on this one. Hope this helps you out.

The manual says:
http://www.coinwash.com/temp/rinnai.pdf

"For the name of the Authorized Distributor or Installer nearest you, please contact your local HVAC dealer or gas service technician, visit the Rinnai website (www.rinnai.us), call Rinnai at1-800-621-9419 or write to Rinnai, 103 International Drive, Peachtree City, Georgia 30269"

Manual says that the remote is for setting temperature.
When you turn on hot water spigot, tankless water heater will heat the water to the set point temperature.
If water heater is not set up to use remote, then tankless unit will heat to 140 degrees F.
"With the MCC-45-4US remote control installed the water temperature is adjustable from 96
to 180°F. The water temperature cannot be set to a temperature other than 140°F
without the use of the MCC-45-4US remote control unit. If you require a temperature
other than 140°F you must install the MCC-45-4US remote control unit."

"Error messages are displayed on the remote control units, simplifying service calls."

Page 9 of manual shows hot to set temperature using remote.
Water taps must be shut off to set temperature.
Circulating pump must be turned off.
"Simply press the H or C button until desired temperature is displayed"
"green in-use indicator will display"

If your unit is not working, the manual says to contact local plumber.
Fixya has specialists who will talk to you by phone about your problem for a fee.

Run through the basic checks

• Power lead from the heater plugged in a socket turned on.
• Gas on to house
• All valves below heater in on position.
• If they have controllers in the house turn on (key pads marked with Rinnai logo in kitchen or bathrooms usually)

There is a turbine that spins in the heater when a hot tap is run. If the heater has been sat for some time not operating the turbine might have stuck. Run the hot tap and keep it running, using a hammer give the centre pipe connection under the heater a firm hit a few times(not too hard). This might unstick the turbine.

Centre tap of the rinnai will turn off hot water supply only.
Easiest way is to turn off your mains water supply. This will isolate both hot and cold, no need to turn off anything else

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!)

make sure you have a good connection between the remote and the unit
