Control-R™ - What is the difference between factory reset and power cycle?
Factory Reset Defined:
Factory Reset restores the module back to its factory default values. Factory resetting also erases all current settings and wireless network history.
A Factory Reset must be performed when changing wireless networks (you must factory reset first, and then select the new network). A Factory Reset must also be performed when starting over on the pairing process (you must factory reset first, and then start the pairing process).
How To Factory Reset - Press and hold the Connect button (see below) on the module until the LED blinks WHITE, and then release. The module will reboot and the module LED turns RED when complete.
Power Cycle Defined:
Power Cycle shuts down power to the module and then restarts power (which is the same function as removing the water heater plug from the power outlet and then plugging it back into the outlet). When trying to connect or disconnect power to the tankless water heater, Rinnai recommends using the water heater power plug instead of using the Reset feature on the module. If you are ever required to use the Reset feature on the module, insert a small pin into the Reset opening (see below).
