The hot water temperature controller is a handy and convenient feature which allows you to pre-set your desired hot water temperature within different areas of your home.

This eliminates the need of constantly fiddling with your hot and cold taps to reach your preferred water temperature and keep it consistent. Another feature of the Rinnai hot water temperature controllers is that they provide a handy self-diagnostic tool should there be a fault with your Rinnai tankless hot water heater. A Rinnai error code will flash on the controller’s digital monitor, allowing for prompt troubleshooting.

If you have a Rinnai continuous flow hot water heater that does not have a water temperature controller installed there are still steps you can take to try and troubleshoot any faults with the unit – even without a temperature controller showing precisely what the issue is.
