Remote temperature controllers are a feature that provides control over the water
temperature. Rinnai Infinity water heaters can be operated with 1, 2, 3, or no
temperature controllers. The Universal controller MC-91-1A comes as standard with all
Infinity water heaters.
NOTE:
Each time a button is pressed, a BEEP will sound.
The BEEP sound can be muted by depressing the Temperature Controller Up and Down
buttons simultaneously for more than 3 seconds.
This can be done for each Temperature Controller.
To return to original settings, repeat this step.
