Remote Controllers- General
The remote controls for the Rinnai Water Heater allow the customer to control the
functions of the water heater and to diagnose certain fault conditions.
Before installing the remote controllers, determine the most convenient location(s).
When deciding on the best location for the remote controllers, consider the
following items:
1) Place the controllers out of reach of small children.
2) Avoid locations where the controller(s) will become hot (over the stove, near
the oven or a radiant heater).
3) Avoid direct sunlight (The digital display can be difficult to read in direct
sunlight).
4) Avoid areas where the remote controller can be splashed with water, oil,
sauce, etc.
5) The remote controller cables carry low voltage, 12VDC digital.
