Error Indication or Air Handler Control
Switch (RV53i)
When using the Rinnai water heater with an Error Indication Switch, switch No. 4 in the bank of 8 switches should
be in the off position. This is the default position.
To connect the water heater to the Rinnai Air Handler, the Control Switch is necessary to function as the electrical
connection. When the Control Switch is functioning as the electrical connection between the water heater and air
handler, switch No. 4 in the bank of 8 switches should be in the on position.
The Error Indication Switch and the Rinnai Air Handler Control Switch are optional products available from Rinnai.
Installation instructions are included with these products.
