  Error Indication or Air Handler Control Switch (RL75e and RL94e only)   
 
When using the Rinnai water heater with an Error Indication Switch, dip 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, dip 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.
