TEMPERATURE CONTROL – DELUXE 
15 
Adjusting the Volume of the Voice Prompt and Operating Tone 
The volume of the voice prompt and the operating tone can be adjusted to a level comfortable for you. The 
volume of the voice prompt and the operating tone can be adjusted independently of each other. The volume 
levels on a Deluxe controller are adjusted independently of another Deluxe controller. 
The voice prompt and / or operating tone can also be turned off on an individual or all Deluxe controllers so 
they do not sound at all. 
The factory default volume setting of both the voice prompt and operating tone is medium [med]. If there is 
an interruption to the water heater power supply, the volume of both the voice prompt and operating tone 
returns to the default setting. 
When adjusting the volume levels, the operating tone volume level is indicated by a chime, followed by the 
voice prompt volume level which is indicated by two beeps. If during the volume setting procedure only the 
chime is audible, this indicates the voice prompt is off. If during the volume setting procedure only the two 
beeps is audible, this indicates the operating tone is off. 
To adjust or turn off the volume for the voice prompt and operating tone: 
•  Turn off all Deluxe controllers. 
•  Press and hold the up (i) button, then within four (4) seconds press the ON / OFF button. 
Each press of the ON / OFF button will change the voice prompt and operating tone in the following 
sequence: 
  operating tone [MAX], voice prompt [OFF] 
  operating tone [MIN], voice prompt [MIN] 
  operating tone [MIN], voice prompt [OFF] 
  operating tone [OFF], voice prompt [OFF] 
  operating tone [MAX], voice prompt [MAX] 
  operating tone [MED], voice prompt [OFF] 
  operating tone [MED], voice prompt [MED] 
This order then repeats. 
Note: If the ON / OFF button is not pressed within four (4) seconds of the up (i) button being pressed, 
“CL” will start flashing on the temperature display panel. If this occurs, release the up (i) button  and 
recommence the procedure.

bathroom, a voice prompt will sound on all Deluxe controllers to notify others that assistance is required.

can be activated during any operation.

The voice prompt will sound on all Deluxe controllers, 
“assistance required, assistance required” 
The red light in the assistance call button will glow on all 
Deluxe controllers for the duration of the voice prompt.
