**Note: the heaters’ actual temperature rises are limited by their thermostatic controls. The theoretical values shown above are only for
comparison purposes.
After the 60 seconds in step 4, the display will show the temperature setpoint. See
The heater is commissioned at this point. Faucet can be turned off and used as
needed.
Note: the temperature display will turn off after 5 minutes of inactivity. Display turns
on when water flows through heater.
NON-THERMOSTATIC TANKLESS ELECTRIC WATER HEATERS
The InfoCue™ will flash rapidly while water flows through the unit. Maintain flow.
After 15 seconds, the InfoCue will turn solid red and there will be an audible click.
The heater is commissioned at this point. The faucet can be turned off and used as
needed.
Note: with no flow, the unit will flash every 4 seconds, indicating normal stand-by
mode.
