• Applicable Model
Install the remote controller according to the instructions in the Installation Guide (p. 58).
• The N-069M-DV can be programmed so that it will default to one of four temperatures if the remote
controller is removed (176, 140, 130, 120
°
F). To change the default temperature, the remote control-
ler must be initially installed, and removed after programming.
* Changing the default temperature setting:
1. Within the first ten minutes of connecting electrical power to the unit, but before pressing the
Power On/Off button, hit the up [ ] or down [ ] button on the remote controller. This will put
the unit into maintenance writer mode. If pressing either of these buttons does not put the unit
into maintenance writer mode, unplug the unit for sixty seconds and try again.
2. The maintenance monitor item number will flash on the display. (the initial item number will be “99”).
3. The up [
] and down [ ] buttons can be used to change the maintenance writer item number.
4. Choose a temperature from the chart below and set the 14 and 15 maintenance writers according to
the chart. Pressing the Flow Meter Alarm Set button for 0.5 seconds will switch the indicated item
number from “OFF” to “ON” or “ON” to “OFF”. If the Priority lamp is flashing when an item number
is displayed, this indicates an “ON” setting for that item number, and if the Priority lamp is off, the
item number is off.
*Do not change the other item numbers. This may cause a fault in the water heater.
5. After setting the 14 and 15 item numbers for the desired temperature, press and hold the up [ ]
and down [ ] buttons together for five seconds to confirm the new settings. The remote control-
ler will emit a tone when the settings are confirmed. If this is not done, the unit will not put the
setting changes into effect. After confirming the setting, remove the remote controller to initiate
the default temperature setting.
Note:The setting changes can be cancelled by pressing the Power On/Off button before confirming the
settings, or if the unit is left alone for ten minutes without confirming the settings. If the default
setting needs to be changed again, disconnect the electrical power to the unit, reconnect it and
follow this procedure again.
