▪ H.USINGRECIRCULATIONMODES–STEP1
The following section explains and details the use of the Internal / External Recirculation Modes.
Preheat or Internal Recirculation Modes – When calls for hot water are satised, the water heater is factory
programmed to Preheat and automatically maintain the temperature set point of the water heater – 24 hours a
day, 7 days a week. The differential setting can be adjusted to control the temperature set point.
Internal Recirculation Mode allows the installer to program specific recirculation functions by day and
time to circulate and heat water more efciently - when the user most needs hot water. See Recirculation
Functions, this manual, for details.
External Recirculation Mode – This mode keeps an external recirculation loop warm to make hot water
production more efcient and also aid in freeze protection. An external recirculation line must be installed
in order to recirculate water externally. The installer may program specic recirculation functions by day
and time to circulate and heat water when the user most needs hot water. See Recirculation Functions, this
manual, for details.
To set Recirculation Modes:
1. Installer Mode will activate when is pressed and held for ve seconds while the water heater display
is powered Off.
2. Turn the dial to 6:RC. Press the Dial button . “oFF” will ash when the 6:RC setting is ready to be
changed.
3. Turn the dial to “oFF” to turn off the Recirculation Pump, or “on” to turn the Recirculation Pump on.
Press the dial button to select the setting and return to the Installer Mode.
