10. Repeat steps 5 through 9 as needed until the temperature is stabilized 2 to 3 degrees below the unit’s
setpoint.
If the outlet temperature does not maintain setpoint after a reasonable amount of time and adjustment,
contact your local AERCO representative.
NOTE:
After performing Temperature Calibration and prior to placing the water heater into
service, be sure to set the Outlet Feedback option in the Tuning Menu back to ON.
4.6 OVER-TEMPERATURE LIMIT SWITCHES
The unit contains both automatic and manual reset over-temperature limit switches. These switches are
mounted on a plate as shown in Figure 4-4. The switches can be accessed by opening the front panel
door of the unit. The manual reset switch is not adjustable and is permanently fixed at 200°F. This switch
will shut down and lock out the heater if the water temperature exceeds 200°F. Following an over-
temperature condition, it must be manually reset by pressing the RESET button before the heater can be
restarted. The automatic reset over-temperature switch is adjustable and allows the unit to restart, once
the temperature drops below its temperature setting. Set the automatic over-temperature switch to the
desired setting.
