Maximum Load Adjustment – Continued
7. Press the CHANGE key. The display will begin to flash.
8. Raise or lower the maximum load adjustment using the ▲ or ▼ arrow key. Increasing this
value will increase outlet water temperature, while decreasing it will decrease water
temperature.
9. Press ENTER to save the change. Allow time for the system to stabilize between
adjustments.
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.
4.7 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 4-5. 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 210°F. This switch will shut down and lock out the heater if the water
temperature exceeds 210°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.
