Hazards.

Can cause severe injury, death, or equipment damage.

Do not set the operating limits of the control outside of those listed by the appliance manufacturer.

Figure 18 - AquaSmart Keypad

To ensure smooth appliance operation, the AquaSmart requires a separation between the High and Low limits no less than the greater differential plus 5°F. For example: If the HIGH LIMIT is set to 180°F, the HIGH DIFF to 20°F, and the LOW DIFF to 10°F, the control will not allow a LOW LIMIT above 155°F (180°F - 20°F [the greater of the two differentials] - 5°F = 155°F).

A. Temperature High Limit

1.In any mode or screen other than an OPTION sub- menu, press the “HIGH LIMIT” key.

2.The following screen will be displayed:

The temperature displayed is the current setting. Use the ▲ and ▼ keys to select the desired setting. Tap the button to increase or decrease the temperature by 1°, or hold it to increase or decrease the temperature by 5° at a time. The control will not allow you to select out-of-range values.

3.Press the “ENTER (RESET)” key.

4.The control will ask you to confirm the setting with

B. Temperature Low Limit

1.In any mode or screen other than an OPTION sub- menu, press the “LOW LIMIT” key.

2.The following screen will be displayed:

The temperature displayed is the current setting. Use the “▲” and “▼” keys to select the desired setting. Tap the button to increase or decrease the temperature by 1°, or hold it to increase or decrease the temperature by 5° at a time. The control will not allow you to select out-of-range values. For cold-start operation, turn the low limit off by pressing the down arrow key repeatedly until OFF is displayed.

IMPORTANT: To prevent flue gas condensation and reduce fatigue caused by thermal cycling on conventional (non-condensing) boilers, the LOW LIMIT set point should be 150° F or above.

NOTE: Appliance manufacturer’s temperature requirements supersede this recommendation.
