Figure 1 - Getting to know the AquaSmart 7600 Series Control
OEM Installation: When replacing an OEM-installed
AquaSmart, consult the appliance manufacturer’s wiring
diagrams and instructions for additional information.
Retrofit Installation: The AquaSmart can be used to
replace most standard boiler temperature controls. For a
cross-reference of compatible replacements, refer to
Owner’s Manual.
There are two basic methods for mounting the AquaSmart
to the boiler.
Sensor/Immersion Well Mounting – This is the
most common method. If the existing well is not
suitable for any reason, a standard design aftermarket
immersion well with the proper dimensions can be
purchased from a HVAC distributor. The AquaSmart
can then be mounted in the typical way.
Surface Mounting – This is sometimes required
and is part of the AquaSmart base design. The base
has adequate clearance built-in to accommodate the
temperature sensor lead exiting the back of the
control. A 48” extension cable (Pt. No. 52120) can
be purchased separately for applications where
needed.

B. Temperature Low Limit
In any mode or screen other than an OPTION sub-
menu, press the “LOW LIMIT” key.
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. 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: Boiler manufacturer’s temperature
requirements supersede this recommendation.
Press the “ENTER (RESET)” key. Confirm the
setting by pressing “ENTER (RESET)” again if the
value is correct, or “CANCEL (BACK)” if it is not.
C. Temperature High Limit Differential
In any mode or screen other than an OPTION sub-
menu, press the “HIGH DIFF” key.
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.
Press the
“ENTER (RESET)” key. Confirm the
setting by pressing “ENTER (RESET)” again if the
value is correct, or “CANCEL (BACK)” if it is not.
D. Temperature Low Limit Differential
In any mode or screen other than an OPTION sub-
menu, press the “LOW DIFF” key.
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.
Press the
“ENTER (RESET)” key. Confirm the
setting by pressing “ENTER (RESET)” again if the
value is correct, or “CANCEL (BACK)” if it is not.

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
In any mode or screen other than an OPTION sub-
menu, press the “HIGH LIMIT” key.
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.
Press the
“ENTER (RESET)” key. Confirm the
setting by pressing “ENTER (RESET)” again if the
value is correct, or “CANCEL (BACK)” if it is not.
