11 AquaSmart Boiler Control Manual
Installing the AquaSmart Control
(Refer back to Figure 3 for appropriate mounting method).
Mounting to the Immersion Well or 2-in-1 Sensor:
1. Mount the control by aligning the 7/8” diameter hole
(found on back) around the mating feature of the
immersion well or 2-in-1 sensor and press into
place. Position the control upright and tighten down
the #10 screw located on the left side of the control.
Tighten so that control is securely in place ( Figure 9) .
2. Plug the temperature sensor lead terminal into the
receptacle on the control base. See Figure 10.
Mounting to Appliance Surface:
1. Use the AquaSmart mounting template to locate the
mounting holes in a desired location on mounting
surface. The template can be found in the back of
this manual.
2. Use (3) #8 x 3/4” self drilling screws (.110 hole
diameter if pre-drilling) included in the installation
kit. Run screws into mounting surface, leaving a
1/4” space between bottom of screw head and
mounting surface.
3. Open the cover of the AquaSmart control to expose
key hole locations in plastic case. Align key holes
over mounting screws and secure in place.
4. Plug the temperature sensor lead terminal into the
receptacle on the control base. See Figure 10.
5. If necessary, use the 48” cable extension to connect
sensor to control base. Refer back to Figure 3.

Hazards
This control must be installed, adjusted and
put into operation only by a trained, licensed,
qualified professional or service agency in
accordance with the latest revision of the
National Electric Code ANSI/NFPA 70 (Canada
CSA C22.1) state, local codes and authorities
having jurisdiction.
y Follow the appliance manufacturer’s wiring
diagrams and note all safety controls.
y Typical safety controls include high temperature or
pressure limits, low water cutoffs, anti-scald valves,
pressure relief valves and water feed valves.
y Verify all limits and safety controls are installed and
functioning correctly, as specified by the appliance
manufacturer, applicable safety standards, codes
and all authorities having jurisdiction.
y Provide ground wiring to the appliance, burner and
controls.
Electrical Shock Hazard.
Can Cause Severe Injury,
Death, or Equipment Damage.
Disconnect power before wiring to prevent
electrical shock or equipment damage.
y All wiring must comply with local electrical codes
and ordinances. The limits given in the
specifications section must not be exceeded when
applying this control. Terminals on the AquaSmart
are approved for copper wire only.
y Refer to the label on the inside of the AquaSmart door
or to Technical Specifications in this manual for
Electrical ratings and maximum load information. Use
manufacturer instructions when wiring controlled
equipment or refer to typical hookups in Figure 12
through Figure 17.
y More than one service switch may be needed to
disconnect all power to the AquaSmart. The optional
power disconnect switch interrupts power to the
AquaSmart control. Depending on system wiring,
some terminals and connections (most notably ZR
and the input to the optional power disconnect switch)
may still be live.
