Section 3: Thermostats
Fresh Water Tank Thermostat Locations:
Select a location that will ensure even-heat distribution
throughout the fresh water storage tank bay com-
partment in order to prevent the domestic water and
plumbing system from freezing.
Typically only the bulb of the thermostat needs to be
physically mounted in the area requiring heat (usually in
close proximity to the domestic water pump). Refer-
ence Figure 27.
Do not mount the thermostat bulb in a drafty area.
The selected mounting location should allow for easy
operator access. Reference Figure 27.
Avoid mounting the fresh water tank thermostat’s bulb
too close to the bay heat exchanger.
Fresh Water Tank Thermostat Mounting:
1.
Determine a location for the thermostat based upon
the previous location information.
2.
Once the thermostat has been completely wired,
permanently mount the thermostat in place. Reference
Figure 27.

Fresh Water Tank Thermostat Wiring:
1. Run two 18-gauge wires from the thermostat’s mount-
ing location to the Aqua-Hot’s electronic controller.
NOTE: It is recommended that the wire numbers in Appendix
A be used when installing the Aqua-Hot in order to
assist with differentiating between the separate heating
zones and to aid service personnel with troubleshoot-
ing.
2. Insert each thermostat wire into the appropriate termi-
nal/heating zone location in the electronic controller.
Reference Appendix A and Figure 28.
3. Connect both wires to the appropriate leads of the
thermostat. Reference Figure 27.
