Fresh Water Tank Thermostat Location:
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 26.
Do not mount the thermostat bulb in a drafty area.
The selected mounting location should allow for easy
operator access. Reference Figure 26.
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

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

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 27.
