3.18 Mounting the Fresh Water Tank Thermostat Overview
The mounting location of the Bay Thermostat should be selected carefully to ensure
even-heat distribution throughout the Bay compartment. The Low-Temp Thermostat is
specifically designed as a means of preventing the domestic hot water from freezing;
therefore, it has a maximum temperature setting of 50°F.
A. Centralize the Low-Temp Thermostat in the Fresh Water Tank storage compartment.
NOTES:
1.
Only the “Bulb” of the Low-Temp Thermostat needs to be physically mounted in
the area requiring heat; reference Figure 21.
2.
Do not mount the Thermostat “Bulb” in a drafty area.
3.
The selected Thermostat body mounting location should allow for easy operator
access; reference Figure 21.

Wiring the Fresh Water Tank Thermostat
1. Run two 16 Gauge wires from the Bay Thermostat’s mounting location to the
Aqua-Hot’s Electronic Controller.
NOTE:
Be sure to use the wire colors illustrated in Appendix A. This will ensure
installation consistency, differentiate the separate Heating Zones, and assist
Service Personnel with troubleshooting.
2. Insert both Thermostat wires into the appropriate terminal/heating zone location on
the Electronic Controller; reference Appendix A.
3. Connect both wires to the appropriate leads of the Low-Temp Thermostat; reference
Figure 21.
4. Permanently mount the Low-Temp Thermostat in place; reference Figure 21.
