Appendix C: Electronic Controller Features
Secondary 12 Volt-DC Battery Connection:
The electronic controller is equipped with two 12 Volt-DC
power source connections, which allow for a secondary 12
Volt-DC battery connection. This 12 Volt-DC battery connec-
tion is a product-safety feature that should be utilized whenever
the Aqua-Hot’s main 12 Volt-DC power supply is connected to
a battery disconnect switch. This feature will ensure that the
Aqua-Hot will be protected in the event that the primary power
is interrupted while the Diesel-Burner is operating (e.g., during a
burn-cycle). This secondary 12 Volt-DC battery connection will
ensure completion of the required 3-minute “purge cycle” of the
Aqua-Hot’s diesel-burner.
NOTE: This illustration details the proper wiring requirements for the usage of the
battery disconnect switch feature. If connecting the optional battery
disconnect wire, the jumper connecting the terminals on the electronic
controller must be removed.

Terminals Strips with Screw-Type Fasteners:
The electronic controller utilizes terminal strips/plugs that are
equipped with screw-type fasteners, which are molded directly
into the terminal strip/plug, itself. This will ensure a positive
mechanical connection between the electronic controller and all
wire harnesses attached to it.
