Electronic Controller Wiring:
NOTE: Please reference Appendix A for specific wiring
information.
Most electronic controller thermostat and switch
connections possess an "(I)" or an "(O)" symbol.
The "(O)" symbol indicates a positive 12 Volt-DC
output to a particular thermostat or switch, while the
"(I)" symbol indicates a positive 12 Volt-DC input
signal from a particular thermostat or switch. The 12
Volt-DC output signal is always present as long as the
electronic controller is powered by a 12 Volt-DC power
source, while the 12 Volt-DC input signal is only
present whenever a switch is activated or whenever a
thermostat is calling for heat. Reference Appendix A.
All electronic controller fan power connections (and
two switch connections) illustrate a "(+)" or a "(-)"
symbol, which indicates that they are polarity-sensitive.
Therefore, be sure to use care when wiring these
particular components to the electronic controller.
Each heating zone "FAN" circuit can supply up to
2.0 Amps of direct current. This 12 Volt-DC power
source allows for multiple Cozy III heat exchangers
to be wired "in-parallel." Reference Figure 42 and
Appendix A.

section 9: Electronic Controller Wiring
NOTE: A maximum power consumption of 24 Watts can be
supplied by the electronic controller for each "FAN"
heating zone.
Heating Zone 1 is reserved electrically for the "Living
Room/Kitchen Heating Zone" (Heating Loop 1)
ONLY, and Heating Zones 2, 3, and 4 are reserved
electrically for the "Bathroom, Fresh Water Tank, and
Bedroom Heating Zone" (Heating Loop 2) ONLY.
Heating Zone 5 is reserved electrically for the
"Optional Heating Zone" (Heating Loop 1) ONLY.
All switch connections are to be wired directly to the
Aqua-Hot's interior switch panel. Reference Figure
41 and Appendix A. Both the "IND-LT (+) B3" and
the "IND-LT(-) B6" connections on the electronic
controller are reserved electrically ONLY for the
diesel-burner switch indicator light connections.
The Aqua-Hot's electronic controller is designed to
work with most electronic room thermostats; however,
the chosen thermostat must produce a constant 12
Volt-DC output signal and must receive its 12 Volt-
DC power supply from the electronic controller (i.e.,
"THERM-O") in order to ensure that the thermostat
and electronic controller are properly fuse protected.
