1. Run two 16 Gauge Wires, Red for (+) and Black for (-), from each particular Heating
Zone’s Heat Exchanger(s) to the Aqua-Hot’s Electronic Controller.
NOTE:
For heating zones with multiple Heat Exchangers (e.g., Living
Room/Kitchen/Heating Loop 1, etc.), run two wires from the closest Heat
Exchanger to the Aqua-Hot’s Electronic Controller and then wire the other Heat
Exchangers in-parallel; reference Figure 9 and Appendix A.
2. Label the wires indicating the heating zone they pertain to (e.g., Living Room/
Kitchen, Bedroom, Fresh Water Tank, etc.)
3. Insert all Heat Exchanger wires into the appropriate terminal/heating zone location
on the Electronic Controller (e.g., “#3 FAN +/#3 FAN -,” for the Fresh Water Tank
Heating Zone, etc.); reference Appendix A.
4. Connect all Electronic Controller “FAN” wires to the positive and negative leads of
each Heat Exchanger; reference Figure 9 and Appendix A.

Mounting Locations for Interior Room Thermostats Overview
The mounting locations for the Interior Thermostats and/or the Electronic Thermostat’s
Temperature Sensors should be selected carefully to ensure even-heat distribution
throughout each heating zone.
A. Locate each Thermostat at approximately chest level, if applicable.
NOTE:
Do not mount the thermostat where it can be affected by:
- drafts or dead spots behind doors and in corners
- hot or cold air from ducts
- radiant heat from the sun or appliances
- heat from concealed pipes and chimneys
- unheated (uncooled) areas such as an outside wall behind the thermostat

Wiring the Interior Room Thermostats
1. Run two 16 Gauge wires from each interior room thermostat 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 all interior room thermostat wires into the appropriate terminal/heating zone
location on the Electronic Controller; reference Appendix A.
3. Connect all wires to the appropriate leads of each room thermostat.
NOTE:
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
Aqua-Hot’s Electronic Controller (i.e., THERM O”). This will ensure that the
Thermostat/Electronic Controller is properly
fuse protected.
4. Permanently mount all interior room thermostats in place.
5. Be sure to turn
OFF
all interior room thermostats at this time.
