SECTION 4 –
APPLIANCES AND SYSTEMS
NOTE: If low voltage occurs, the Hydronic
Heating System will shut down. Once the
voltage level is restored, you must reset
the system by turning OFF the diesel
burner switch on the interior control
switch panel for approximately 30
seconds, then turning the switch back
ON.
Hot Water
The Hydronic Heating System allows water to
be heated as it is being used. A continuous supply
of hot water is obtained through a tankless, on-
demand hot water system.
Interior Heat
This system is also equipped with circulation
pumps, which allow individual interior heating
zones. Whenever the room thermostat calls for
heat, the water heating solution is circulated
through interior heat exchangers (similar to
radiators) located throughout your RV that
distributes heat quietly and evenly.

Zone 1 - Main Living Area
•
Zone 2 - Bedroom and Bath(s)
•
Zone 3 - Basement
NOTICE
When the water system is in use, the
thermostat should never be set below 40-
degrees F. to prevent freeze damage to
components.
Exterior Electronic Controller
• Red and green lights indicate the status of your
Hydronic Heating System. See manufacturer’s
operating manual for further information.
Expansion Fill Tank
• Check antifreeze/water heating solution
level monthly. When the system is at
maximum operating temperature (i.e.
immediately after the diesel burner cycles
OFF), the fluid level should be at the level
marked HOT.
• If fluid level is low, see the Maintenance
Section in the manufacturer’s operating
manual for replenishing the antifreeze/
water heating solution.
NOTE: Use only Aqua-Hot
®
approved
propylene glycol-based
antifreeze.
