Hydronic Heating; Oasis Zones - NewMar Super Star Owner's Manual

Hydronic Heating

Hydronic Zone Heating systems make climate control simple and effective.
Oasis Hydronic Heating Operation
This article provides basic operation instructions for the Oasis Hydronic Heating (Floor Heat) system. For your comfort,
your coach may be equipped with the Oasis heating system. This system uses a "boiler" and a pump to heat and
recirculate hot fluid through a series of convectors placed strategically throughout your unit. Fans located on the
convectors provide circulation of the warmed air for more even, efficient heating.
How Hydronic Heating Works
Hydronic central heating is the use of a heat generator
commonly called a boiler (or furnace) to raise the
temperature of a heating medium, generally water
or water and glycol mixture. The heated fluid is then
circulated from the boiler through pipes to heat emitters
such as passive radiators, convectors and underfloor
heating coils, through the interior of the motorhome,
and domestic hot water heat exchanger. The fluid loses
its heat through this circulation and the cooler fluid then
returns to the boiler for reheating.
WARNING
!
Never attempt to modify this furnace. Fire, explosion,
asphyxiation, or carbon monoxide poisoning may
occur. If the furnace malfunctions, consult a trained
service technician.
The Oasis system uses two different sources for heat.
The primary heat source for the Oasis system, and most
efficient, is the diesel burner, which uses diesel fuel from
the fuel tank to burn and create heat. The output of the
diesel burner is 50,000 BTU's, select double shower
floorplans may be equipped with the 85,000 BTU model.
The second heat source is an electric heating element. It
is important to note the difference in the two systems. The
electric heating elements have two 5,000 BTU heating
elements and should be used only to help maintain the
temperature once the diesel burner has brought the
system up to proper operating heat levels. From a cold
start, the 5,000 watt electrical heating elements will not
operate the system alone.
Domestic Hot Water

hydronic heating, refer to Newgle.

Oasis Zones

For heating, your unit is divided into three "zones" on
your thermostat or your climate screen, if your coach is
equipped with the SilverLeaf system. The "Furnace" mode
will appear in all four zones, but only three are active.

ZONE 1 - DASH, LIVING ROOM, AND
KITCHEN CONVECTORS
These convectors are located under the dash and
kitchen cabinets, and control heat in the cockpit, living
room, and kitchen areas. The dash mounted convector
is the only one in your unit that has a two speed fan. The
switch controlling the fan speed is located in the front
overhead cabinet adjacent to the diesel boiler switch.
ZONE 2 - MIDDLE AC AND HEAT PUMP
ZONE 3 - BATHROOM CONVECTORS
These convectors are located in the bathroom cabinetry
and stool room. The fan switch for the stool room
(marked "HEAT") must be in the "ON" position to provide
heat in the stool room. In order to receive heat in the
Stool Room, a "rear" zone (bathroom or bedroom areas)
must be chosen on your thermostat or your climate
screen, if your coach is equipped with the SilverLeaf
system.
ZONE 4 - BEDROOM CONVECTORS
These convectors are located throughout the cabinetry
and walls of the rear bedroom area. To activate the Oasis
heating system, select your heat source, either diesel
or electric, using the switches in the front overhead
cabinet or through the SilverLeaf system. Once you have
selected a heat source (diesel or electric), and the boiler
is operational, set thermostat for the desired zones.
The system will turn convector fans off and on according
to the temperature settings.
IMPORTANT
!
The Oasis 'diesel burner' heat source provides
approximately 50,000 BTU's of heat, and is designed
to start and operate the system at full capacity. The
electrical heating element provides approximately
5000 BTU's of heat.
