Resetting The Oasis System
To reset the Oasis system, press the exterior reset button
on the face of the Oasis, or turn the burner switch o ff , then
back on inside the coach. The reset will clear faults such
as Low Voltage, Flame Out, or a Low Fluid Level switch
fault, which typically clears on its own when the fluid
level becomes su ffi cient. The Oasis will try to start twice
when there is a Flame Out fault. When it fails to start the
second time, it will then display a fault on the face of the
Oasis and on the System Diagnostics screen within the
SilverLeaf system (if equipped).
In the event of a fault in the Oasis system, the system
will need to be reset.

COACHES WITH A DOMETIC
THERMOSTAT OR KIB LCD
TOUCHSCREEN PANEL (2A-4.3”)
Set the thermostat zones on “Furnace” mode, and adjust
each interior zone temperature setting as desired. The
separate Oasis System switches must be turned on, and
the water temperature in the Oasis System must be up to
temperature for the basement heat to work.
For more information, please refer to the Thermostat
sub-category or the Climate Control section within
the SilverLeaf Functional Guide in Newgle.
NOTICE
!
COACHES WITH SILVERLEAF
The Oasis System must be turned on from the SilverLeaf
touchscreen, and the water temperature in the Oasis
System must be up to temperature for the basement heat
to work.
Note: The basement heat only works when the furnace
(Oasis System) is activated. It will NOT function if the
Oasis System is o ff and the coach is being heated via the
roof air conditioner heat pumps.
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.

Oasis Basement Heat Exchanger
BASEMENT HEAT CONVECTOR(S)
Coaches with Oasis Hydronic Heating will have a heat
exchanger, dual fans, and a designated thermostat. The
basement heat is activated by a separate fixed thermostat
in the basement area when the compartment temperature
falls below approximately 40 degrees Fahrenheit. If this
happens, the hot antifreeze solution in the Oasis system
will circulate, and the blower will turn on to supply heat in
the basement/water compartment area. The Oasis system
must be turned on and the fluid must be above the low
temperature cutout for heat output.
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 o
ff and on according
to the temperature settings.
The exterior reset or the cycling of the ON/OFF
button inside the coach will not reset the system
if there is a component fault, like a pump or other
internal issues.
IMPORTANT
!
CAUTION
!
Any faults not resettable by cycling the switch or
by the Oasis reset button should be diagnosed and
repaired by a qualified technician.
