Oasis Hydronic Heating System Operation (Model: Chinook)
This article provides an operational overview of an Oasis Hydronic Heating System (Model: Chinook).
Overview
The Oasis® Chinook Heating System uses a 50,000
BTU (true output) diesel burner (12 VDC) controlled by
a multi-functional electronic controller as the primary
source of heating coolant fluid (anti-freeze and water).
Two 1500 Watt, 120 VAC immersion elements are used as
secondary heat sources to provide an additional 10,000
BTU of heat.
The Oasis® Chinook Heating System heats the coolant
fluid to provide a source of heat for all hydronic space
heating needs. Through the use of its integral distribution
pumps, the Oasis® Chinook Heating System has the
ability to circulate the coolant fluid to all space heating
areas. It can also provide a supply of potable hot
water using the integral heat exchanger. The Oasis®
also incorporates engine heat and preheat (optional)
functions.
Operating Instructions
TURNING THE POWER TO THE OASIS
CHINOOK HEATING SYSTEM ON
The Oasis® Chinook Heating System’s main Control
Panel, located on the front of the heater, contains three
push buttons: ON/OFF power, Bypass, and Reset. The
power switch must be pushed ON (power LED will turn
ON) to turn the DC electrical power to the main control
board ON and is required to be left ON whenever heat is
required.
The Zone Control board (Figure 8-4) will be powered
whenever the master disconnect switch is ON. The
master disconnect switch must be left ON whenever heat
is required.
When the Oasis® Chinook Heating System is shut
down for any extended period or the season, it is
recommended that the power switch and the battery
master disconnect switch be turned OFF.
ACTIVATING THE BURNER (PRIMARY
HEAT SOURCE)
The burner switch on the Remote Operating Panel
controls the ON/OFF of the diesel burner (primary heat
source). When the burner switch is turned ON, the diesel
portion of the Oasis® Chinook will turn ON after ten
seconds. The Burner LED will turn ON when the diesel
burner has been activated. The burner will continue to
operate until the coolant in the Oasis® Chinook reaches
cycling temperature. At this point, the diesel burner will
turn OFF.
If the Oasis® Chinook Heating System coolant should
cool down below this temperature range, the burner
will again commence firing and will continue until either
the burner switch on the remote panel is turned OFF
or cycling temperature is again achieved. If the burner
switch on the remote panel is turned OFF, or cycling
temperature is achieved, the burner stops and the Oasis®
Chinook enters a two minute cool down stage prior to
completely shutting down.
ACTIVATING THE AC HEAT
(SUPPLEMENTAL)
Place the AC power switch on the Remote Operating
Panel to either the one element or two element position.
The AC Heat (green) LED will turn ON indicating the
AC element(s) are energized and the coolant is being
electrically heated. The elements will continue to operate
until the coolant in the Oasis® Chinook reaches cycling
temperature. At this point, the elements and the AC heat
LED will turn OFF.
If the Oasis® Chinook Heating System coolant should
cool down below this temperature range, the AC
element(s) will again be energized and will continue until
either the AC switch on the remote panel is placed in the
OFF position or cycling temperature is again achieved.
If the AC element switch on the remote panel is turned
OFF, or cycling temperature is achieved, the AC elements
are de-energized and the AC Heat (green) LED turns
OFF.
ACTIVATING THE BURNER AND AC
IMMERSION ELEMENT(S) JOINTLY
Turn the burner switch ON and place the AC power
switch on the Remote Operating Panel to either the
one element or two element position. The Burner and
AC Heat (green) LED’s will turn ON indicating the diesel
burner and AC element(s) have been selected.
Use only a non-toxic propylene glycol based coolant
with additives generally recognized as safe ”GRAS”
by the FDA in the Oasis® Chinook Heating System.
