Thermostat Leads
·
The power lead to the thermostat should be fused (1 Amp)
and attached to a power terminal (not provided) that is
connected to the battery.
·
The return lead from each thermostat is to be attached to
one of the trailing thermostat leads, color coded for zones,
from the thermostat and cabin fan 14 pin connector plug on
the zone control board.
·
The Oasis
®
Chinook has a single space heating loop. The
"series" jumper on the zone board (below the bypass
jumper, to the left of the largest relay on the board) must be
put in place. If the "series" jumper is not put in place, then
the thermostats calling for heat in zones 3, 4, and 5 will not
activate the Heat Loop 1 pump, which is the only space
heating pump in this system. This will result in cold air
blowing from the fans when only zones 3, 4, or 5 are calling
for heat.
·
When the "series" jumper is not in place, the zone control
board uses Heating Loop 1 to supply coolant to Zones 1 and
2, and uses Heating Loop 2 to supply coolant to Zones 3, 4,
and 5. Zones 1 and 2 are calling for heat, the zone control
board will activate the Heat Loop 1 pump. When Zones 3, 4,
and 5 are calling for heat, the zone control board will
activate the Heat Loop 2 pump.
6.5 What NOT to Do
Never shut off the Oasis
®
Chinook Heating System power via an
inline battery or master switch while the system is running. Never
disconnect the battery when the Oasis
®
Chinook Heating System is
running, and never disconnect the battery while the inverter is
charging. Do not wire the Oasis
®
Chinook Heating System through
a disconnect that is used as a normal shut-down of the DC system.
Doing either will severely damage the Oasis
®
Chinook Heating
System because it fails to automatically purge the combustion
chamber. Such damage is detectable upon inspection and will not
be covered under warranty. Always shut the system off using the
normal system controls, after it has completed its purge and cooled
down the combustion chamber.
