Thermostat Leads
(refer to Fig 6-1 for system wiring
information)
•
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 Hurricane
®
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.
See Section 8, Fig 8-6 for zone board jumper
location
6.5 What NOT to Do
Never
shut off the Hurricane
®
Chinook Heating System power via
an inline battery or master switch while the system is running.
Never disconnect the battery when the Hurricane
®
Chinook Heating
System is running, and never disconnect the battery while the
inverter is charging. Do not wire the Hurricane
®
Chinook Heating
System through a disconnect switch that is used as a normal shut-
down of the DC system.
Doing any of the above will severely damage the Hurricane
®
Chinook Heating System because it will fail 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.
