Chinook Heating System
6.4 Wiring The Zone Control Board
·
Primary 12 VDC power to the Zone Control Board should
originate after the master disconnect switch from a dedicated
connection on the house battery bank.
·
A 25 amp fuse or breaker must be included inline from the
power source to the positive connection on the Zone Control
Board. The primary power wire gauge must be sized to
permit no more than a 3% voltage drop from the power
supply to the Zone Control Board.
·
The Oasis
®
Chinook and the Remote Operating Panel are
connected to the Zone Control Board through the electrical
connections located at the bottom of the Zone Control Board.
·
The Zone Control Board connects to the thermostats and
cabin fans through a 14 pin plug, with butt connect leads.
Cabin Fan leads
·
The positive (red) lead from each cabin fan is to be attached
to one of the trailing cabin fan leads, color coded for zones,
from the thermostat and cabin fan connector plug.
·
The negative lead from each cabin fan is to be attached to a
ground terminal (not provided) that is connected to a battery
ground.
·
The cabin fan 1 leads (orange) can supply up to a maximum
of 10 Amps. The other cabin fan leads 2-5 can supply up to a
maximum of 5 Amps each. The total current draw is not to
exceed 18 Amps for all cabin fan leads.
·
If the system requires higher amperage draws, install a
separate relay to power the fans. This relay will use the
existing fan circuit as a signal and must be wired to a
secondary power source (not the heater’s control board). See
Figure 5-3.
