Board

Multi-Pin Connectors

The Zone Control Board has four multi-pin connectors, see Figure
9-3: Plumbing for Five Zones Using the Distribution Module
, that
are to be connected through connector cords (supplied) to the

matching multi-pin connectors as follows:

10 pin connector to Heating Module Remote Operating

Panel.

8 pin connector to Heating Module (connector cord

transitions to a 9 pin connector for the Heating Module).

12 pin connector to Distribution Module (connector cord

transitions to a 9 pin connector for the Distribution Module).

14 pin connector to thermostat and cabin fan connector

plug.

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.
