Connecting the thermostats (optional)
Wires 1, 2, 3, and 4 on the wiring harness can be connected to two
thermostats. Wires 1 (yellow) and 2 (gray) are intended for thermostat 1
and wires 3 (orange) and 4 (gray) are intended for thermostat 2.
These wires connect to 12/24 V output signals from the thermostats. You
can enable the Auto Gen Start to start the generator in response to these
signals. You cannot program your thermostats with the Auto Gen Start.
For specific information about thermostat wiring and where Auto Gen
Start connections should be made, please consult your thermostat
documentation or contact the thermostat manufacturer.
Connecting an external shutdown (optional)
The external shutdown input is a 12/24V input used to assure that the
Auto Gen Start keeps the generator off under conditions that may be
potentially hazardous. Wire 5 (white/black) and 6 (gray) on the wiring
harness are intended for an external switch or sensor (such as a moisture
detector, carbon monoxide detector or coach running signal) that
produces an active high 12V or 24V output.
Connecting an external manual on/off switch (optional)
The external manual on/off inputs (wires 7 and 8 on the wiring harness)
are intended for wiring to one or more remote on/off switches for starting
and stopping the generator manually. The other contact of the switch
should be connected to ground. In order for the Auto Gen Start to be able
to detect these switches, you must wire the positive of the generator
battery to the constant 12V/24V generator battery positive (wire 10 on the
Auto Gen Start wiring harness). See Figure 2-12.
