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-volt/24-volt output signals from the
thermostats. The XW Auto Generator Start will start the generator in
response to these signals. Thermostats can not be programmed using the
XW Auto Generator Start.
For specific information about thermostat wiring and where XW Auto
Generator 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-volt/24-volt input used to assure that
the XW Auto Generator 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, or carbon monoxide detector) that produces an active
high 12-volt or 24-volt output.
