7.0 Using an AGS Module
Info:
If the temperature start feature is not needed, ensure this
setting is set to the
OFF
position.
• Set Gen Run Temp Time
– This menu sets the amount of time the
generator runs after a temperature autostart.
Default setting:
Set Gen Run Temp Time = 2.0 Hrs
Range:
0.5-25.5 Hrs
When the temperature around the remote temp sensor (per the
METER: 03D
AGS Temp
display) increases to the
Gen Run Temp Start
setting, the genera-
tor immediately starts and runs based on the
Gen Run Temp Time
setting.
When this run time period is
fi
nished, the temp sensor reading is checked.
If the temperature sensor (or thermostat control if using the optional pigtail
adapter) reading is below the
Gen Run Temp Start
setting, the generator
will autostop. If the temperature sensor (or thermostat control) reading is
above the
Gen Run Temp Start
setting, the generator will continue to run for
a second run time period. At the end of this second run time period, the tem-
perature sensor reading (or thermostat control) is checked again. This cycle
continues as long as the
CTRL: 03 Gen Control
menu is set to
AUTO
, or the
SETUP: 04F Max Gen Run Time
setting is reached, whichever occurs
fi
rst.
Why should I use Gen Run Temp?
Typically, in a mobile application such
as in an RV or on a boat where the air conditioning (A/C) unit is too much
power for the inverter to run from the batteries, this feature is used to start
a generator to run the A/C unit. Many RV and marine customers travel with
pets and they do not want to leave the pets inside on a hot day. With this
feature, you could set the A/C unit to turn on and leave. Whenever the inside
temperature rises to the start setting, the generator autostarts to provide
power to the A/C unit. This would keep the area cool and comfortable—plus,
while the generator is on, the inverter batteries are being charged.
Where should I set Gen Run Temp Start?
If using this feature to power
an A/C unit, the
Gen Run Temp Start
setting should be slightly above the
temperature setting of the thermostat controlling the air conditioner unit.
Once the
Gen Run Temp Start
setting is reached, the gen starts providing
power to the A/C unit. The reason the
Gen Run Temp Start
is set above the
A/C unit’s thermostat setting is to ensure the A/C unit runs when the genera-
tor starts. If the
Gen Run Temp Start
setting is below that of the A/C unit’s
thermostat setting, the generator runs but the A/C unit is not calling for a
run period or cooling. In other words, your generator is running but the pow-
er is not being used by the A/C unit—resulting in wasted fuel and run time.
Info:
If using the temperature autostart feature to start a genera-
tor that is powering two air conditioners, it is suggested that the
second air conditioner’s thermostat be set 2° to 5° higher than
the
fi
rst air conditioner. This staggered setting allows the
fi
rst air
conditioner to start and run in an effort to keep the coach cool. If
the temperature continues to rise inside the coach, the second air
conditioner turns on.
How long should I set the Gen Run Temp Time?
When using the tem-
perature autostart feature, the generator autostarts and runs until the
Gen
Run Temp Time
setting or the
SETUP: 04F Max Gen Run Time
setting is
reached, whichever occurs
fi
rst. This means you could set the time to the
lowest time setting (
0.5 Hrs
), knowing the generator will attempt to run until
the temperature setting is met.
