sensor (or thermostat control) reading is above the AGS: 04 Start Temp F
setting, the generator will continue to run for a second run time period. At
the end of this second run time period, the temperature sensor reading (or
thermostat control) is checked again. This cycle continues as long as the
AGS: 01 AGS Control menu is set to Enable (or Enable w/QT).
If the temperature autostart feature is not needed, set to the OFF position.
• 65F - 95F – This setting determines the rising temperature value that
will trigger a generator autostart.
• Ext Input – This setting is used when an optional AGS adapter (PT1 or
PT2) is used. When an AGS adapter is connected to the AGS’s REMOTE
port, an external command from a thermostat connection on an A/C
control unit causes the generator to start. See the ME-PT1 or ME-PT2
instruction sheets for info on pigtail adapters. (See 08 AGS TECH: Temp)
Default setting: StartTemp = OFF
Range: OFF, Ext Input, 65F - 95F (5 deg. increments)
Why should I use Start Temp? Typically, in a mobile application (RV or
boat) where the A/C unit is too much power for the inverter to run from the
batteries, this feature is used to start the generator to run an A/C unit. Many
RV and marine customers travel with pets and do not want them to be at risk
from dangerous inside temperatures if they are away from the coach/boat.
With this feature, you can set the A/C to turn on and then leave. If the inside
temperature rises to the start setting, the generator automatically starts to
provide power to the A/C unit. This keeps the area cool and comfortable—
plus, while the generator is on, the inverter batteries are being charged.
Where should I set Start Temp? If you are using this feature to power
an air conditioning unit, the AGS: 04 Start Temp F setting should be slightly
above the A/C unit’s thermostat “cool” temperature (usually around 70-72F).
Once the temperature setting is reached, the generator will start providing
power to the A/C unit. The reason the temperature is set above the A/C
unit’s thermostat is to ensure the A/C unit will run when the generator starts.
If the AGS’s temperature setting is below that of the air conditioning unit’s
thermostat setting, the generator will run, but the A/C unit is not calling for
a run period or cooling; your generator is running, but the power is not being
used by the A/C unit—resulting in wasted fuel and run time.
Info: If using temperature autostart to start a generator that is
powering two A/C units, it is suggested that the second A/C unit’s
thermostat be set 2° to 5° higher than the fi rst A/C unit. This stag-
gered setting will allow the fi rst A/C unit to start and run in an effort
to keep the coach cool. If the temperature continues to rise inside
the coach, the second A/C unit will turn on to further cool the coach.
AGS: 05 Start Volts Menu
This menu allows you to set and enable a battery voltage value that causes
the generator to automatically start. Starting the generator on voltage is the
most common method of autostarting the generator—it is considered the
simplest and easiest to understand. When the battery voltage (on Terminals
#3 & #4) decreases to or below this setting for two continuous minutes,
the generator will automatically start and run based on the AGS: 03 Run
Time Hour setting. If the DC voltage start feature is not needed, ensure this
setting is set to the OFF position.
Default setting: Start VDC = 11.0 VDC (12v), 22.0 VDC (24v), 44.0
VDC (48v)
Range: 10.0-12.2 VDC (12v), 20.0-24.4 VDC (24v), 40.0-48.8 VDC (48v)
