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 you are 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 generator will
start 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 will run
when the generator starts. If the Gen Run Temp Start setting is below that
of the A/C unit’s thermostat setting, the generator will run but the A/C unit
is not calling for a run period or cooling. In other words, 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 the temperature autostart feature to start a generator
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.
• 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 - 6.0 Hrs (0.5 hr increments)
When the temperature around the remote temperature sensor (based on
the METER: 03D AGS Temp display) increases to the Gen Run Temp Start
setting, the generator immediately starts and runs based on the Gen Run
Temp Time setting. When this run time period is fi nished, the temperature
sensor reading is checked. If the temperature sensor (or thermostat con-
trol – 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 temperature 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.
