8.0 Using the ME-RC Remote
temperature sensor (or thermostat control – if using the optional pigtail
adapter) reading is below the AGS: 04 Start Temp F setting, the generator
will autostop. If the temperature 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, ensure this setting is set
to the Off position.
•
65F - 95F – These settings determine 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 more information on pigtail adapters.
Default setting: Start Temp = 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 air conditioning
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.
Whenever 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 the temperature autostart feature 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
staggered setting will allow the fi rst A/C unit to start and run in an ef-
fort 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.
