Auto Generator Start (AGS) Compressor Time Delay On RV’s equipped with an optional AGS Kit, the vehicle generator will automatically start when any zone calls for cooling and will shut off when zones reach set point. The Auto Generator Start (AGS) function will be implemented by an individual power module board configured for this function by setting the GEN Start DIP switch ON. On the AGS power module board a relay shall be used to provide a start signal to the generator.

Some preventative measures taken by the occupants of the RV can reduce the heat gain and improve the performance of the air conditioner. During extremely high outdoor temperatures, the heat gain of the vehicle may be reduced by: 1. Parking the RV in a shaded area. 2. Using window shades (blinds and/or curtains). 3.
