1. AUTOMATIC ENERGY SELECT SWITCH Service Manual Intellitec s Automatic Energy Select Switch AESS is designed to be used in RVs to share the power available from a single circuit breaker between two large loads up to 20 amps The AESS applies power to both appliances until the primary load draws current It then removes power from the secondary load to prevent the circuit breaker from being overloaded This function is particularly useful for sharing power between the microwave oven and another sheddable or postpone able appliances such as the washer dryer or water heater Typically this function was performed with selector switches forcing the owner to manually switch between the two appliances How it works The AUTOMATIC ENERGY SELECT SWITCH AESS senses the current drawn by the primary or on demand load and controls the power to the secondary or shed able load When the power is initially applied and the primary load is drawing less than 3 amps power will be supplied to the secondary load after an initial 45 second delay If the primary load draws more than 3 amps power to the secondary load will be removed and held off until 45 seconds after the primary load is off Servicing the Unit There are no serviceable components in this unit If it is not working replace the entire unit To remove the cover from the unit remove the single hex head screw at the center bottom of the cover Before removing the2. ent of the primary load and utilizes a relay to The secondary load will not operate switch the secondary load if the primary load draws more than 3 amps Possible Cause Solution The secondary load may be turned off Check the switch Problem settings of the secondary load Neither load will operate The AESS is defective Possible Cause Solution The circuit breaker in the distribution box for the loads is tripped Reset the circuit breaker Both loads are turned off Check the switch settings of the loads For further information on this product olease contact Intellitec F In telli Cec www intellitec com AUTOMATIC ENERGY SELECT Pate aoe 042013 SWITCH View with cover removed Figure 1 2 D fa fe rom To Primary Load Current kt Sensor To Secondary Load Equivalent Circuit Neutral Figure 2 Control Electronics F In telli Cec www intellitec com
