NOTES: Use this wiring with figure 6.5 for grounded AC power.
LRA and LRB load resistors for triac feedback are 2K ohm, 15 watt resistors
If auxiliary solenoids are not used, replace with 2K ohm, 15 watt resistors.
Each solenoid or relay coil should draw at least 60mA.
Connect one MOV between 3L1 and 3L2 for electrical noise suppression.
Connect one MOV to the 3L1 side of each solenoid load and to 3L2 for electrical noise suppression.
