See the figure below for the location of the master override. The master override has
three modes of operation:
• Normal - Allows the Control Module and inputs to control the state of the relays
• All ON - Forces all of the relays to the ON state and the Control Module and
inputs can not turn the relays Off
• All OFF - Forces all of the relays to the OFF state and the Control Module and
inputs can not turn the relays On
