Argument

"AUTO" returns the relays to normal automatic operation (power-on default). That is, the
limits control the relays.
If the argument n is a numeric value, the relays are forced to manual control and the
value is used to drive the relays.

Relay 1      Value                        Relay 3            Value
OFF                0.                             OFF                   0.
