SLEEP SELECTION -6…7 1 0 (
NOT SEL
)
Defines the control for the PID sleep function.
0 =
NOT SEL
– Disables the PID sleep control function.
1 =
DI
1 – Defines digital input
DI
1 as the control for the PID sleep function.
• Activating the digital input activates the sleep function.
• De-activating the digital input restores PID control.
2…6 =
DI
2…
DI
6 – Defines digital input
DI
2…
DI
6 as the control for the PID sleep function.
• See
