CHECKOUT
Inspect all wiring connections at the controller terminals,
and verify compliance with the installation wiring
diagrams.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring
or making wiring connections, to prevent electrical
shock or equipment damage.
If any wiring changes are required, first be sure to remove
power from the controller before starting work. Pay
particular attention to verifying the power connection
(24, 120, or 240 Vac).
After the controller is mounted and wired, apply power.
Power Loss
The date and time settings are retained for 24 hours after
a power outage. After a power loss of more than 24 hours,
the date and time settings may need to be reentered. All
other settings are stored permanently.
