NOTE:
To enable switching loads of a voltage different than the timer
power voltage, the outputs from this timer are isolated relay contacts. You
need to connect a source of power to the common (COM) terminals as
shown above. Do not mix solid and stranded wires under the same
terminal.

WARNING:
Timer power supply voltage must be 24 VAC 60 Hz
only. Refer to Special Instructions if any load voltages are greater
than 24 volts.
