Planning Your Program
EWZ201C two channel mode allows you to set-up different
control logic for each channel. A channel could be sunset to
sunrise while the other channel is sunset to time OFF.
EWZ201C one channel mode allows you to set-up the two
relays as DPST. Both relays turn ON and Off at the same
time. This is useful for switching 208 or 240 volts.
Momentary output mode is used for switching
latching contactors. The installation section describes
how to remove a jumper on the back to set timer
for this mode.
Two SCH events must be used to complete a schedule
for each channel. An event must be entered for ON and
an event for OFF. The event screen will indicate the number
of each event from 01 to 32.
