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.
Here are examples for the most common uses. For other
ideas call the toll free Tork Tech Help Line 888-500-4598.

Planning Your Holiday Schedule
Select up to 20 holiday blocks that have a start date and
an end date. Holiday blocks can be anywhere from 1
day in length (the same start and end dates) or up to 364
consecutive days. Holiday blocks must not cross over
December 31st. If a holiday block must run from December
18th through January 5th, two blocks must be entered. One
block from 12/18 to 12/31, and then another from 01/01
to 01/05.
On these dates, the timer will execute the same special
schedule. Enter the holiday schedule in section 5. If no
schedule is entered with a holiday day group in section 5,
On/Off operations will be omitted for the holiday dates.
Astronomic schedule is not affected by holiday dates. The
timer will always execute the sunset/sunrise schedule if
chosen in section 7.
