The talento 800 controls are one, two and four
channel electronic time switches with 365-day,
7-day and 24-hour programming. The channels are freely programmable with a total of
400 schedules. The load status, time of day,
and date are displayed on a large LCD readout. In addition to conventional On/Off programming, the unit provides a “Pulse” and
“Cycle” function.
Functional Description
The talento 800 time control can be programmed
with a 24-hour, 7-day, or a 365-day schedule (with
individual holidays or holiday/vacation periods.)
This control incorporates a calendar through the
year 2095 and also includes automatic leap year
adjustment. The annual daylight savings/standard
time changes can be programmed to occur automatically each year through 2095.
Please read these operating instructions carefully
so that you will be able to take full advantage of the
functions offered by the talento 800 time control.
TO THE INSTALLER:
1. Read operating instructions carefully.
2. Check the input voltage ratings marked on the
unit to make sure this product is suitable for
your power supply and application.
3. Disconnect power supply prior to installation to
prevent electrical shock.
4. Damage to the relay contacts caused by short
circuiting will void warranty.
5. Wire in accordance with National and Local
electrical code requirements.

a) If possible, power to the electronic time switch
should be supplied from a phase different from
the one supplying power to the load.
b) INDUCTIVE-LOADS should have suitable VARIS-
TOR and RC network ( ) across the
supply terminals to reduce voltage spikes.
c) DC INDUCTIVE LOADS should have a diode
across their terminals to eliminate back EMF of
the inductor.
d) HIGHLY INDUCTIVE LOADS, especially fluores-
cent lights, may require a relay in which case (a)
and (c) apply.
e) IN HIGH LIGHTNING AREAS,a surge suppres-
sor should be installed.

Installation
MOUNTING
Surface mounting the talento 800 inside a control panel
or enclosure is accomplished with a standard DIN rail.
Place the two protruding guides, which are on the top
of the rear rail cutout slot, over the top lip of the rail;
then snap the bottom into place.
For stand-alone installation use a Grasslin indoor/outdoor enclosure.
The timer module can be removed from the timer housing for programming or change-out purposes.
WIRING
Make certain to connect only to the supply voltage
designated on the unit itself. Warranty will be void if
wrong voltage is applied. Connect wires to the screw
terminals in accordance with the wiring diagram shown
(use 12 to 22 AWG wire).
INSTALLATION CHECKLIST
1. The time switch should have its own independent
circuit for power supply.
2. Since all electronic instruments are sensitive to voltage spikes, close attention must be paid to the following:

LCD DISPLAY ELEMENTS
The LCD incorporates a number of different elements to display various data and information.
A new feature of the talento 800 Series is the “Sleep”
Mode, an energy saving feature. This feature turns
off the LCD (when the unit is not powered) if no buttons are pressed for a period of two minutes. When
in the sleep mode the only character displayed is a
flashing Colon ( : ). To restore the full display simply
press the clock ( ) button one time.
BLOCK NUMBERS
Block numbers 00 through 99 are automatically
issued during programming. They cannot be
assigned or changed by the programmer. Switching
commands without a date assignment always
receive the block number 00 (priority 0 is always
assigned to block 00 – this cannot be changed). All
switching commands with a date assignment
receive block numbers from 01 to 99. These are
issued in ascending order.
Execution of Programs
At beginning of each day the microprocessor determines
which of the stored programs for that day have the highest priority. Only the highest priority program(s) will be
executed.
Once the talento 800 is programmed, it will automatically
“look back” and assume the correct ON or OFF switch
position.
PRIORITY
Switching commands with a single date or date range
assignment can be issued different priorities (priority 0 and
block 00 is always assigned to switching commands without a date or date range – this cannot be changed). Priority
2 is issued automatically if you start programming by entering a single date. Priority 1 is issued automatically if you
start programming by entering a date range. In either case,
the priority can be changed between 1 and 9 by pressing
the “priority” button during programming. Programs with a
higher number priority will be executed first
PROGRAM STORAGE CAPACITY
The talento 800 can store up to 400 programs. To view the
number of unused or “free” programs available, press the
“Prog.” button twice (3 times from the sleep mode). Every
“Date” or “Date Range” entered and each unique “On” or
“Off” command uses one program position. In other
words, each time the “Prog.” button is pushed a storage
position is used. An “On” or “Off” command assigned to
multiple days and/or multiple channels only utilizes one
program position. Therefore, an “On” event at 7:00 AM
Monday or 7:00 AM Monday through Friday uses only
one program position. Likewise, if it was assigned to two,
three or four channels it would still only constitute one
program.

MANUAL OVERRIDE
Each channel can be manually overridden by pressing
the appropriate “Hand switch”. There are two types of
manual overrides: “temporary” and “fixed”. A “temporary” override is in effect until the next programmed
switch command, at which point the automatic mode
takes over. A “fixed” override lasts indefinitely and
must be canceled by the user. The LCD displays the
operating mode of each channel as follows:
= Automatic “ON”
= Automatic “OFF”
=Temporary “ON”
=Temporary “OFF”
FIX = Fixed “ON”
FIX = Fixed “OFF”
PROGRAM REVIEW/EDIT/DELETE
With the full display in view:
1. Press the “Prog.” button once; a free program location is displayed.
2. Press the “Prog.” button a second time, the number
of free blocks and memory locations are displayed.
3. Press the “Prog.” button a third time, a free program
location is again displayed – additional programs
can be entered as described in the appropriate programming section.
4. Press the “Prog.” button a fourth time, the first program of the “Block” is displayed.
5. Continue pressing the “Prog.” button to review additional programs, one event at a time. To enter the
next “Block”, press and hold the “Prog.” button for
one (1) second. Review the events in the block by
pressing the “Prog.” button. When finished, press
the clock ( ) button one time to return to the operating mode.
6. To edit a particular command, scroll to its location
and change (or add) data as is done during a normal programming procedure – press the “Prog.”
button to store the change. When finished, press the
clock ( ) button one time to return to the operating
mode.
7. To delete a particular command, scroll to its location
and press the “Clear” button. Continue pressing the
“Prog.” button to view additional programs or press
the clock ( ) button to return to the operating
mode.
8. To delete all switching commands; press the “Prog.”
button until the number of free blocks and memory
locations are displayed. Press the “Clear” button
once, “cl” flashes in the display. Press the “Clear”
button until the display shows:
“Fr 99”
400
All switching commands are now cleared.
Press the clock ( ) button to return to the “Run”
mode.
BATTERY-POWERED RESERVE
In the event of a power failure, the built-in Lithium battery maintains the current time and date for up to 6
years. The switch program schedule is stored in EEPROM memory and is non-volatile.
NOTE:
If the display shows Er01, the battery must be
replaced as follows:
1. Remove control module
2. Remove battery casing
3. Remove battery
4. Installation is the reverse of removal
