Operating Instructions
talento 400 Series
24-Hour, 7-Day, One and Two Circuit
Electronic Time Controls
The talento 400 controls are one or two channel electronic time switches with 24-hour or 7day programming. The channels are freely programmable with a total of 30 (model 471) or 40
(model 472) schedules. The load status, time
of day, and day are displayed on a LCD readout. In addition to conventional On/Off programming, the unit provides a “Pulse” and
“Cycle” function.

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.
Shortest Switching Time: One second
5. Wire in accordance with National and Local
electrical code requirements.
Installation
WIRING
MOUNTING
Surface mounting the talento 400 inside a control panel
or enclosure is accomplished with a standard DIN rail.
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.
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.
2. Since all electronic instruments are sensitive to voltage spikes, close attention must be paid to the following:
For stand-alone installation use a Grasslin indoor/outdoor enclosure.
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 VARISTOR 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 fluorescent lights, may require a relay in which case (a)
and (c) apply.
e) IN HIGH LIGHTNING AREAS, a surge suppressor should be installed.

*Recessed buttons—use a long pen point or pencil
LCD DISPLAY ELEMENTS
The LCD incorporates a number of different elements to display various data and information.
A new feature of the talento 400 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 (

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”
6. After a free (blank) program location is viewed, an
additional press of the “Prog.” button will display the
free (unused) program locations – displayed as “Fr
XX” where “XX” represents the number of unused
locations.
7. To delete all switching commands; press the “Prog.”
button until “Fr XX” is displayed. Press the “Clear”
button once, “Cl” is displayed. Press the “Clear” button again. “Cl” flashes and “Fr 30” or “Fr 40” is displayed. All switching commands are now cleared.
Press the clock (
mode.
) button to return to the “Run”
= Temporary “ON”
BATTERY-POWERED RESERVE
= Temporary “OFF”
In the event of a power failure, the built-in Lithium battery maintains the current time and date for up to 3
years. The program schedule is stored in EEPROM
memory and is non-volatile.
FIX
= Fixed “ON”
FIX
= Fixed “OFF”
PROGRAM REVIEW/EDIT/DELETE
With the full display in view:
1. Press the “Prog.” button once; the first program is
displayed.
2. Continue pressing the “Prog.” button to review additional programs, one event at a time.
3. 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.
4. 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.
5. After the last programmed event is viewed, an additional press of the program button will display a free
(blank) program location. Additional programs can
