2. Safety information 3
GB
Installation must be carried out and inspected by a specialist or
under his supervision.
For assembly:
• Suitable for use in ambient conditions with normal
contamination levels
• Use the appropriate Grässlin accessories for wall
surface-mounting.
If correctly installed in accordance with VDE 0100, Part 40,
the parts with which contact is still possible can be regarded
as double-insulated (protection class II).
For operation:
• We place high demands on the EMC interference resistance of
the electronics when developing our products. The interference
immunity achieved significantly exceeds the currently valid
requirements of the appropriate EN standards.
• In individual cases, check whether additional protection
measures are still necessary, e.g. the installation of appropriate
components (varistor, suppresser diode, RC element).
• In extreme cases, it is recommended to install another module,
e.g. isolating relay or switching contacter, mains interference
suppresser filter.
For operation:
• No metallic pointed objects (e.g. needles) may be used on keys
pressed with a tool.
Important:
• Only safety extra-low voltage may be connected for operating
the clock with safety extra-low voltage.
• When operating the clock with function extra-low voltage, either
the mains voltage (230 V AC) or function extra-low voltage may
be connected. In these cases, it is not permissible to connect
safety extra-low voltage.

6.1 Block numbers
Block numbers are automatically issued during programming.
There are block numbers from 00 ....... 99 (note block principle).
All switching commands without date assignment always receive
the block number 00. (Priority 0 is always assigned to the
block number 00 – it cannot be changed).
All switching commands with date assignment receive the block
numbers from 01 ..... 99.
These are issued in ascending order.
6.2 Priority
Switching commands with a date assignment can be occupied
with different priorities.
If you start with a date when entering the program, a new block
number and priority 2 are always offered.
The priority can be changed between 1 and 9,
(see Section 10).
The switching command with a higher priority is
executed first.
6.3 Saving the switching program
In the current operating state (colon flashing), the time switch
offers the possibility of using the entered switching program
with the function:
•Back Up – can be saved in “background“
•Restore – restores to the foreground
•Change – 2 switching program alternately
GB

6. General 8
Back Up
with the key Prog and 1(Day key)
The switching program in the
foreground is preserved and can be
changed as required.
If necessary, call up the original
switching program again with the
Restore function.
Restore
with the key Prog and 7(Day key)
The switching program in the
foreground can be changed as required.
The saved and the current switching
programs can be used alternately
with the Change function.
Change

6.4 Programming at the desk
The control section can be
removed and programming
can be conveniently
performed at the desk.
6.5
Programming with the talento taxxi (manual programming unit)
The talento taxxi offers the most convenient method for
transferring the switching programs.
6.5.1
From time switch to time switch (from control section to control
section – without mains voltage!). The switching programs
are read out from one time switch and are transferred to
the next one – see the talento taxxi operating instructions.
Note: If the data is not correctly transferred, the error
message Er 02 appears in the display of the
time switch.
• Check the time switch type
A switching program can only be transferred
to a time switch of the same type.
• Transfer the program again.
There may be a read/wire error.

6. General 10
6.5.2 Compile your switching programs on a PC with the
software talento dialog. They are then transferred to
the taxxi via the PC interface.
With the taxxi, the switching programs are now
transferred to the relevant time switch (control section)
via the infrared interface. Refer to the talento dialog
manual.
Note: Software and accessories can be ordered separately:
•talento taxxi set Art.No.: 07.01.0029.1
consisting of:
• Software talento dialog, including manual
• talento taxxi (manual programming unit)
• Cable 1:1 for the serial interface

6.6 Service
6.6.1 Error messages
The time switch signals malfunctions:
•Er 04 – in the event of incorrect access to
the EEProm. This error message can appear in
individual cases. Press any key and the time
switch will continue to run normally.
If this error message appears often, we recommend
that the time switch be replaced.
Consult your dealer.
•Er 02 – in the event of incorrect transfer via the
IR interface.
Transfer the program again.
There may be read/write errors.
•Er 01 – If the battery voltage is too low.

If the battery voltage falls to below a value which
does not guarantee functioning of the time switch
(error message Er 01) , replace the battery.

article number 09.02.0007.8.
Replacing the battery:
• Remove the control section, see 6.4
• Remove the battery casing
• Carefully remove the connector
• Insert a new battery
• Carefully insert the connector
• Replace the battery casing
