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.

6.1Block 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.

6.2Priority

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.

6.3Saving 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

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

with the key Prog and 4 (Day key)

Both switching programs can be used, changed and saved independently

of each other.

6.4Programming at the desk

The control section can be removed and programming can be conveniently performed at the desk.

6.5Programming with the talento taxxi (manual programming unit)

The talento taxxi offers the most convenient method for transferring the switching programs.

6.5.1From 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.

	talento taxxi
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.

GB

6. General		10

6.5.2Compile 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

6.6.1Error 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.

6.6.2Lithium battery (service life, type: see Technical data)

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.

Order the battery from your dealer with the 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

7. Factory setting		12

The default values correspond to Central European Time (CET).

The time switch offers 3 operating modes. The date and time and the operating mode AU are set.

Operating modes:

• AU	Automatic switchover
	of the summer time control function, see Section 7.2.1
	The switchover takes place on the legally defined date.
• cHA	Weekday-related switchover
	of the summer time control function, see Section 7.2.2
	You enter the summer time end date valid for your location/
	country.
	e. g. the first Sunday in April of the current year
	(start of summer time)
	the last Sunday in October of the current year
	(the end of summer time)
	In subsequent years, switchover always takes place on the
	right day of the week in the correct calendar week.
• no	No switchover, see Section 7.2.3
