Maintenance; Change Time-Date - MetaSystem VESTHA THS501 Manuel D'utilisation

2.13. Maintenance

The alarm system does not require "special measures" as it is the unit itself that automatically checks the
status of the devices connected to it, indicating any anomalies. Periodically check on the unit if there are any
indications of anomalies.
Periodically test functioning of the devices without the vitality transmission function or those devices where it
has been disabled.
At least once a year run functional tests to check the condition of the internal backup batteries of the 230V
powered devices: disconnect mains voltage and provoke a system alarm checking that the devices are working
properly.

2.14. Change Time-Date

The unit has an internal clock for managing events and recording them in the events memory (Log-Book). To
change the date and time (which are factory set however) proceed as follows:
• With the unit disabled press and hold down the two keys P> and <P simultaneously until the message
PROGRAMMING OK? appears.
• Select the MODIFY TIME-DATE? menu with the P> or <P key.
• Press OK and then enter the code (default 1111).
• Press OK to confirm and the message SET TIME appears on the display: hh.mm.ss.
• Set the time by entering the numbers and going to Hours, Minutes and Seconds with the P> or <P key.
• Once the time is set, press OK and the message SET DATE appears: dd.mm. yy, then enter the Date with
the same method used for the time.
• Confirm with OK to save the new settings and exit the menu automatically.
• Press Del to return to the main menu.
Replacing the internal clock battery
If the date and time is not working or late, the 3V lithium battery needs replacing (mod CR2032) which is
in the back of the unit under the connectors' plastic protection.
Follow the instructions carefully to replace it:
• Switch the unit off and disconnect the 220V mains power.
• Lever the tip of a screwdriver in the notch on the side of the battery and take the battery out (see Fig.2)
• Now put the new battery in paying attention to polarity ("+" upwards)
• Reconnect mains power (the unit turns back on)
• Now access the above mentioned menu and set the date and time.
