7.5 Setting the date and time
The MEC2 contains a radio receiver that under normal reception conditions
constantly monitors and corrects the control unit time switch.
When using the MEC2 programming unit, the reception of the radio clock
signal depends on location and position.
Reception of the radio clock signal is indicated by symbol
on the display.
Normally, reception is possible within a radius of 1500 kilometers around
Frankfurt/Main [Germany].
In case of reception problems, please observe the following:
– The radio reception is weaker in rooms surrounded by steel-reinforced walls,
cellars, high-rise buildings etc.
– The distance from sources of interference, such as computer monitors and
TV sets, should be at least 1.5 m.
– The radio reception tends to be better at night than during the day.
You can manually adjust the date and time on the MEC2 if the radio clock signal
is not available in your area.
USER INFORMATION
Date and time are preset at the factory.
This function is safeguarded through battery backup, i.e. independent of the
mains power supply.
USER INFORMATION
We recommend leaving the radio clock receiver disabled outside Germany
to prevent the reception of false signals (incorrect time setting).
USER INFORMATION
Well screened boiler rooms may impede the reception of the radio signal. If the
radio clock signal reception is impaired or non-existent, retain the automatic
factory setting according to calendar for summer/winter time adjustment.
