The Temperature sensor is not included. It is an option.
The programming of the time and temperature display is made by buttons at the computer board or via
remote control.
The digital clock can operate stand-alone with a built in quartz crystal as time reference, as a slave
clock to a master clock transmitting 24 V polarised 1/1 minute impulses or synchronised by TC, DCF
or GPS.
If the DLS-function is set , the clock is changing summer and winter time, the last Sunday in March
and the last Sunday in October automatically.
The clock has adjustable light intensity.
If power failure occurs the display is turned off. The internal clock continues to keep the correct time
for 48 hours. After the power failure the display is turned on and correct time is shown.
