REMARK :
The controller won't work (neither the clock) until the temperature sensor has been connected.
Following very short power interruptions the controller may get locked up. Therefore leave a pause of
about 10 seconds between switching the power off and switching it on again.
First switch the power supply of the controller off.
Connect the sensor output (OUT + and -) with the corresponding points (IN + and -) of the controller.
(don't forget to connect the supply voltage of the sensor!)
ATTENTION:
The power supply of the sensor K6001 MUST be kept apart from
the one of the controller.
NEVER
connect both power supplies together.
Now switch the power supply of the controller on. This causes the indication FAIL to be redisplayed.
By now pushing SELECT repeatedly, you can call the different indications onto the display one after another.
The different time and alarm settings then can be changed by pressing the UP or DOWN button.
REMARK:
To avoid contact bouncing, the push buttons won't react immediately,
but only after about 0.5 seconds.
