Operation Manual

Setting up using the AC adaptor:

1) Power up all the sensors as described in setting up using

batteries above

2) Using the AC adaptor (included), plug it into the mains

outlet and power up the base station by inserting the

adaptor jack into the 6.0V DC socket located on the side

of the base station

Every time the thermo-hygro sensor is powered up (for exam-

ple after a change of batteries), a random security code is

transmitted and this code must be synchronized with the base

station to receive weather data.

When the base station is powered up, a short beep will sound

and all LCD segments will light up for about 5 seconds before

it enters into a 15 minute learning mode to learn the sensors

security code. After the learning mode (or by pressing the

MIN/MAX key at anytime), the base station will start the

DCF77 radio controlled time reception.

Note for DCF77 Radio Controlled Time:

The time and date display is based on the signal provided by

a highly accurate Caesium atomic clock operated by the

Physikalisch Technische Bundesamt in Braunschweig (Ger-

many). This radio-controlled clock does not only provide for

the weather station’s time and date display but also functions

as the time source for all of this weather station’s memory and

history values using time and date information.

LED backlight:

When using the power adaptor or under battery operation, the

LED backlight will switch on for 15 seconds when any key is

pressed.

6. Operation using cable connection or wireless

433MHz

Cable Connection:

Using this method of operation will provide interference free

transfer of the weather data from the sensors to the base

station. The data sending interval from the sensors to the

base station will also be more frequent compared to using
