Setup
1. Battery Installation
The main unit and the outdoor sensor each require 2 x AAA LR3 batteries (not included).
- Open the battery compartment cover on the back of the main unit.
- Insert 2 new AAA LR3 batteries, observing the correct polarity (+ and -).
- Close the battery compartment cover.
- Repeat steps 1-3 for the wireless outdoor sensor.
Important: Always replace all batteries at the same time. Do not mix old and new batteries or different types of batteries.
2. Initial Synchronization
After installing batteries, the main unit will automatically search for the outdoor sensor and the radio-controlled time signal.
- Place the outdoor sensor within 1 meter of the main unit during initial setup.
- The main unit will display outdoor temperature once synchronized. This may take a few minutes.
- The radio-controlled time signal (DCF77) will be automatically received. This process can take several hours, especially in areas with weak signals.
3. Sensor Placement
For accurate outdoor temperature readings, place the wireless sensor in a shaded area, protected from direct sunlight and precipitation. Ensure it is within the 60-meter transmission range of the main unit, free from major obstructions.
Operating Instructions
1. Time and Date Settings
The station automatically sets the time and date via radio control. Manual adjustment is possible if the signal is not received.
