## Long description

TFA 30.1066.01 is an electronic environment thermometer for indoor and outdoor temperature monitoring. It displays temperature in degrees Celsius and is powered by a single 1.5 V AAA battery. The unit has a compact housing (15 × 54 × 40 mm) and offers both a built-in sensor and an external sensor probe connected by a cable, enabling flexible placement for measuring room or outdoor conditions.
Advantages
The thermometer provides an easy switch between indoor and outdoor readings with a single button and can be set to alternate the displayed value every 5 seconds. Maximum and minimum temperature values are automatically stored and can be recalled. Two small magnets on the rear allow attachment to metal surfaces and a fold-out stand provides tabletop placement. The external sensor probe is waterproof, expanding use cases to locations where a cable-mounted probe is required.
Suitable for
Home rooms and living spaces
Office desks and meeting rooms
Greenhouses and balconies (outdoor measurements)
Cars, refrigerators or aquariums using the waterproof probe

How to use
Install one 1.5 V AAA battery in the battery compartment following polarity markings. Place the main unit indoors and route the sensor cable to the desired outdoor position if measuring outdoor temperature; the probe can be positioned outside a window or in another remote location. Use the push button to switch between indoor and outdoor readings or to enable the alternating display mode. Recall stored maximum and minimum values using the designated recall function.
Usage recommendations
For accurate outdoor readings, position the waterproof probe away from direct sunlight and heat sources and ensure the cable run does not expose the main unit to moisture. Use the magnets for temporary metal mounting or the fold-out stand for stable indoor placement. When using the probe in cold, wet, or humid environments (for example, refrigerator, aquarium or car), check cable routing and probe sealing regularly. Replace the AAA battery when display dimming or irregular updates occur.
