Thermostat COMFORT WT-08 (radio) + smartphone app (Wi-Fi) 3ZTERWT08W

Adjusts temperature according to your life

This thermostat doesn’t just maintain the set temperature—it responds to what’s happening in your home. When you open a window, it detects a sudden 2°C drop within 15 minutes and automatically turns off heating. You don’t need to remember to do it manually. After 30 minutes, it resumes your program—or immediately if you press any button. This isn’t “smart” behavior—it’s sensible.

You can program four different modes per day: comfortable in the morning, economical during work hours, warm in the evening, and low at night. Settings operate independently for each day of the week. No need to reprogram weekly.

The display shows both the current room temperature and your target temperature—plus the time. No guessing whether the thermostat is “waiting” or already active. The backlight is bright enough to read even in a dark room in the morning.

Control from your phone—or without it

You don’t need to be near the thermostat to change it. The Smart Life app lets you set the temperature from work, on vacation, or even from your car. Just pair the device once—and everything works via Wi-Fi. No need to buy extra gateways or hubs.

But if your phone isn’t handy—no problem. The thermostat works independently. You have physical buttons, a clear display, and full local control. This isn’t a “smart” thermostat for tech nerds—it’s a thermostat for people who want choice.

Simple installation, compact size

No construction work required. The transmitter (135x88x27 mm) mounts on the wall with adhesive or screws—or simply stands on a shelf thanks to its feet. The receiver (86x86x26 mm) connects to your boiler like any standard relay: 230V, max 10A—standard contact for heaters and pumps.

Transmitter power: two AAA batteries—last a long time, since the sensor activates only during changes. The receiver runs on mains power—safe and compliant with CE and RED standards.

Accuracy of ±0.5°C means: no “flickering” between 21°C and 22°C. The NTC 10K sensor is a proven type—the same as in many professional heating systems.

IP30—not waterproof, but sufficient for indoor use. The ABS casing won’t crack in low temperatures or yellow over time.

No unnecessary features. No “energy usage analytics,” no “learning your habits.” Just what works: precise control, simple operation, and peace of mind.
