Wireless programmer Termojet WT-150 WT150BLK (black)

Termojet WT-150 — a wireless programmable thermostat with an E-Ink display in a black housing. The E-Ink screen is readable at any angle and in bright sunlight without backlighting, and energy consumption is so low that the built-in lithium battery with Type-C charging (5V/1A) provides long autonomous operation. The thermostat transmits commands wirelessly via the 868 MHz protocol — without any need to run wires through walls.

Technical Specifications

How It Works

The WT-150 transmits an RF signal at 868 MHz to one of two receiving devices of your choice:

• Wi-Fi receiver R06 — for controlling a single boiler or circuit. R06 connects to the boiler terminals and to Wi-Fi, enabling monitoring and control of the system through the Smart Life app.
• Wireless switching centre TJ-03-RF — for a zonal system of up to 8 independent rooms with thermoactuators. WT-150 becomes the thermostat for one zone within a unified system with boiler and pump.

Programming — 7 days with 4 temperature levels per day. Away, PRG (programmed), and Manual modes are switched directly on the thermostat. Open window detection stops heating during a sharp temperature drop and restores the mode automatically after 30 minutes.

Use Cases

• Renovation and retrofitting. Installation without wall chasing — the thermostat is mounted on the wall or placed on a table. Ideal for adding a thermostat to an already completed system.
• Wireless zone system. Multiple WT-150 units (black or white) + TJ-03-RF — a full 8-zone system without a single thermostat cable in the walls.
• Designer interiors. The flat black E-Ink thermostat, 80×80×12 mm, is a minimalist solution for dark or neutral interiors.
• Country house or additional zone. Built-in battery with Type-C charging — convenient servicing without battery replacement.

Advantages of WT-150

• E-Ink display — excellent readability without backlighting, any viewing angle.
• Type-C battery — charges like a smartphone, no special batteries required.
• Connection flexibility — R06 for simple single-circuit control or TJ-03-RF for zoning.
• Wireless installation — thermostat anywhere in the room without a cable.
• Accuracy ±0.5°C and hysteresis 0.5°C — stable maintenance of comfortable temperature.

WT-150 and Heat Pump

Wireless zoning via WT-150 and TJ-03-RF allows the heat pump to supply heat only to the zones where there is a demand — without running thermostat cables. Zone control of underfloor heating increases heat pump efficiency and reduces electricity consumption. More details at tjheatpump.com.ua.

Frequently Asked Questions

Does the WT-150 have built-in Wi-Fi?
No. Wi-Fi in the system is provided by the R06 receiver: it connects to the home network and to the Smart Life app. The WT-150 thermostat itself transmits the signal via the 868 MHz radio channel to R06 or the TJ-03-RF centre.

What is the difference between the black and white WT-150?
Solely the housing colour. Technical specifications, functions, and compatibility are identical. The white WT-150 suits light interiors; the black one suits dark or neutral interiors. The full zone control catalogue is in the Termojet section.
