Wireless programmer Termojet WT-150 WT150WHT (white)

Termojet WT-150 — a wireless surface-mount thermostat with an E-Ink display and a rechargeable battery charged via Type-C. The E-Ink screen is perfectly readable from any angle and in direct light, consuming power only when updating the image. Body dimensions 80×80×12 mm — the thermostat barely protrudes from the wall. Measurement accuracy ±0,5°C, radio signal range 868 MHz.

Technical Specifications

Operating Principle

The WT-150 transmits a signal over the 868 MHz radio channel to one of two paired devices:

• Single boiler (one zone): WT-150 → Wi-Fi receiver R06 → boiler. The R06 connects to Smart Life for remote access.
• Zone system (multiple rooms): WT-150 → wireless switching centre TJ-03-RF → boiler + pump + up to 16 thermoactuators. Up to 8 WT-150 (or WT-102) thermostats can be connected to the TJ-03-RF for 8 independent zones.

The WT-150 also displays the relative humidity of the room and supports "Away" mode (absence mode) with automatic return to the comfort temperature.

Applications

• Minimalist interior. The flat 12 mm body and matte E-Ink display without backlighting — the thermostat looks like a design object rather than a technical device.
• Renovation without wall chasing. Mounts on the wall without cables; charged via Type-C just like a phone.
• Zone control together with TJ-03-RF. In an underfloor heating system, the WT-150 controls one zone within an 8-zone centre — each room with its own schedule.
• Room with occasional use. "Away" mode automatically lowers the temperature to the minimum in the absence of occupants and restores the comfort temperature on schedule.

WT-150 Advantages

• E-Ink display — clear readability in any lighting, without backlighting, minimal energy consumption.
• Type-C battery — charging with a standard cable, no need to buy batteries.
• Body 80×80×12 mm — the thinnest thermostat in the Termojet range.
• Two connection options: R06 (one zone) or TJ-03-RF (up to 8 zones).
• Humidity display — an additional comfort parameter right on the display.
• Open window detection (OWD), freeze protection, child lock.

WT-150 and the Heat Pump

The slim profile and E-Ink display of the WT-150 look particularly natural in homes with modern design where a heat pump and underfloor heating system are installed. Precise temperature maintenance of ±0,5°C in each zone allows the pump to operate at a constant low load — without sudden fluctuations. Learn more about Termojet heat pumps at tjheatpump.com.ua.

Frequently Asked Questions

What is the difference between WT-150 and WT-102?
WT-102 — LCD display, AAA batteries, compact body. WT-150 — E-Ink display, Type-C battery, flat body 80×80×12 mm, humidity display. Both connect to R06 or TJ-03-RF and are functionally equivalent.

Is the EGW-100 hub required for the WT-150?
No. The WT-150 works with the R06 receiver (one zone) or the TJ-03-RF centre (up to 8 zones). The EGW-100 hub is intended for TRH-10 thermostatic heads, not for WT-series thermostats.
