Wired programmer Termojet in flush-mount box frame HT-130 HT130BLK (black)

Termojet HT-130 — a wired Wi-Fi thermostat designed for installation in a standard wall-box frame. Unlike the HT-120, which fits into its own dedicated wall box, the HT-130 integrates into the frames of popular electrical series: ABB Basic55, Liregus Epsilon, Schneider Merten, Berker S.1 or a standard 86×86 mm frame from the manufacturer. The ideal solution for interiors where a switch and socket series has already been chosen.

Technical Specifications

How It Works

The HT-130 measures temperature using a built-in air sensor or an external floor sensor NTC10K (or both). When the temperature deviates from the set point, the relay closes: either switching on the boiler directly or sending a signal to the switching centre TJ-03-C to control an individual zone. A weekly schedule (7 days, 4 intervals per day) is set via the Smart Life app. Eco, manual, and programme modes are also available.

Where It Is Used

• Renovation with a chosen switch series. The HT-130 mounts into the same frame as the switches — no need to install a separate wall-box cover plate.
• Zone control for underfloor heating. Paired with TJ-03-C, each room is controlled independently — up to 8 zones in a single building.
• Floor + air simultaneously. The "Air & Floor" function monitors both sensors: heating stops when either the floor reaches its limit (20–80°C) or the room reaches the set temperature.
• Smart Home integration. Connected to Smart Life, schedules and scenarios are set up alongside other Termojet devices in a single app.

Advantages of the HT-130

• Installation in a standard frame — the appearance is indistinguishable from a regular switch of the same series.
• Built-in 2.4 GHz Wi-Fi — no hub required for smartphone control.
• Two sensors simultaneously — independent control of air and floor temperature.
• Mains-powered at 230 V — no batteries, no maintenance.
• Open-window detection mode — automatic heating stop during ventilation.
• Frost protection (minimum temperature in away mode) and child lock.

HT-130 and Heat Pump

When operating with a heat pump, it is important to maintain a stable low supply temperature — every degree above what is necessary reduces the system COP. The HT-130 with ±0.5°C accuracy prevents excessive room overheating and reduces frequent cycling. Learn more about efficient heat pump heating systems at tjheatpump.com.ua.

Frequently Asked Questions

What is the difference between the HT-120 and HT-130?
HT-120 is installed in its own wall box and has its own cover plate. The HT-130 mounts in the frame of an existing electrical series wall box (ABB, Schneider, Berker, etc.) — if you have already chosen a switch series, the HT-130 will fit seamlessly.

Can the HT-130 be connected without a switching centre?
Yes. The HT-130 directly controls the boiler or pump via a 3 A relay. For zone control across multiple rooms, connect it to the switching centre TJ-03-C — up to 8 independent zones.
