Wired programmer Termojet in flush-mount box frame HT-130 HT130WHT (white)

Termojet HT-130 — a wired Wi-Fi thermostat for hydronic underfloor heating, designed to be mounted in a standard wall-box frame. Unlike the HT-120, which occupies the entire wall box on its own, the HT-130 integrates into the frames of popular series: ABB Basic55, Schneider Merten, Berker S.1, Liregus Epsilon or a standard 86×86 mm frame — fitting seamlessly into the existing electrical design. Colour: white.

Technical Specifications

How It Works

The HT-130 works in the same way as the HT-120, but in a different form factor. Built-in 2.4 GHz Wi-Fi provides direct connection to the Smart Life app without additional gateways. Sensor mode — selectable: air (built-in), floor (external NTC10K) or both simultaneously. The floor overheat limit is adjustable within 20–80°C.

In an 8-zone system, the HT-130 connects by wire to the switching centre TJ-03-C. The switching centre opens the actuator of the required zone and switches on the boiler and pump only when there is an actual heat demand.

Usage Scenarios

• Renovation with designer electrics. If ABB, Schneider or Berker frames are already installed in the apartment or house — the HT-130 fits into the same series without rewiring.
• Thermostat replacement without changing the frame. Suitable for situations where the wall frame remains — only the mechanism is replaced with a smart Wi-Fi thermostat.
• Room zoning. Paired with TJ-03-C and thermoactuators — up to 8 independent underfloor heating zones with individual weekly schedules.
• Voice and remote control. Smart Life, Google Home, Amazon Alexa — control from anywhere without a hub.

Advantages of the HT-130

• Installation in a ready-made frame — fits the design without additional covers or modifications.
• The same features as the HT-120: built-in Wi-Fi, Smart Life, Alexa, Google Home, two sensor modes, floor overheat protection.
• Open-window detection and frost protection — standard safety features.
• Also available in black HT-130 BLK for dark electrical accessory series.

HT-130 and Heat Pump

Zone control of underfloor heating via the HT-130 and TJ-03-C allows the heat pump to deliver heat precisely where there is demand. This reduces unnecessary cycles and improves the efficiency of the low-temperature system. Learn more about Termojet heat pumps at tjheatpump.com.ua.

Frequently Asked Questions

What is the difference between the HT-120 and HT-130?
Functionally — identical: the same Wi-Fi, Smart Life, sensors, floor protection. The difference is in the form factor: the HT-120 mounts independently in any wall box, the HT-130 integrates into the frame of the corresponding series (ABB, Schneider, Berker, Liregus or 86×86 mm). Choose depending on the electrical accessories already in the room.

Is an NTC10K sensor required for underfloor heating?
Recommended. The NTC10K sensor is laid in a conduit under the floor and protects the surface from overheating — particularly important for parquet and laminate. The full catalogue is in the zone control section.
