Mikoterm HT 130 – Wireless Room Thermostat (230VAC)

Wireless comfort with precise climate control

The Mikoterm HT 130 wireless thermostat offers a flexible and reliable solution for 230VAC on/off heating control. Because it operates completely wirelessly, the thermostat can be installed at the optimal measuring location, without any wiring or wall modifications.

Suitable for heat pumps, boilers and pellet systems

Thanks to its potential-free NO/NC relay contact, the HT 130 is compatible with a wide range of heating systems. Whether you are installing a heat pump, upgrading a boiler system or controlling a pellet stove, this thermostat provides accurate switching and stable performance.

Clear display and intuitive control

The large digital display shows the current temperature, setpoint and active program modes. Its intuitive layout ensures that users can easily adjust settings, even if they are not familiar with smart home equipment.

Energy-saving features

The integrated window-open detection helps save energy by turning off heating when a sudden drop in temperature is detected. Together with frost protection mode, the HT 130 ensures safe and efficient operation throughout the year.

Adjustable hysteresis for fine-tuned performance

Installers can adjust the hysteresis between –2.0°C and +2.0°C to ensure precise switching behaviour and reduce short-cycling. This makes the thermostat suitable for both low-temperature systems and traditional radiators.

Reliable wireless communication

The thermostat maintains a stable wireless connection with its receiver module. If communication is interrupted, the system switches to a safe fallback state, providing additional security for heat pump and pellet applications.
