Thermostatic head COMFORT HT-10R (wireless) 3ZTEZHT10R

Automatic temperature regulation without manual adjustment

The COMFORT HT-10R thermostat head eliminates the need for manual radiator temperature setting – it automatically controls water flow based on the actual room temperature. This prevents situations where it becomes too hot because someone forgot to lower the setting, or too cold due to an accidental change. The device does not control the boiler – only the valve on the radiator to which it is mounted.

Precise control and intuitive operation

The built-in LCD display shows the current and set temperature, as well as the time and day of the week – clearly readable even in bright sunlight. Five buttons on the housing allow easy switching between modes: manual, programmable (PRG), off, and open-window mode. The PID regulator ensures smooth and precise valve opening/closing – no vibration or abrupt operation, which extends the mechanism's lifespan.

You can program an individual cycle for each day of the week – for example, nighttime temperature reduction on Mondays and Wednesdays, and comfortable temperatures on weekends. Settings are stored in EEPROM memory – they will not be lost after battery replacement.

Open-window mode and remote control (optional)

If the room temperature suddenly drops by 2°C within 15 minutes – for example, due to an opened window – the thermostat head automatically switches off heating. After 30 minutes, it returns to the normal program, or immediately upon pressing any button. This is a function that truly works – no need to remember to turn off heating during ventilation.

Wi-Fi control is possible, but is not included in the set. For this, an additional E-Hub (sold separately) is required. After connecting and pairing with the Smart Life app, you can change programs from your phone, check the battery status, or activate vacation mode from anywhere.

Installation and power supply

The M30x1.5 connection thread fits most thermostatic valves – no special adapters are required. The set already includes three adapters: DANFOSS RA, RAV, and RAVL – simply select the one suitable for your valve.

Powered by two AA alkaline batteries. Power consumption is low: up to 100 μA in standby mode without backlight, and during valve operation it does not exceed 300 mA. The battery level indicator on the screen warns of low battery.

Compliance and safety

The device complies with CE, ROHS, and RED standards – it has confirmed radio compatibility at 868 MHz. The IP20 protection rating indicates it is intended for use in dry indoor environments – not suitable for installation in bathrooms or kitchens with high humidity.
