a. Dryer. The temperature of the heating agent is adjusted with “+” and “-“ switches: 4 levels from 30 °C to 60 °C
b. Space heater. The temperature of the room is adjusted with “+” and “-“ switches: 8 levels from 17 °C to 24 °C.
Functionality is available in the configuration with the external temperature sensor.
c. Controller switches the heating element off when the window is opened. Functionality is available in the
configuration with the external open door/ window sensor.
d. Weekly and daily programmer with possibility of setting 3 time zones per day –only in configuration with the
mobile application.
e. The dryer mode function with the possibility of setting the operating time:
- timer „START” –after max 4 hours the electric heating element switches off,
- timer „TURBO” – after max 4 hours the electric heating element returns to the previous setting,
- timer „DELAY” –switching the device on with the delay max. 8 hours –operating time max. 4 hours.
f. „HOLIDAY” mode –the possibility to quick decrease set temperature to the lowest level: 17˚C for the room and
30˚C for the radiator – functionality is available in configuration with the mobile application.
g. „Parental control” –the possibility of lock the keyboard from the mobile application.
h. Energy consumption meter –functionality is available in configuration with the mobile application.
i. Intelligent visualisation of operating modes: heating, setting, timer, failure –colourful LED technology.
j. The controller may be rotated by 330°.
k. Intelligent operation control –microprocessor-based control.
l. Protection against agent freezing –Antifreeze function.
m. Three-level thermal protection.
- the regulation controller prevents the temperature from exceeding 60 °C.
- in case of an uncontrolled temperature increase, the thermal fuse cuts out the power if any damage of the
regulator or temperature sensor occurs.
- protection of the heating element against "operating in a dry radiator", meaning operating outside the radiator
or operating on the radiator without any heating agent inside. In case of a sudden temperature rise, the
electronic system applied in the controller switches off the heating element at 87˚C, above which the single-
usage thermal fuse actuates.
n. The application of advanced electronics at the “operating” mode and the electronics of Ultra-Low-Power
Technology at the “stand-by” mode provides the low power consumption.
