UNDERFLOOR HEATING THERMOSTAT  

*Incaseof floor sensor connected, thefollowing settingsapply.  

The factory temperature setting for floor sensor is 28°C. This value can  

be adjusted between 23°C and 34°C. The floor sensor operating  

sensitivity is 1°C. For example, when you set the floor sensor  

temperature to 28°C, your Room Thermostat will stop the heating unit  

from working when the floor temperature rises to 29°C. When the floor  

temperature drops to 27°C, it starts the heating unit of the Room  

Thermostat. To change thefloor sensor temperature:

ROOM THERMOSTATTEMPERATURE CALIBRATION  

Temperature sensors used in Room Thermostats are very sensitive.  

Based on the temperature on the thermometers in your living space you  

need to calibrateyourRoom Thermostat. For this:

You can reset the Room Thermostat to its factory default settings. This  

action resets the calibration setting and hysteresis settings to the  

factory setting. To factory resetyourRoom Thermostat:  

The hysteresis positive factory setting of your Room Thermostat is  

0.5°C. This value can be adjusted between “0.1°C” and “2.0°C”. While the  

hysteresis positive value is 0.5°C, your Room Thermostat will send a  

command to your heating unit when the room temperature rises 0.5°C  

above the set temperature. For example, when we set the Room  

Thermostat to 22.0°C, your heating unit will stop when the room

ROOM THERMOSTAT WORKING PRINCIPLE  

As soon as youenergizeyourRoom Thermostat, it will start working. It is  

based on the average temperature of the environment where the Room  

Thermostat is located in the last 40 seconds. If the ambient  

temperature rises above the hysteresis positive temperature you set,  

your Room Thermostat turns off the heating unit, and if it drops below  

hysteresis negative temperature value, it turns on the heating unit.  

Thus, it is ensured that the ambient temperature remains within a  

certain range.

ROOM THERMOSTAT PLACEMENTPlace your Room Thermostat in a  

room you use frequently in your living space. For example; like the hall or  

living room of your home. Avoid installing the Room Thermostat in  

places where there is a lot of air circulation, such as at the doorway or by  

the window. Also, do not place it close to heating units (heater core,  

fireplace, etc.) and in direct sunlight. We recommend that the room  

thermostatis placed ataheight of 150cmfrom thefloor.
