ROOM THERMOSTAT PLACEMENT  

ROOM THERMOSTAT HYSTERESIS NEGATIVE MENU  

The hysteresis negative 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 negative value is -0.5°C, your Room Thermostat  

will send a command to your heating unit when the room temperature  

drops 0.5°C below the set temperature. For example, when we set the  

Room Thermostat to 22.0°C, your heating unit will work when the  

room temperature drops to 21.5°C. To change the hysteresis negative  

setting  

ENGLISH  

Place 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 thermostat is placed at a  

height of 150cmfrom the floor.

CoolingMode  

As soon as you energize your Room Thermostat, it will start working.  

Your room thermostat takes the average room temperature of last 40  

seconds as basis. If the ambient temperature rises above the  

hysteresis positive temperature you set, your Room Thermostat will  

start the cooling unit and if it drops below hysteresis negative  

temperature value, will stop the cooling unit. Thus, it is ensured that  

theambient temperatureremains within acertain range.  

GENERAL SPECIFICATIONS  

FH25/FH25S is a digital room thermostat designed for underfloor  

heating and cooling system. The user can get more comfortable and  

economic heating/cooling by adjusting the room thermostat with the  

required temperature.

Temperature sensors used in Room Thermostats are very sensitive.  

Based on the temperature on the thermometers in your living space  

youneed to calibrateyourRoom Thermostat. For this:

*Incaseof floor sensor connected, the following 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 the floor sensor temperature:

Summary of Contents

• Page 1: Room thermostat placement is important for accurate temperature readings. The hysteresis negative factory setting is -0.5°C, adjustable between -0.1°C and -2.0°C. The room thermostat will activate heating when the temperature drops 0.5°C below the set temperature. It is recommended to place the thermostat at a height of 150 cm from the floor and away from air circulation areas. The device takes the average room temperature of the last 40 seconds as a basis for operation. The factory temperature setting for the floor sensor is 28°C, adjustable between 23°C and 34°C. The room thermostat has heating and cooling modes that can be switched easily. Calibration of the room thermostat is necessary based on the temperature readings in your living space. You can reset the room thermostat to its factory default settings if needed. The hysteresis positive factory setting is 0.5°C, adjustable between 0.1°C and 2.0°C.
