CERES FH25S Underfloor Heating Thermostat

It’s now easier and more efficient to set the temperature as you wish. CERES FH25S underfloor heating thermostat helps you to precisely control the temperature of your home. You can save energy and optimize your comfort. Thanks to its easy installation, start using it straight away and adjust the temperature of your home to your liking. Temperature control is just a touch away!

You can achieve maximum savings and comfort by controlling underfloor heating systems, which are preferred to provide a comfortable indoor climate, increase energy efficiency and achieve an aesthetic appearance, with the Underfloor Heating Thermostat. You can control your underfloor heating thermostat with the optional floor sensor connection or with room temperature measurement.

INCREASE HOME COMFORT AND SAVE ENERGY WITH THE OPTIONAL FLOOR SENSOR.

Optional Floor Sensor

The optional Floor Sensor continuously measures the floor temperature and transmits this information to the thermostat. Thus, temperature fluctuations are better balanced and you can maintain the desired temperature in every corner of your home. Especially in rooms with underfloor heating, this sensor makes it much easier to achieve ideal comfort.

*GENERAL Life floor sensor must be connected to the underfloor heating thermostat.

Overheat Protection

If the optional floor sensor is connected, the overheat protection will be active at 28°C. If the GENERAL Life floor sensor measures 1°C above the set temperature, your Room Thermostat will turn off the heating unit. If it measures 1°C below the set temperature, your Room Thermostat turns on the heating unit.

Thus, it provides savings and comfort by keeping the ambient temperature within a certain range.

*GENERAL Life floor sensor must be connected to the underfloor heating thermostat.

Floor Sensor Temperature Adjustment

If an optional floor sensor is connected, the floor sensor temperature setting must be adjusted. The factory temperature setting of the floor sensor is 28.0°C. This value can be adjusted between 23.0°C and 34.0°C. Floor sensor operating accuracy is 1.0°C.

*When the floor sensor temperature setting is 28.0oC, your heating unit stops when the floor temperature increases to 29.0oC, and your heating unit starts when it decreases to 27.0oC.

Hysteresis Setting

The room thermostat hysteresis setting determines how often or with how many degree differences the room thermostat will attempt to reach the desired temperature value. The hysteresis setting can be described as the operating sensitivity setting. The factory operating sensitivity of Room Thermostats is 0.5oC. This setting determines the difference between the set temperature on the room thermostat and the current temperature in the room. Operating sensitivity can be changed with hysteresis positive and hysteresis negative settings.

*When the operating sensitivity is 0.5oC, if you set the desired temperature to 23.0oC, your heating unit stops when the room temperature rises to 23.5oC, and your heating unit starts when it drops to 22.5oC.
