Hysteresis of the external floor sensor – additional information:
the limit of a temperature value measured by the external floor sensor is of 28 °C for the factory setting
of the advanced options and the factory value of the external floor sensor hysteresis is of 2 °C. When the
temperature rises to 28 °C, the thermostat stops supplying the controlled heating device and reminds
you of the high temperature alarm. If the temperature measured by the external floor sensor decreases
to 26 °C, the thermostat will start supplying the controlled heating device again (only if the air temperatu
-
re in the room is lower than the set temperature). The thermostat will not supply power to the controlled
heating device until the error has been corrected!
INSTALLATION OF THE EXTERNAL SENSOR
Place the protective conduit in the groove in the floor with the sensor inside. The end of the protective
conductor must be sealed. The sensor wire can be extended up to 50 meters with other wires, if neces
-
sary. If a multi-core cable is used for the extension, it must not be used for power supply (e.g., for the
heating cable) in order to avoid interference of the voltage signal with the heating signal of the thermo
-
stat. The resistance of the NTC sensor must be measured.
The resistance of the NTC sensor is measured with a universal meter set to measure resistance in the
range from 20 kΩ. The measurement of the floor sensor resistance is of control and informational natu
-
re, and its purpose is, similarly to the measurement of the heating system resistance, to exclude damage
of the connection wire (e.g., its tearing when pulling it into the conduit) or the NTC sensor itself. Approxi
-
mate resistance values, depending on the temperature of the installation base, are given in the following
table. Tolerance of the measured value is +/– 10%.
INFORMATION:
It is forbidden to connect a heating device which nomi

nal output power exceeds 3600W to the thermoregu

lator. Exceeding this value may cause damage to the
thermoregulator or even fire in the over-loaded system.
Connection of a heating device with power greater than
3600W requires the use of a contactor. Correct configu
