TERMOFOL TF-WIFI Mark II Benutzerhandbuch Seite 27

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 nature, and its purpose is, similarly to the measure-
ment 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%.
Temperature of installation surface
INFORMATION:
It is forbidden to connect a heating device which nominal output
power exceeds 3000W to the thermoregulator. 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 3000W requires the use of a contactor.
Correct configuration and operation of the thermoregulator is an
obligatory condition to be able to make use of the statutory warran-
ty and warranty rights granted by the manufacturer of the thermo-
regulator.
