If the input signal drops below the limit value of 0.15 V, the heating demand is invalid
and therefore has no effect.
• Example of pressure measurement 10V
U1 Voltage value 1
F1 Function value 1
U2 Voltage value 2
F2 Function value 2
• Example of relative room humidity 10V

0.15V
Relative Feuchte [%]
U2=5V
U1 Voltage value 1

U2 Voltage value 2
F2 Function value 2
If the measured value is below 0.15V it is regarded as invalid and an error message is
generated.
