Temperature measurement 10V (Analog input)
The controller receives the measured temperature signal as a voltage signal (DC
0...10 V).
The respective temperature is calculated via the linear characteristic which is
defined by 2 fixed points (input value 1 / input value 1 and input value 2 / function
value 2).
Use of measured temperature is defined via the parameter "Temperature sensor
H1, H3" (line 5957, 5967).
Setting unavailable with H2.
Line no.

Break contact (NC)
The contact is normally closed and must be opened to activate the selected
function.
Make contact (NO)
The contact is normally open and must be closed to activate the selected function.
Line no.

These settings are available for each input Hx.
The linear characteristic is defined via 2 fixed points. The setting occurs using two
parameter pairs for input value and voltage value (F
The setting "Flow measurement Hz" converts the voltage value to a frequency
value.

If the input signal drops below the limit value of 0.15 V, the heat request is invalid
and therefore inactive.
