7.2.3 Active measured value signal (SIGNALY)
The measured values from passive sensors can be delivered in the form of active,
continuous signals. For that, you must assign an output to the input.
Multiple use of sensors
The settings under "Measuring range" are also used for setting up the output.
You want to output the measured value from an LG-Ni1000 sensor as an active
signal of DC 0…10 V = 0…50 °C:
Example
– Lower measured value (MIN VAL): 0 °C
– Upper measured value (MAX VAL): 50 °C
The active measuring signal is only usable for analog values.
Note
Digital signals would produce an output of either DC 0 V or DC 10 V.
7.2.4 Correction (CORR)
A measured value correction can be entered for passive temperature sensors in
order to compensate for line resistance.
Compensation of line
resistance
This can be used to perform on site calibration with a reference measuring unit.
7.2.5 Special analog inputs
Certain sensors are required for special functions, such as pump ON at low outside
temperatures. Therefore, the following analog inputs provide additional, special
functions:
Special functions
– OUTS Outside temperature; see section 7.6
– ROOM Room temperature; see section 7.7
– SAT Supply air temperature; see section 7.8
The following analog inputs provide special setting values:
Special setting values
– REMx Absolute setpoint adjuster; see section 7.4
– REL Relative setpoint adjuster; see section 7.5
– FRST Frost; see section 10
