8.7 Application-specific functions
Example
In an open plan office, temperature sensors (Lg-Ni1000) are installed in three different
places. The inverter receives the measured values and temperature setpoint via its analog
inputs. Temperature setpoints between 8 °C ... 30 °C are permissible. Overnight the average
temperature should be 16 °C.

p2200.0 = 1
p2251 = 0
p2900.0 = 16
p31020 = 1
p31021 = 0
p31022 = 7
p31023.0 = 755.0
p0756.0 = 0
p0757.0 = 0 / p0758.0 = 8
p0759.0 = 10 / p0760.0 = 30
p31023.1 = 2900.0
p31026.0 = 755.2
p0756.2 = 6
p0757.2 = 0 / p0758.2 = 0
p0759.2 = 100 / p0760.2 =
100
p31026.1 = 755.3
p0756.3 = 6
p0757.3 = 0 / p0758.3 = 0
p0759.3 = 100 / p0760.3 =
100
p31026.2 = 755.1
p0756.1 = 2
p0757.1 = 0 / p0758.1 = 0
p0759.1 = 20 / p0760.1 = 100 Set upper value of the scaling characteristic (20 mA ≙ 100%)
p31025 = 722.4
You will find more information about this multi-zone control in the parameter list and in
function diagram 7032 of the List Manual.

Technology controller enable
Set technology controller as main setpoint
Temperature setpoint overnight as a fixed percentage value
Activate multi-zone control
Select multi-zone control with one setpoint and three actual
values
Three actual values, one setpoint. The average value of the
three actual values is used for the control.
Temperature setpoint via analog input 0
Select analog input type (voltage input 0 ... 10 V)
Set the lower value to 8 °C (0 V ≙ 8 °C)
Set the upper value to 30 °C (10 V ≙ 30 °C)
Supply p31023.1 with the value written in P2900 to reduce
the temperature overnight
Temperature actual value 1 via analog input 2 as a
percentage value
Select analog input type (temperature sensor LG-Ni1000)
Set lower value of the scaling characteristic
Set upper value of the scaling characteristic
Temperature actual value 2 via analog input 3 as a
percentage value
Select analog input type (temperature sensor LG-Ni1000)
Set lower value of the scaling characteristic
Set upper value of the scaling characteristic
Temperature actual value 3 via temperature sensor with
current output (0 mA ... 20 mA) via analog input 1
Select analog input type (current input 0 ... 20 mA)
Set lower value of the scaling characteristic (0 mA ≙ 0 °C)
Changeover from day to night via digital input 4
