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. A range from 8 °C ... 30 °C is permissible as setpoint temperature. The average
temperature should be 16 °C overnight.
Settings
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 Upper value = 30 °C (10 V ≙ 30 °C)
p31023[1] = 2900
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
p31025 = 722.4
