Note
If you deactivate the multi-zone control, the inverter resets the interconnection of its analog
inputs to the default setting.
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.

Parameters to set the multi-zone control:
Description
Technology controller enable
Set technology controller as main setpoint
Multi-zone control interconnection
(factory setting = 0)
A subsequent parameterization is performed by activating or deactivating the multi-
zone control.
Subsequent connection for p31020 = 1 (activate multi-
zone control)
p31023[0] = 0755[0] (AI0)
p31023[2] = 0755[1] (AI1)
p31026[0] = 0755[2] (AI2)
p31026[1] = 0755[3] (AI3)
p2253[0] = 31024 (setpoint output, technology controller)
p2264[0] = 31027 (actual value output, technology con-
troller)
Configuration of multi-zone control
0 = Setpoint 1 / several actual values (factory setting)
•
1 = Two zones / maximum value setting
•
2 = Two zones / minimum value setting
•
Processing of actual values for multi-zone control (only for p31021 = 0)
Possible values: 0 ... 11 (factory setting = 0)
Setpoints for multi-zone control
Selection of the source for setpoints in multi-zone control (factory setting = 0)
Multi-zone control setpoint output for the technology controller
Switching from day to night mode for multi-zone control
Selection of the source for switching between day and night operation by the multi-
zone control (default setting = 0)
Actual values for multi-zone control
Selection of the source for actual values of the multi-zone control (factory setting = 0)
Multi-zone control actual value output for the technology controller
Subsequent connection
for p31020 = 0 (deactivate
multi-zone control)
p31023[0] = 0
p31023[2] = 0
p31026[0] = 0
p31026[1] = 0
p2253[0] = 0
p2264[0] = 0
