Siemens Climatix range CB1Q3900en_02
Building Technologies 30.11.2009
This example shows how to use one POL687.70 controller together with 2
POL965, 2 POL954 and 2 POL94U extension modules. This combination is not
possible with only one AC 24 V power supply, since the total apparent power ex-
ceeds 96 VA (note that it could be done using DC 24 V).
