6 COMMISSIONING AND OPERATION
6.1. Two-speed operation with remote switch (default setting)
The unit comes pre-wired to run at the speed set by turning the integral trimmer "V1" on the internal electronic circuit (Fig. 5.j)
and can be boosted to the second speed, which is set by turning the integral trimmer "V2". The second speed is activated, when
needed, by means of a remote switch (not supplied).
Factory setting:
"V1" (first speed) 30m /h @0Pa
3
"V2" (second speed) 380m
Dip switch configuration: 1000 for QCMEV 125 HY
Dip switch configuration: 1001 for QCMEV 125

6.2 Single speed operation

The unit runs at the speed set by turning the integral trimmer "V1" on the internal electronic circuit.
