Wiring diagram: Fig. 5A - Dip switch configuration: 0001 for QCMEV 80/125 (Fig. 5F).
Two speed operation
The unit runs continuously at the speed set by turning the integral trimmer "V1" in the terminal box and can be
boosted at high speed, which is set by turning the integral trimmer "V2" in the terminal box. Boost is activated,
when needed, by means of a remote two-position switch (not supplied) or by means of remote sensors (SEN-
HY, SEN-CO2 or SEN-PIR), which are accessories on request.
