Make sure that specific warnings and cautions in Chapter 2 "Precautions" are carefully read, understood and applied!
7.1 Single speed operation
The unit runs at the speed set by turning the integral trimmer "V1" in the terminal box.
This is the default factory setting.
Wiring diagram: Fig.5.k – Dip switch configuration: 0000 (Fig. 5.q)
7.2 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.
Wiring diagram: Fig.5.l – Dip switch configuration: 1000 (Fig. 5.q)
7.3 Variable speed operation with CTRL-M remote manual controller (accessory on request)
The unit runs at the speed set by turning the knob of the CTRL-M remote manual control panel (accessory, Fig.5.r).
Wiring diagram: Fig.5.m – Dip switch configuration: 0100 (Fig. 5.q)
7.4 Variable speed operation through external domotic (BMS) system or ballast potentiometer
The unit runs at the speed set by turning the knob of an external 1-10V ballast potentiometer or set by an external 1-10V signal from a domotic (BMS) system.
Wiring diagram: Fig.5.n – Dip switch configuration: 0110 (Fig. 5.q)
7.5 Three speed operation with SEL-3V speed selector (accessory on request)
The unit runs at the speed selected by turning the knob of the SEL-3V speed selector (accessory, Fig.5.s).
Speed 1 is set by turning the integral trimmer "V1" in the terminal box.
Speed 2 is set by turning the integral trimmer "V2" in the terminal box.
Speed 3 is the maximum speed achievable by the unit.
Wiring diagram: Fig.5o – Dip switch configuration: 1000 (Fig. 5.q)

Speed 1 is set by turning the integral trimmer "V1" in the terminal box.
Speed 2 is set by turning the integral trimmer "V2" in the terminal box.
Speed 3 is the maximum speed achievable by the unit.
S3 switch allows to activate the "free cooling " operation (bypass) by reducing the intake airflow, so to mitigate the heat exchange when necessary.
Wiring diagram: Fig.5.p – Dip switch configuration: 1100 (Fig. 5.q)
7.7 Anti-frost functionality
The unit is equipped with a thermostat which, when necessary, reduces the speed of the intake fan to prevent the freezing of the heat exchanger, which could
get damaged irreparably.
