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.j – Dip switch configuration: X000 (Fig. 5.p)
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.k – Fig. 5.l – Dip switch configuration: X100 (Fig. 5.p)
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.q).
Wiring diagram: Fig.5.m – Dip switch configuration: X010 (Fig. 5.m)
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.k – Dip switch configuration: X011 (Fig. 5.p)
7.5 Three speed operation with CTRL-S controller (accessory on request)
The unit runs at the speed selected by activating the two-position switches “S1”, “S2” and “S3” of the CTRL-S (accessory Fig. 5.r)
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 bypass, so to mitigate the heat exchange when necessary - see 7.7.
Wiring diagram: Fig.5.o– Dip switch configuration: X110 (Fig. 5.p)
