MVCD|| Honeywell Damper Actuator| Control Wiring

Modulating Run Mode
If the function selection switch has been set to one of the four
modulating control settings - and if the actuator is wired
correspondingly (see Fig. 10) - then as soon as operating
power is applied, the shaft adapter will run first completely
counterclockwise and then completely clockwise (see also
section “Adaption”), after which it will run according to the
control signals applied.
Table 1 describes, for the floating mode, the shaft adapter
behavior (“stops,” rotates “CCW,” or rotates “CW”) in
dependence upon the control signals applied to terminals 3
and 4 and upon the function selection switch setting.
Table 2 describes, for the 2-position mode, the shaft adapter
behavior (“stops,” rotates “CCW,” or rotates “CW”) in
dependence upon the control signals applied to terminals 3
and 4 and upon the function selection switch setting.
Table 3 describes, for the modulating mode, the shaft adapter
behavior (“stops,” rotates “totally CCW,” rotates “totally CW,”
runs to “proportional” position, or runs to “50%” of max. stroke)
in dependence upon the control signals applied to terminals 3
and 4 and upon the function selection switch setting.

Bro, who will do this connection , electri or mech engineer ?

[@EXPLORINGPIPING]

HVAC engineer can do it, very simple .
Down load wiring diagram or go through TDS
