1.
If the flap motor drive has an additional position
feedback, the flaps can be positioned in a
selectable number of intermediate positions. If left
unconnected the flaps will go all the way to their
respective mechanical stop positions.
2.
This option is added for the case that analog
positioning of valve control motors is required. If a
single solenoid is to be used; connect the coil
between ground and either the inverted or non-
inverted output.
3.
These outputs are also available in the control unit
in order to make it possible to use only the control
unit as a compartment controller.
