Connector S1 (under the cover, on the printed circuit board) can be repositioned to
change the flow characteristic of valves with a 5.5 mm stroke from "equal percentage" to
"linear"; in all cases the flow characteristic relates to the through-port of the valve.
• Connecting S1 to pins A and C produces an equal percentage flow characteristic
(factory setting), primarily for heating applications
• Connecting S1 to pins B and C produces a linear flow characteristic,
primarily for cooling applications
• For automatic operation, S1 must be connected either to pins A and C, or B and C,
depending on the required flow characteristic.
