- Page 2 Typically in chilled ceiling, VAV, unit ventilators, fan coil unit and other terminal unit ap- plications ● Max.10 units of SSB161.05U can operate in parallel, provided the controller output suffices. Technical design When the actuator is driven by DC 0…10 V positioning signal, it produces a stroke, which is transmitted to the valve stem.
