Connecting power, the motor of the actuator drives other parts and overcomes the resistance from the spring and push the valve stem downwards. When power is off, return spring overcomes pressure from a medium, and push stem to close position.
Actuator drives stem moving downward and valve core overcomes resistance from stainless spring and moves away from the valve seat, open normally closed port.
When assembling the fan coil driver with the S6057 series fan coil valve, the following requirements should be followed:
The water flow direction must be the same as the arrow direction on the valve body so that the valve core can block the water flow.
Valves and drivers must be installed within 90° of the vertical direction, without dripping water, easy for electrical installation
The valve must be connected to the water pipe with appropriate equipment.
Do not use the driver as a lever to move the valve body.
The driver should not use heat insulation material, and there should be at least 20mm space above it for assembly and disassembly.

Manual operation should not be over-force avoiding the damage of the actuator.
The water quality should meet VDI-2035 or similar requirements for HVAC applications. Other media for valve must be approved by Electronics.
The electric supply to the actuator should be shut off when repairing to avoid possible damage to the equipment, personal injury or shock.
Do not touch or disconnect wires when power is on.
