How Does an Actuator Operate?
According to Honeywell Manuals, Honeywell Fan Coil Actuators operate in 2 different modes; Automatic, Manual.
What Does Each Stage Do?
Automatic Operation
On a call for heat or cool by the fan coil thermostat, the valve motor operates, opening the valve. When the call ends, the valve closes by integral spring return.
Manual Operation
The 2-way normally closed and 3-way motorized valve actuators can be opened manually by lifting the manual opening lever over the stop and pushing slowly and firmly to the MANUAL. OPEN position. The stop permits the valve to be locked in the open position. The valve returns to an automatic position when it is energized.
Normally Closed Models
As per manufacturer guidelines, the actuator is energized when the manual opener set to AUTO. Then A port is opened as shown in Fig. 11A and 12A. When the actuator is de-energized, a spring-return mechanism drives the valve to the port A closed position as shown in Fig. 11B and 12B. The valve can also be opened with no electrical power by moving the manual opening lever over the stop and pushing slowly and firmly to the MANUAL to OPEN position. The stop permits the valve to be locked in an open position. The valve returns to the automatic position.

Why Do I Hear Strange Noise Throughout the Day From Your Fan Coil System?
Note From Honeywell: fan coil valves are designed and tested for silent operation in properly designed and installed systems; however, water noises can occur as a result of excessive water velocity or piping noises can occur in high temperature (higher than 212°F (100°C)) systems with insufficient water pressure. Valves are designed for normal cycling operations. Product life will be shortened if energized continuously.
