How it Works:

1. Call for Cooling: When the room thermostat detects the temperature is above the set point, it sends a 24-volt signal to the water valve.

2. Valve Opens: The valve’s internal solenoid receives this signal and opens, allowing chilled water to flow into the fan coil unit’s heat exchanger.

3. Heat Exchange: The unit’s fan blows room air across the cold coil, cooling the air. The water absorbs the heat and returns to the chiller to be re-cooled.

4. Satisfied Thermostat: Once the room reaches the desired temperature, the thermostat cuts the 24-volt signal.

5. Valve Closes: The water valve closes, stopping the flow of chilled water to that zone. The fan may continue to run for a short time to utilize residual coolness.

Key Features and Specifications to Look For:

• Voltage: Must match the control voltage of your system (almost always 24V AC).

• Type: Normally Closed (NC) is standard. This means the valve is closed when no power is applied, a safety feature to prevent unwanted water flow.

• Pipe Size & Connection: Must match the existing pipes in your system (e.g., 1/2″ Female Thread).

• Function: On/Off (2-way) vs. Modulating. “Universal” valves are typically the simpler On/Off type.

• Media: Must be suitable for water/glycol mixtures.
