In both heating and cooling modes, the unit can integrate a sensor to turn off the fan if the water temperature is too low (for heating) or too high (for cooling). 5. Top Tips for a Smooth Installation Locate the small DIP switches on the back

Following the official steps ensures the unit is secured properly and functions as intended.

The is a high-performance, microprocessor-controlled electronic thermostat engineered specifically for 2-pipe and 4-pipe fan coil units (FCU) with AC fan motors. This commercial-grade zone controller regulates ambient temperatures within a standard 10°C to 30°C (50°F to 86°F) range, featuring advanced energy-saving dip-switch configurations and automatic fan speed modulation.

Once the wiring is secure and the thermostat is snapped onto the subbase, the job isn't done. The manual outlines specific "Configuration Menu" steps.

Carefully snap the base away from the main unit at the hinge. 3. Setup and Configuration

Protects against freezing in unoccupied spaces. This function keeps the room temperature from dropping below . If the temperature dips to this level, the control will automatically activate the valve and the fan on high speed. Critically, this function remains active even if the control is in the OFF position.

To ensure precise room temperature readings and reliable automatic fan control, correct placement is vital. Ideal Placement Criteria

The control can use an internal or external sensor, set via the on the circuit board.

Avoid mounting on exterior walls, near air discharge vents, or in direct sunlight. These factors cause "ghost" temperature readings that lead to inefficient cycling. 3. Setup and Configuration
