Transmitter ZEC 4 17000-0228

Ventilation control with precision – voltage transmitter ZEC 4

The ZEC 4 transmitter is a device designed for smooth speed control of fans equipped with electronic commutated motors (EC) or other devices controlled by a 0-10VDC signal. This allows for precise adjustment of the ventilation system's performance to current needs, which translates into user comfort and energy savings. This is particularly important in HVAC systems, where optimizing fan operation is crucial for the energy efficiency of the building.

ZEC 4 is not limited to fan control. Its versatility means it can be used to control various devices operating in the 0-10VDC voltage range. An additional unregulated AC output (maximum 3A) expands the possibilities of using this device, allowing simultaneous power supply to other system components. The transmitter's design ensures easy wall mounting, and the IP20 protection class guarantees safe operation in standard environmental conditions.

Functionality and application

The ZEC 4 offers intuitive operation thanks to the knob on the front panel, which allows for smooth adjustment of the output voltage in the 0-10VDC range. The "0" position of the regulator not only switches off the transmitter but also disconnects the additional AC output, which increases safety and minimizes energy consumption when the device is not in use.

• EC fan control: Precise speed control for optimal comfort and energy savings.
• Regulation of other devices: Ability to control various devices operating in the 0-10VDC voltage range.
• Additional AC output: Powering additional system components without the need for separate power supplies (maximum load 3A).
• Easy installation: Wall mounting simplifies integration with existing infrastructure.
• Safety: IP20 protection class provides protection against touch and interference.
• Wide application: Ideal for HVAC systems, building automation and anywhere where smooth 0-10VDC voltage regulation is required.

ZEC 4 is a reliable and versatile tool for installers and end-users looking for an effective solution for controlling fan speed and other electrical devices. Its simple operation and wide range of applications make it an ideal choice for both new installations and modernization of existing systems.
