Alpha-5 Actuator for Underfloor Heating 24V (AC/DC) - NO Type VA80

Продукт болееview

The Alpha 5 is a thermoelectric actuator designed to open and close small valves and flaps on heating circuit distributors for surface heating and cooling systems. It enables energy-efficient individual room control in home automation systems.

Thanks to its innovative and patented valve adapter concept, the Alpha 5 actuator can be perfectly adapted to most heating circuit distributors and valve lower parts. It is intended for the automatic control of return valves on the heating circuit distributor via a room thermostat.

Основные характеристики:

• Operating power: Only 1 W, ensuring high efficiency.
• Supplied with a 1-meter connection cable (non-removable).
• Normally Open (NO) operation: Opens without power.
• 360° mounting position for flexible installation.
• First-Open function for initial system setup.
• Function display for operational status.
• TÜV certified for quality and safety.
• Ход поршня: 4 мм.

Настройка и установка

The Alpha-5 actuator is designed for straightforward installation on heating circuit distributors. The following steps outline the general installation process. Always ensure power is disconnected before beginning installation.

1. Step 1: Prepare the Valve. Ensure the valve on the heating circuit distributor is ready for actuator attachment. If an existing cap or manual control knob is present, remove it.
2. Step 2: Attach the Adapter. The Alpha-5 actuator comes with a suitable valve adapter. Screw this adapter onto the valve thread of the heating circuit distributor. Ensure it is securely fastened but do not overtighten.
3. Step 3: Position the Actuator. Align the Alpha-5 actuator with the adapter. The actuator is designed for a 360° mounting position, offering flexibility.
4. Step 4: Secure the Actuator. Gently push the actuator onto the adapter until it clicks into place. This "click" indicates a secure connection.
5. Шаг 5: Электрическое подключение. Connect the 1-meter cable of the actuator to the appropriate 24V (AC/DC) control circuit, typically managed by a room thermostat. Ensure wiring is done according to local electrical codes and safety standards.

After installation, restore power to the system. The actuator's function display will indicate its operational status. The First-Open function facilitates initial system startup.

Инструкция по эксплуатации

The Alpha-5 actuator operates automatically in conjunction with a room thermostat. It is a Normally Open (NO) type actuator, meaning the valve is open when no power is supplied to the actuator. When power is applied, the actuator closes the valve.

• Автоматическое управление: The actuator receives signals from a connected room thermostat. When the thermostat calls for heat (or cooling, depending on system configuration), it will either supply or cut power to the actuator to open or close the associated valve, regulating the flow of heating/cooling medium to the specific zone.
• Функциональный дисплей: The actuator features a visual function display (often a small indicator pin or window) that shows its current state (open or closed). Refer to the manufacturer's specific instructions for interpreting the display.
• First-Open Function: This feature allows the valve to remain open during initial system filling or commissioning, even without electrical connection, simplifying the startup process.

No manual intervention is typically required for daily operation once the system is properly installed and configured with a room thermostat.

Обслуживание

The Alpha-5 actuator is designed to be maintenance-free under normal operating conditions. No routine user maintenance, lubrication, or cleaning is required.

• Уборка: If necessary, the exterior of the actuator can be wiped with a soft, damp Ткань. Не используйте абразивные чистящие средства или растворители.
• Инспекция: Periodically inspect the actuator and its connections for any visible damage or loose wiring.

For any issues beyond simple visual inspection, it is recommended to contact a qualified HVAC technician.
