Baypayo 230V NC Electrothermal Actuator

The Baypayo 230V NC Electrothermal Actuator is an electrically controlled actuator designed to open and close compatible heating and HVAC valves automatically.

With a 230V AC power supply, Normally Closed (NC) operating principle, M30 x 1.5 mm connection and IP54 protection rating, the Baypayo actuator is particularly suitable for automatic zone control applications.

It is commonly used on underfloor heating manifolds, where individual heating circuits need to be controlled according to room temperature. It can also be used with suitable valves and manifold systems in radiator heating, Heat Interface Units (HIUs), fan coil systems and other HVAC applications.

The actuator provides the connection between the electrical control system and the hydraulic valve. A room thermostat or building control system can send a control signal to the actuator, allowing the corresponding valve to open or close according to the heating or cooling requirement.

Key Features of the Baypayo Actuator

The Baypayo actuator has been designed for heating and HVAC systems where reliable automatic valve control is required.

230V AC Operating Voltage

The actuator operates with a 230V AC power supply.

This makes it suitable for heating control systems designed around a 230V electrical infrastructure, including underfloor heating control panels and other zone-control applications.

When selecting an actuator, the system voltage must always be checked to ensure compatibility with the control equipment.

The Baypayo 230V actuator is designed specifically for applications requiring a 230V AC actuator.

Normally Closed (NC) Operation

The Baypayo actuator is a Normally Closed (NC) actuator.

In an NC system, the associated valve remains closed when the actuator is not energized. When the control system calls for heating, electrical power is supplied to the actuator, causing it to operate the valve and allow flow through the corresponding circuit.

This operating principle is particularly useful in underfloor heating zone control.

For example, when the room temperature falls below the setpoint, the room thermostat generates a heating demand. The control unit energizes the relevant actuator, which opens the valve on the underfloor heating manifold.

When the required room temperature is reached, the heating demand is removed and the actuator returns the valve to its closed position.

M30 x 1.5 mm Connection

The Baypayo actuator features an M30 x 1.5 mm connection.

Connection compatibility is one of the most important points when selecting an actuator. An actuator should only be installed on a compatible valve body or manifold valve.

The M30 x 1.5 mm connection enables the Baypayo actuator to be used with compatible valve bodies designed for this connection standard.

Before installation, the valve manufacturer's specifications and thread dimensions should always be checked.

H3: IP54 Protection Rating

The Baypayo actuator has an IP54 protection rating.

IP54 indicates that the enclosure provides protection against limited dust ingress and water splashing from applicable directions.

This is an important characteristic for heating and HVAC installations, where equipment may operate in technical rooms, manifold cabinets and other installation environments where moisture or water splashes may occur.

The actuator should nevertheless be installed according to the manufacturer's installation requirements and should not be exposed to conditions beyond its specified protection rating.

Compact Design

The Baypayo actuator has a compact housing designed for installation around valves and manifolds where space can be limited.

Compact dimensions are particularly valuable on underfloor heating manifolds, where several actuators may be installed next to each other.

A practical actuator design also makes installation and maintenance easier when multiple heating circuits are controlled from the same manifold.

Electrical Control of a Hydraulic Valve

The main purpose of an electrothermal actuator is to convert an electrical control signal into mechanical movement of the valve.

In a typical underfloor heating application, the control sequence can be represented as:

Room Thermostat → Control Unit → Electrothermal Actuator → Manifold Valve → Heating Circuit

The thermostat determines whether the room requires heat, while the actuator operates the corresponding valve.

This allows the heating system to respond automatically to changing room temperatures rather than relying on manual valve adjustment.

Advantages of an Electrothermal Actuator in Heating Systems

An actuator is a relatively small component, but it plays an important role in modern zone-controlled heating systems.

Without automatic valve control, the user would have to manually adjust individual heating circuits. With actuators, the heating system can respond automatically to signals from thermostats and control systems.

Individual Zone Control

Modern buildings often require different temperatures in different rooms.

For example, a living room may require a different temperature from a bedroom, office or unused room.

An actuator installed on each manifold circuit makes individual zone control possible when combined with suitable thermostats and control equipment.

Automatic Heating Demand

When a thermostat detects that the room temperature is below the desired setpoint, it can activate the corresponding actuator.

The actuator then opens the associated valve, allowing the heating medium to flow through the circuit.

When the heating demand ends, the actuator closes the valve according to the system's control logic.

Integration with Heating Automation

Electrothermal actuators are an important part of modern heating automation.

They can work as part of a larger control system consisting of:

• Room thermostats
• Underfloor heating manifolds
• Heating control centers
• Zone controllers
• Heat Interface Units
• Building automation systems
• Heating and cooling control systems

This makes the actuator more than just a valve accessory; it becomes part of the complete temperature-control system.

Where Is the Baypayo Actuator Used?

The Baypayo 230V NC Electrothermal Actuator can be used in a variety of heating and HVAC applications when installed with compatible valves and control equipment.

Underfloor Heating Manifolds and Room Thermostats

One of the most common applications for this type of actuator is underfloor heating.

An underfloor heating manifold distributes heated water to individual circuits serving different rooms or zones.

Each circuit can be controlled by an actuator.

A typical system works as follows:

Room Thermostat → Wiring Centre / Control Unit → Baypayo Actuator → Manifold Valve → Underfloor Heating Circuit

When the room requires heat, the thermostat sends a signal to the control unit. The control unit energizes the relevant actuator and the actuator opens the corresponding manifold valve.

This allows each room to be controlled independently.

For multi-room residential projects, hotels, offices and commercial buildings, this provides a practical way to create individual heating zones.

Heat Interface Units and Actuated Manifolds

The Baypayo actuator can also be incorporated into heating systems using Heat Interface Units (HIUs) and actuated manifolds.

In apartment buildings and other hydronic heating installations, individual circuits may need to be controlled according to room temperature or system demand.

When combined with a suitable manifold valve and control system, the actuator can automatically regulate the flow to the relevant heating circuit.

This is particularly useful where the heating system is designed around individual apartment or room-level temperature control.

Radiator Heating Systems

Electrothermal actuators can also be used in suitable radiator heating applications where automatic valve control is required.

Instead of manually adjusting a valve, the heating system can use a thermostat or automation controller to operate the actuator.

This approach can be useful in buildings with multiple heating zones, where different areas need independent temperature control.

Fan Coil and HVAC Systems

Actuators are also used in heating and cooling systems, including suitable fan coil and hydronic HVAC applications.

In these systems, the actuator can control a compatible valve to regulate the flow of hot or chilled water.

The control signal can come from a thermostat, room controller or building management system, depending on the system architecture.

The exact valve type and actuator application should always be selected according to the HVAC system design.

Automatic Valve Control

The fundamental purpose of the Baypayo actuator is automatic valve control.

Instead of manually opening or closing a valve, the actuator allows the valve to be operated automatically in response to a control signal.

This makes it suitable for:

• Underfloor heating zone control
• Heating manifolds
• Radiator systems
• Heat Interface Units
• Fan coil systems
• Hydronic heating systems
• Hydronic cooling systems
• HVAC zone control
• Building automation applications

Why Choose the Baypayo Actuator?

Choosing an actuator is not simply a matter of comparing voltage and connection dimensions.

In a modern heating project, the actuator may work together with thermostats, manifolds, valves, Heat Interface Units, heat meters, water meters, communication systems and software.

For this reason, system compatibility, engineering support, service and long-term technical assistance are just as important as the actuator itself.

Baypayo Technology

Baypayo develops solutions across heating control, metering, automation and building energy technologies.

This broader technology background makes it possible to evaluate the actuator as part of a complete heating system rather than as an isolated component.

A project can combine products such as:

Heat Interface Unit + Heating Manifold + Electrothermal Actuators + Room Thermostats + Heat Meters + Meter Reading Software

This integrated approach can simplify project planning and technical coordination.

One Manufacturer for Multiple System Components

One of the key advantages of working with Baypayo is the ability to source complementary products from the same technology and manufacturing organization.

Instead of purchasing the actuator from one supplier, the thermostat from another, the manifold from another and the metering system from yet another supplier, project requirements can be evaluated as a complete system.

This can be particularly valuable for:

• Property developers
• Contractors
• Mechanical installation companies
• Heating system installers
• HVAC contractors
• Wholesalers
• Large residential projects

A coordinated product portfolio can reduce compatibility concerns and simplify technical communication during installation.

Integration with Software and Digital Systems

Modern heating systems increasingly combine physical equipment with digital monitoring and management.

Baypayo's product portfolio includes meter reading, remote monitoring, heat cost allocation and software-based solutions.

This creates an opportunity to combine heating equipment with measurement and digital management systems within a broader project architecture.

The actuator itself performs the physical valve-control function, while thermostats, controllers, meters and software can provide the monitoring, measurement and management functions required by the overall system.

This system-oriented approach is especially valuable in large residential and commercial projects.

Engineering Support

Selecting the correct actuator is only the first step.

The actuator must also be compatible with the valve, manifold, control unit and electrical architecture of the installation.

Baypayo's engineering-oriented approach can help project teams evaluate the complete system and select appropriate products according to the application.

For contractors and mechanical installation companies, this means having technical support not only for the individual product but also for the overall heating and control solution.

Baypayo Service and Technical Support

After-sales service is particularly important for heating and HVAC products because these systems are expected to operate continuously over long periods.

A problem in a heating system may involve several interconnected components.

For example:

Thermostat → Control Unit → Actuator → Valve → Manifold → Heat Interface Unit

If products are supplied by different manufacturers, identifying the source of a problem can require communication with several companies.

With a system-based Baypayo solution, the customer can benefit from a more coordinated technical support approach.

The objective is simple:

One technical partner for a complete heating solution.

This can provide an important advantage for projects where fast troubleshooting and coordinated technical support are critical.
