Contact the Legom Technical Team to confirm exact specifications and select the correct model for your project.
How to Select the Right Base Station
Choosing the correct base station comes down to how many zones your system has, whether thermostat cabling is practical, and which thermostats and actuators you will connect. Before contacting the Legom team, confirm these three parameters from your heating design:
Number of heating zones
Count the independent thermostat-controlled rooms or areas in your system. The BS-Y6 handles 6 zones (12 actuators); the TCC and wireless models handle 8 zones (16 actuators). Each model allows up to 2 actuators per zone for larger rooms served by two manifold loops.
Wired or wireless communication
For new construction where signal cables can be installed during the build, choose a wired model (BS-Y6 or TCC). For renovations, retrofits, and heritage buildings where routing cable to each thermostat is impractical, choose the wireless 8-zone model, which uses RF communication and removes thermostat signal wiring.
Thermostat and actuator compatibility
All models work with standard 230V thermostats and NC thermal actuators, and integrate directly with Legom room thermostats and thermal actuators. Confirm your thermostat output and actuator load match the rated switching power of 2A / 200VA before installation.
Once you have these three values, the Legom engineering team can confirm the right model or initiate a custom development project for non-standard zone counts or voltages. Contact us via WhatsApp or info@legomsmart.com.

- ● Housing and branding: Housing specification, labelling, and LED indicator configuration can be adapted to suit your product line and brand.
- ● Sample and approval cycle: Samples are produced and tested against your specification before production commitment.
- ● Confidentiality: All OEM and ODM projects are handled under strict NDA.
Applications
Legom base stations are the central control hub wherever multiple heating zones must be managed from a single unit. By routing thermostat demand to the correct actuators and coordinating the pump and boiler, the base station replaces complex point-to-point wiring with one tidy, fail-safe controller.
Multi-Zone Underfloor Heating
The primary application. The base station connects room thermostats to the thermal actuators on the manifold, letting each room hold its own target temperature independently. Pair with Legom manifolds and thermal actuators for a complete system.
Hydronic Radiator Zone Control
Used as the control center for multi-room radiator systems where each zone is governed by a thermostat and a zone valve actuator, giving independent control across the property from one hub.
Residential and Light Commercial Systems
Integrated pump and boiler outputs let the base station manage the complete heating circuit, starting the pump and boiler only when a zone calls for heat. The 8-zone TCC suits larger homes, apartments, and small commercial spaces.
Renovation and Retrofit Projects
The wireless 8-zone model adds room-by-room control to existing buildings without running thermostat signal cables through finished walls and floors, cutting installation time and disruption.
Listed and Heritage Buildings
Where surface cable runs are not acceptable and concealed routing is restricted by preservation rules, wireless RF thermostat communication enables zone control with minimal physical intervention.
New Construction Installations
For new builds where cabling is installed during construction, the wired BS-Y6 (6-zone) and TCC (8-zone) provide a robust, cost-effective hub with screwless terminals for fast commissioning.
Frequently Asked Questions
A base station is the central wiring and control hub of a multi-zone heating system. It receives signals from room thermostats and routes switching commands to the corresponding thermal actuators on the manifold valves, opening or closing each zone based on demand. It also manages the pump and boiler outputs, starting the pump when any zone calls for heat and shutting everything down when all zones are satisfied. Without a base station, each thermostat would need to be wired independently to its actuator and to the boiler and pump circuit, which is far more complex and error-prone.
Legom is a manufacturer. Our base stations are produced at our own facility in Jiaxing, Zhejiang, China, with in-house PCB assembly, housing molding, terminal integration, and end-of-line functional and safety testing. We do not source finished units from third parties and resell them. Factory visits are welcome by appointment for clients who wish to audit the production process directly.
The difference is how the base station communicates with room thermostats. In the wired BS-Y6 and TCC, thermostat signal cables run from each room thermostat back to the base station through walls, floors, or conduit. In the wireless model, thermostat commands travel by radio frequency signal, removing these signal cables entirely. The actuator wiring from the base station to the manifold is the same in both. Wireless is preferred for renovations and retrofits; wired is preferred for new construction where cables can be installed during the build.
Match the model to the number of independent heating zones in your system. Choose the BS-Y6 for systems with up to 6 zones (12 actuators). Choose the TCC wired or the wireless 8-zone model for systems with 7 or 8 zones (16 actuators). The wired TCC and BS-Y6 use the same wiring concept, so an installation that grows beyond 6 zones can move up to the TCC with a familiar approach.
All models allow up to 2 actuators per zone. The BS-Y6 provides 12 actuator terminals across 6 zones; the TCC and wireless 8-zone models provide 16 terminals across 8 zones. Two actuators per zone is useful for larger rooms or open-plan areas where two manifold loops serve a single thermostat-controlled zone.
Legom base stations are configured for Normally Closed (NC) thermal actuators. In an NC system, the actuator is in its open (flow-on) position when no electrical signal is present and closes when energized by the thermostat. This means heating zones are active by default and the thermostat commands the system to stop heating once the target temperature is reached, the most common configuration for underfloor heating in Europe.
The 2-minute delay before the pump and boiler activate prevents the system from short-cycling during brief thermostat switching events and avoids conflicts between the base station's control logic and external water pump commands at startup. It protects the pump from repeated rapid start-stop sequences that reduce service life. A matching 2-minute follow-up time keeps the circuit running briefly after the last zone deactivates.
The wired models are compatible with standard 230V thermostats and NC thermal actuators, and integrate directly within the Legom HVAC ecosystem. The standard terminal connections and direct voltage supply also work with most third-party 230V heating control components. Verify that your thermostat output and actuator load match the rated switching power of 2A / 200VA before installation. For the wireless model, third-party thermostat compatibility depends on the RF protocol, so confirm with the Legom team before mixing brands.
No. The base station still requires a 230V mains power cable, and the actuators on the manifold are still wired to the base station. What is wireless is the communication between the room thermostats and the base station: thermostats transmit their demand by RF rather than through a signal cable. Each wireless thermostat will also need its own power source, typically batteries.
Legom base stations are built to the EN 60730-2 standard for automatic electrical controls, with an integrated cable guide and strain relief that is DIN EN 60730-1 compliant. Protection is IP20 with Class II insulation, suiting indoor installation in utility rooms, airing cupboards, and plant rooms beside the heating manifold. Compliance documents are available on request for project submission.
Yes. Legom offers full OEM and ODM customization including zone count, voltage rating, control direction (NC or NO), pump and boiler delay logic, wired or wireless communication, and housing and branding. All projects are handled under strict NDA. Contact the engineering team with your zone count, communication type, voltage, and control direction to begin.
