WELLTHERM · CONNECTION & OPERATION

A suitable panel.
A complete combination.

Welltherm precon connects suitable connection components to the panel. Temperature controls complete the heating solution. We help you choose both parts together.

From panel to controllable warmth

The connector provides the electrical connection. The thermostat and any receiver handle heat demand and switching. These are different functions that must work together in your installation.

Welltherm panel

A version with power and mounting suited to the room.

Precon connection

The appropriate cable or connector for the selected panel and connection point.

Receiver & thermostat

Compatible controls for the temperature and times when you heat.

What makes precon practical?

On suitable panels, Welltherm uses a connection cable with a GST15i3 connector. Matching precon components make the connection clear and organised. Options include cables for a plug connection and a fixed connection, alongside separate connector components.

Our proposal specifies which panel, connection components and controls will be used together. This supports preparation for a new installation and makes later service enquiries more specific.

Start with your version

Not every Welltherm product has the same connection. A product series or production period may use a different cable, connector or mounting method. For an existing panel, start with its rating plate and original manual. A photo of the connection and the model number help us provide focused assistance.

The same connector does not mean the same controls

For a wireless system, the thermostat and receiver must work together within a suitable product combination. Alongside the connection, factors include the communication protocol and permitted electrical load. Time programmes, app control and window detection are features of specific controls; we list them only when the selected combination supports them.

The number of rooms also matters. Multiple panels in one room can follow a shared heat demand. Different rooms may require separate controls. We therefore tailor the component list to how the building is used.

What do we specify in your proposal?

  • The panel model and required power per room.
  • The connection method and suitable cables or connectors.
  • The thermostat, any receiver and desired control features.
  • The relevant manuals for mounting, connection and configuration.

Well prepared for installation

The connection, power supply and total load are assessed for the specific installation. A fixed electrical connection should be handled by a suitable installer. Follow the instructions for both the panel and the controls. A precon connector alone does not prove that a complete installation meets all applicable requirements.

We support professionals preparing a project and end users extending an existing system. Tell us your situation, product codes and control preferences so we can examine the combination in detail.
