What it is
The HC2.4 is a plug-in WiFi extender adaptor card made by Secure/Horstmann. It slots into the front of a compatible receiver to add remote, app-based control of the heating system over a 2.4GHz WiFi connection, with no separate gateway or hub required.
Signs this part needs replacing

- The adaptor card won't stay seated or connected in the receiver
Before you order
