The RDC detects rainfall directly and triggers immediate window closing, providing consistent weather protection without relying on weather forecasts or manual checks.
Connects directly to the dedicated rain sensor input on Topp TF24 and TF44 controllers, making installation straightforward with no additional components.
The rain signal takes priority over all other commands (thermostatic, remote or timer), ensuring windows close whenever rain is detected regardless of other system states.
Detects rainfall on the sensor surface and sends a close signal to the controller within seconds, minimising any exposure of interior surfaces to rain.
Plugs directly into the rain sensor terminal on Topp TF24 and TF44 controllers: no relay, adapter or additional wiring block needed.
The rain sensor signal has the highest priority in the control hierarchy, overriding temperature-triggered opens, remote controls and time schedules.
IP65-rated enclosure is suitable for permanent outdoor installation on a roof parapet, window head or external wall.
Used in commercial, educational and residential buildings where automated window opening requires weather protection to prevent water ingress.
Particularly suited to roof-mounted vents and high-level windows that are difficult to close manually in the event of a sudden rain shower.
Detects rainfall and sends an immediate close signal to the connected controller, ensuring all ventilation windows close before water ingress can occur.
Designed to work directly with Topp TF24 (24V) and TF44 (230V) controllers via a dedicated rain sensor input: no additional interface required.
Weatherproof IP-rated enclosure is designed for external mounting on a roof, wall or window frame where it is exposed to the elements.
The rain sensor signal overrides any open command from the temperature controller or remote control, ensuring windows always close in wet weather.
