Product Description
SmartNode SD.4FDNH Smart Module
Combine fan speed, light dimming and two types of switching in one four-output module.
What this configuration is for
A compact room can allocate the fan output to its ceiling fan, the dimmer to compatible ambient lighting, the normal output to a switched light and the heavy output to a suitable appliance. Each channel must keep its assigned load type.
Daily control and automation
The module connects to a 2.4 GHz Wi-Fi network and supports Smart Node app control, with Alexa and Google Home integrations. It can work with supported traditional switches or capacitive panels, so the wall control remains part of the installation. A configured timer can automate load shutoff, and up to 25 saved schedules can continue without internet. Remote access and voice services still need their applicable network connections. The dedicated fan channel provides five speed steps; confirm the connected fan accepts this form of regulation rather than assuming support for a BLDC fan. The dimming outputs use TRIAC phase-cut control; Smartnode specifies leading-edge operation. Use compatible dimmable drivers and check low-level performance with the actual fittings.
Installation and load planning
A licensed electrician must check the wiring diagram, switchboard clearance and each circuit before installation. The stated wattages are output-type maxima, not a verified combined-load allowance. Respect the separate LED-count limits and confirm load suitability, including starting current. Keep the module dry and isolate the supply before wiring. Legacy SmartNode model names do not establish an interchangeable replacement.
