X2 Round Wall Screen

Name: X2 Round Wall Screen
Brand: FRANKCAS
SKU: FC-X2-WS4R-01

4-inch round touch control for scenes, colour and air quality

One screen per room, on the wall, with no app to install and nothing for the occupant to learn. Swipe between rooms, tap a scene, pick a colour on the wheel, or glance at the air page to see what the CO₂ is doing. Everything on the screen — which rooms it shows, which scenes, which sensors — is chosen in X2 under Commissioning › Wall Screens and pushed over the site network, so a screen can be re-purposed without coming off the wall.

Each screen needs the FRANKCAS X2 platform running on site (version 2.2.11 or later), 2.4 GHz Wi-Fi reaching the wall position, and a 220–240 V AC supply at the back box. Rooms, scenes, colour lights and air sensors are then assigned per screen in X2 — nothing is configured on the screen itself.

4" round IPS display, 720 × 720, 10-point capacitive touch
Up to 8 rooms per screen — swipe left and right between them
Up to 4 scenes plus Off per room, with active-scene feedback
RGB colour wheel with a brightness ring for colour lights
Air page: CO₂, temperature, humidity and AQI gauges
Works with Casambi and Tridonic sceneCOM (DALI-2 Part 303) air sensors
Clock screen saver with a warm, dimmed night mode
Firmware updates over Wi-Fi from X2, with automatic rollback
Password-protected connection to X2 — no cloud required

Mains connection: the screen runs on 220–240 V AC through an integrated 5 V PSU, so installation must be carried out by a qualified electrician in accordance with BS 7671. It also needs 2.4 GHz Wi-Fi reaching the wall position — worth checking before the bracket goes up.
