Wall controls — Jung KNX

Brand: Jung. Room-by-room switch plan: positions.

Operating concept

Three tiers.

F 50 room controllers

Models: LS 5292 D 1ST 2-gang / LS 5294 D 1ST 4-gang, Secure. Per-room thermostats + manual climate control + complex-scene buttons in every climate room.

  • Physical layout (verified, Jung install sheet): full-height central display flanked by two button columns — 2-gang = 2 bar buttons per side (4 total), 4-gang = 4 per side (8 total); one or two functions per button, buttons pairable as rockers; module fills one frame position (DIN 49073 box) and is completed with a separate button cover kit (..502 / ..504 TSA, finish-dependent).
  • Verified capabilities: two independent controller circuits; heating+cooling with auto changeover and additional stages; fan control auto + manual levels (up to 8); wired external NTC probe input (FF NTC, cable up to 50 m); native underfloor-heating temperature limit; alarm function with button acknowledge; RGB status LEDs with night reduction via bus object; display pages incl. up to 3 "any temperature" bus values (e.g. floor probe).
  • RC button policy: minimal climate footprint — climate claims only the setpoint + / − pair (the single-press daily gesture); mode, AC-fan override, and temperature views live in the RC's built-in select/adjust menu (entered by pressing the top two buttons together; ETS-trimmed to the wanted items); no dedicated mode or fan buttons anywhere (fan policy).
  • Gang count per room by scene-slot demand — 2-gang = setpoint pair + 2 slots, 4-gang = setpoint pair + 6 slots (the display RC exists only as 2- or 4-gang); slots = Scene-TBD per the scene policy; decided room by room in the positions register.
  • To verify: engraving/labeling options for F 50 button sets (F 40 engraving is confirmed).

F 40 push-buttons

Non-RC, 429x 1ST + TSEM extensions — lights / curtains / blinds and some local scenes at secondary positions. Big engraved full-surface buttons, up to 3 functions each (two pressure points + full-surface); red status LEDs (no RGB), night brightness reduction, alarm flash.

Exterior push-buttons

The standard F 40 is not selected for exterior positions: JUNG does not document the LS 429x 1ST as suitable for outdoor exposure. Unspecified protected (weatherproof) push-button(s) for now at the two exterior positions — the BBQ-zone counter (zone 8) and a wall group in the chill zone (zone 22). Product, mounting form, capacity, and control concept: TBD with the contractor.

  • Protection follows exposure: the BBQ counter is sheltered from all rain but sits at an outdoor-kitchen counter near a sink, so IP44 is the minimum rating; higher is acceptable for splashes and cleaning. Its physical envelope and rough-in reserve two standard frame positions. The chill-zone group sits in an uncovered wall position exposed to direct rain, so the selected switch must be IP66 or higher. Its physical envelope and rough-in reserve two adjacent boxes/positions now; if the selected device ultimately needs only one, the second remains covered/reserved while maintaining IP66-or-higher protection.
  • Conventional floating-contact push-buttons would additionally require a KNX push-button interface in a dry protected location — device, location, and cable route TBD.

LS Touch floor hubs

2× LS Touch — one per floor: cross-zone climate overview and occasional adjustment, wet-room floor setpoints, shading/ventilation supervisory pages, whole-floor/house scenes. Hubs are UI only — all control loops stay distributed (room devices / heating actuator channels).

  • Verified capabilities (Jung product page, LS 459 D 1S): integrated room temperature sensor, room-temperature control with setpoint adjustment, FF NTC external probe input, alarm function, proximity + brightness sensors, up to 32 functions; not confirmed: a second independent controller circuit or a native underfloor limit (the F 50's strengths).
  • Ground-floor hub: kitchen 2.1, back-to-back with living-room 3.2 through the shared wall (host room = kitchen); the living room is covered by an F 50 RC at its 3.2 position instead.
  • First-floor hub: corridor 10.1 (stairs cluster, east wall; host room corridor).

Parked: HA control panel

Not a KNX tier and not part of the drilling decision. Whether the house gets a wall-mounted HA dashboard (tablet or dedicated panel) at all is TBD; if it happens, the server room (4) is the likely home (positions). What it would need when it lands: a flush box or recess, a mains feed, and a Cat6 drop.

Mounting heights

Mounting-height convention: all quoted heights are centerlines above finished floor, measured at the center of the group — a group being the units sitting at one height at one wall spot, single module or multi-position frame alike. A 3-position vertical frame quoted at 105 cm therefore sits at ~112 / 105 / 98 cm (71 mm pitch), its middle position on the quoted line — as at living-room 3.1.

Principle: two dedicated heights — a thermostat height for climate units (F 50 RC, LS Touch) and a switch height for push-button units; satellite/announcer provisions at switch level (voice owns the two terms).

  • Default values: 150 cm thermostat (the Jung-recommended RC height) / 105 cm switch.
  • A group above a counter, table or nightstand takes a position-specific height set by the furniture below: kitchen 2.3's F 40 — 110 cm · the BBQ-zone counter candidate (zone 8) — 110 cm · boudoir 12.2 — 90 cm · master-bedroom bedsides 14.2 and 14.3 — 70 cm · kid's-bedroom bedside 17.2 — 70 cm · kid's-bedroom desk 17.3 — 85 cm · Ekaterina's office 18.2 — 85 cm.
  • One thermostat-height exception: kitchen 2.3's F 50 sits at 160 cm — a decorative border conflicts with the 150 cm center, and this F 50 clears it above. This moves no other upper group, the ground-floor LS Touch included.
  • Diagram shorthand: position diagrams label each height line with its value (105 cm, 150 cm, 160 cm, …); this section is the single source of truth for the defaults and the per-position exceptions.
  • Climate devices carry no light/blind controls — climate and lighting vocabularies stay on separate units at separate heights.

Frame alignment

Vertical stacks centered on the group height — the stack's center on the quoted line, frames growing symmetrically above and below it (71 mm pitch → a 3-position stack at 105 cm sits at ~112/105/98 cm, a 2-position stack at ~108.5/101.5 cm).

  • Module order top→bottom: interior lights first (most-used at the top), then street/mechanics, satellite/announcer provisions last.
  • Horizontal rows (all modules at the switch height) remain a per-position option where the wall suits it — order convention then: most-used nearest the door jamb; width check vs. trim required (~223 mm for 3 positions).
  • Within one frame, extra buttons come as TSEM extension modules (no own bus coupler, cheap); a separate bus-coupled device only at physically separate positions.

Scene vocabulary

No scene is approved yet. Every scene slot in every button map is a Scene-TBD placeholder until its scene is approved — including the whole-house slots at the daily entrances (living-room 3.1, back-hallway 1.1). Scene-store (slap-hold / long-press save) stays disabled unless deliberately enabled per position.

Finishes

Shortlist (not final): LS 990 metal, LS 990 Les Couleurs Le Corbusier, LS ZERO. LS ZERO rough-in, verified from JUNG's installation overview and plastering-frame data: it uses standard flush boxes to DIN 49073, not proprietary boxes, but requires dedicated PA 98.. plastering frames/adapters with plaster aids to produce the flush transition. The exact adapter must match the frame size and finished plaster/plasterboard build-up, so the finish choice must be frozen before plastering.
