Elsner P03 KNX grupu adrešu konfigurācija

ETS6 parameter settings for Elsner P03-KNX-FLAT:

Twilight threshold:      50 lux (adjustable 1–200 lux)
Twilight hysteresis:     10 lux (prevents rapid cycling at threshold)

Group addresses (recommended scheme):
  GA 10/0/0 — Twilight bit       DPT 1.001  (1=dark, 0=daylight)
  GA 10/0/1 — Brightness lux     DPT 9.004  (0–100,000 lux)
  GA 10/0/2 — Wind speed m/s     DPT 9.005  (optional, if P03-KNX-WS)
  GA 10/0/3 — Rain alarm         DPT 1.001  (optional, if P03-KNX-WS)

Twilight logic:
  Lux < 50 lux for > 30 seconds → GA 10/0/0 sends value 1
  Lux > 60 lux for > 60 seconds → GA 10/0/0 sends value 0
  (hysteresis window 50–60 lux prevents hunting at sunset/sunrise)

Bāzes apgaismojuma DALI loģikas bloks no krēslas līdz rītausmai

Trigger: GA 10/0/0 (Twilight bit) = 1 (dark)
  → KNX DALI gateway: DALI Group 1 (Perimeter) → Scene 1
     Scene 1 = 20% brightness (DALI value 51/255)
  → KNX DALI gateway: DALI Group 2 (Parking) → Scene 1
     Scene 1 = 20% brightness (DALI value 51/255)
  → KNX DALI gateway: DALI Group 3 (Entrance) → Scene 2
     Scene 2 = 40% brightness (DALI value 102/255)
     (entrance requires higher base level for pedestrian safety)

Trigger: GA 10/0/0 (Twilight bit) = 0 (daylight)
  → DALI Group 1, 2, 3 → Off (DALI value 0)

Note: DALI scene commands are sent via KNX group addresses
  to the KNX-DALI gateway (e.g. Tridonic DALI-2 Gateway or
  ABB DALI Gateway DG/S 8.16.1) — not directly to luminaires.
  Gateway group address: GA 10/1/0 = DALI Group 1 scene command

KNX binārās ieejas vadu pieslēgums PIR sausajam kontaktam

KNX binary input: MDT BE-04000.02 or ABB SA/S 2.16.2.1

Wiring:
  PIR relay NO contact → Binary input terminal I1 (+)
  Binary input COM terminal → PIR relay common
  PIR power supply: 12VDC from panel PSU (separate from KNX bus)

ETS6 channel 1 parameters:
  Operating mode: Switch
  Contact type: Normally open
  Send on rising edge: value 1 (motion detected)
  Send on falling edge: value 0 (no motion)
  Group address: GA 10/2/0 — PIR Zone 1 motion
  Cyclic sending: disabled (edge-triggered only)

Note: do NOT connect PIR 12VDC supply to KNX bus terminals.
  KNX bus is 29VDC with current limits for bus devices only.

MDT loģikas moduļa konfigurācija kustības pastiprināšanai

Logic: AND gate (twilight AND motion)
  Input 1: GA 10/0/0 (Twilight bit = 1)
  Input 2: GA 10/2/0 (PIR Zone 1 motion = 1)
  Output:  GA 10/3/0 (Motion boost enable)

On GA 10/3/0 rising edge (motion boost trigger):
  → DALI Group 1 (Perimeter) → Scene 8 = 100% brightness
  → DALI Group 2 (Parking)   → Scene 8 = 100% brightness
  → Start 5-minute timer block (300 seconds)

On timer expiry (no new motion for 5 minutes):
  → DALI Group 1 → Scene 1 = 20% base level (return)
  → DALI Group 2 → Scene 1 = 20% base level (return)

Timer retriggering:
  Any new motion within 5 minutes → timer resets to 300s
  → prevents lights cutting off mid-motion

Device: MDT Timecontroller SCN-TC8.01 or Gira X1 time block

Monday–Sunday:
  Dusk (via twilight GA)    → base lighting ON at 20%
  02:00                     → GA 10/4/0 "Night economy" = 1
                               → DALI perimeter + parking → Off
                               → Entrance zone stays at 10% (safety only)
  05:00                     → GA 10/4/0 "Night economy" = 0
                               → Restore base 20% on twilight groups
  Dawn (via twilight GA)    → All outdoor zones → Off

Winter seasonal override (Nov–Jan):
  21:00 instead of dusk → avoid long energy-intensive winter nights
  05:00 instead of dawn → consistent morning ON time
  Reduce base level from 20% to 15% → Scene 5 (winter economy)

Note: twilight GA always takes priority over timer when
  daylight arrives unexpectedly (e.g. full moon, streetlight
  reflection) — use twilight bit as master enable, timer as
  override or economy reduction only.

Gada enerģijas ietaupījuma aprēķins — 10 × 50 W gaismekļi

Assumption: 3,500 night-hours per year, 10 × 50W luminaires

Constant 100% operation (no automation):
  10 × 50W × 3,500h = 1,750 kWh/year

With dusk-to-dawn base + PIR boost (no night-off):
  Base 20%:     10 × 10W × 3,500h × (1 − motion fraction)
  Boost 100%:   10 × 50W × 3,500h × motion fraction
  Assume 15% of night hours have active motion:
    Base:  10 × 10W × 2,975h = 297.5 kWh
    Boost: 10 × 50W ×   525h = 262.5 kWh
    Total: 560 kWh/year

With night-off 02:00–05:00 (3h per night):
  Night hours reduced by 3h × 365 = 1,095h
    Remaining: 3,500 − 1,095 = 2,405 hours base/boost
    Approx total: 385 kWh/year

Saving vs constant 100%:
  1,750 − 385 = 1,365 kWh/year (78% reduction)
  At €0.25/kWh: €341 saving per year for one parking zone
