Lighting controls in Wiltshire
Lighting controls switch or dim lights automatically based on occupancy, daylight or time. We cover Wiltshire, including Swindon, Salisbury and Trowbridge.
Lighting controls work in Wiltshire
Daylight dimming works best in premises around Wiltshire with deep window bays or roof lights.
In Wiltshire buildings, the quickest control savings usually come from presence detection in rooms that are used for only part of the day.
What's included
- DALI and DALI-2 systems with scenes and zoning
- Presence and absence detection for rooms, aisles and toilets
- Timeclocks and photocells for external lighting
- Daylight-linked dimming along windows and under roof lights
