SeaChange controller can serve six underfloor heating zones

05 August, 2007

A new SeaChange controller for underfloor heating can provide independent temperature control of heating zones in underfloor heating schemes. This controller, from SC Controls, operates with a SeaChange control system to deliver a demand-based environment. This level of integration ensures boiler plant and associated heating pumps operate only when there is a demand from the heating zones.

Presence detection avoids wasteful lighting

05 August, 2007

A ceiling-mounted presence detector that can be surface- or flush-mounted onto a British Standard switch box has been introduced by CP Electronics. The SPIR-F/C detector monitors the zone and switches on automatically when occupancy is detected and off a preset time after the area has been vacated. The time delay can be adjusted from 10 s to 30 min. If there is sufficient natural light, a built-in photocell keeps the lighting off.
