Digital Enclosure Control
DEC4 TM – that’s Digital Enclosure Control, fourth
Generation – is the brain of your Tempest enclosure. It will
maintain the internal environment in a comfortable
temperature and humidity range, and prevent
condensation – the real killer of outdoor equipment. DEC4
monitors internal and external temperature, humidity and
lamp current at all times, and uses this information to
control the enclosure’s lamp relay, fan(s) and heater(s). It
can report back over an RS485 network, using the RDM
protocol (Remote Device Management), or connect to
your TCP/IP network for remote monitoring amd
management using Tempest’s TEMP protocol.
