The NT-550MIL is an advanced intelligent network thermostat which represents the culmination of customer feedback and committed research and development. We have developed a rugged, military networked thermostat that is ready for deployment in the harshest marine operating environments. The NT-550MIL connects with a Cat-5 Ethernet cable for traditional installation. It is enclosed in a MIL-SPEC aluminum housing and meets military standards for shock, vibration, and electromagnetic interference. Additionally, the NT-550MIL supports three external wired sensors which can be used to sense temperature or dry contact closures from external equipment. Each of these sensors can provide optional independent alarms via email or text message notification when pre-set threshold conditions are exceeded. Two independently scheduled auxiliary relays are also supported to enable customers to control additional equipment.
