The NT-550MIL is an advanced intelligent network thermostat that is ready for deployment in the harshest marine operating environments with an adjustable range of 13 degrees C (55 degrees F) to 29 degrees C (85 degrees F). The NT-550MIL is a powered, wired network capable, thermostat with digital local indication, independent control of heating and cooling space set points, and optional remote indication and control. 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 independent alarms when pre-set threshold conditions are exceeded. Two independently scheduled auxiliary relays are also supported to enable customers to control additional equipment.
It connects with a Cat-5 Ethernet cable for traditional installation and is enclosed in a MIL-SPEC aluminum housing. The thermostat meets the following qualifications: Shock, MIL-DTL-901, Grade A, Class I, Type A Vibration, MIL-STD-167-1, Type I EMI, MIL-STD-461, Surface Ships Certified.
