The ETM-3051T is a direct digital thermostat controller that provides integrated control of unitary, packaged, and staged HVAC equipment - such as rooftop units.
The ETM-3051T is designed for applications that require two stages of digital heating/cooling control, a fan, and damper operations. It uses NovarNet™ protocol and is ideal for upgrading from conventional thermostats to fully distributed digital control.
Surface-mount in a RTU control panel or optional enclosure, using four slotted screw holes.
