Line-voltage mechanical thermostat
This Emerson 1609-101 is a line-voltage mechanical thermostat with a single SPST switch that closes on temperature rise. It operates across a control range of -30 to 90 degrees F and handles 120 to 240 VAC at up to 4.9 A full load. A remote sensing bulb is included and the dustproof NEMA 1 enclosure is finished in gray.
Cooling-only control for HVAC systems
The device suits installers who need a simple close-on-rise thermostat for cooling applications with remote sensing. It is not for heating circuits, multi-stage equipment or installations that require an open-on-rise action or multiple switch poles.
SPST close-on-rise switch action
The single-pole single-throw switch closes when temperature rises, which determines whether the thermostat matches the required control logic for the target cooling circuit.

Questions about this item
How often does the 1609-101 mechanical thermostat need recalibration?
The mechanical design has no factory calibration schedule; accuracy depends on the sensing bulb remaining clean and undamaged.
What limits continuous operation of the SPST switch at 240 VAC?
The 4.9 A full-load rating at 240 VAC is the limiting factor; exceeding it will overheat the contacts.
Does the dustproof NEMA 1 enclosure run hot or make noise during all-day use?
No moving parts or active cooling mean silent operation and negligible heat rise inside the enclosure.
