New old stock Minneapolis-Honeywell Da-Nite Agrathem thermostat marked T209A300X23X. The thermostat is unused and uninstalled but has not been operationally tested. The metal housing and dial have light storage and handling wear, and the original box is worn. The box label is partially ambiguous, so verify the T209A300X23X marking on the photographed thermostat and confirm suitability for the intended system before installation. Includes only the exact thermostat, box and paperwork shown in the eight photos.
