Robertshaw 9200H Thermostat

The Robertshaw 9200H Thermostat is a heavy-duty 24V mechanical thermostat designed for 1H/1C gas or electric systems. As a veteran-grade horizontal mechanical thermostat, the 9200H serves as the direct replacement for the Robertshaw PSM400SA and over 50 other competitive models. This unit features a mercury-free design, meaning no leveling is required during installation.
