Siemens Building Technology 193-218 Pneumatic Room Thermostat 2-Pipe R/A Heat/Cool

Siemens 193-218 is a pneumatic room thermostat that provides accurate temperature control in heating and cooling systems, and provides consistent performance in temperatures from 45°F to 85°F. Pneumatic principle based this thermostat to control HVAC equipment through air pressure. It has a dual set point system, meaning it is able to run independently at a heating or a cooling set point. ensures energy efficiency with little sacrifice in comfort, and the 193-218 system is designed for two pipe systems, and works with a broad span of conventional HVAC equipment, such as furnaces, air conditioners, and heat pumps.
