and normally closed (NC) terminals to ensure the circuit closes upon a temperature rise for cooling stages
subsequently altering the output speed of the driven component
High Amperage Capacity: The 75VA rating supports larger control circuits and prevents voltage sag in complex HVAC systems
making it the correct choice for specific process heaters or HVAC applications where a pre-purge cycle is either managed by another controller or not required by the firing sequence
Siemens Building Technology 192-220 Stat THPU32HP7Y and normally closed (NC) terminalsThe Siemens 192 220 is a professional grade pneumatic room thermostat designed for precision temperature regulation in commercial and institutional HVAC systems. This direct acting (DA), single setpoint controller utilizes a highly sensitive bimetal sensing element to provide proportional control of pneumatic valves and damper actuators. Operating on a 1 pipe system architecture, this unit is engineered for low air capacity applications where a steady
