Siemens 192-205 Pneumatic Thermostat Dual Setpoint Day/Night Reverse Acting

The Siemens 192-205 is a pneumatic thermostat designed for HVAC control systems requiring dual setpoint capability with day/night scheduling. This reverse acting thermostat operates on 18-25 PSI pneumatic pressure and features a temperature control range of 55-85°F, making it ideal for commercial building automation and climate control applications.

Key Features:

• Dual setpoint control for day and night temperature scheduling
• Reverse acting operation for heating applications
• Pneumatic operation at 18-25 PSI supply pressure
• Temperature control range: 55-85°F
• Powerstar series reliability for commercial HVAC systems
• No electrical power required - fully pneumatic operation

This thermostat is designed for use in commercial building automation systems where pneumatic controls are preferred or required. The reverse acting configuration means the output pressure increases as temperature falls below setpoint, making it suitable for heating control applications. The dual setpoint feature allows for automatic temperature adjustment between occupied (day) and unoccupied (night) periods, providing energy savings and comfort optimization.
