Specifications

  • Type: Pneumatic Room Thermostat Kit Direct Acting

    Product Overview:
    Regulates room temperature in pneumatic HVAC control systems by adjusting air pressure signals to connected control devices. The Schneider Electric (Barber Colman) 2212-618-1 is a direct-acting pneumatic room thermostat kit designed for proportional temperature control. It responds to changes in room temperature and adjusts the pneumatic control signal to support the operation of connected valves and damper actuators. The kit provides a thermostat and associated conversion components for pneumatic temperature-control applications.

    Temperature Regulation:
    Responds to room temperature changes through a mechanical sensing element that influences pneumatic control pressure. This temperature-responsive operation allows the thermostat to adjust its output as room conditions move away from the selected setting. Proportional control supports gradual adjustments to connected HVAC devices rather than relying solely on basic on-off switching.

    Pneumatic Signal Control:
    Regulates the pneumatic output supplied to connected control devices according to the thermostat's direct-acting response. Changes in room temperature influence the branch air pressure, which can control pneumatic valves and damper actuators. This operation supports coordinated regulation of heating and ventilation equipment within pneumatic HVAC systems.

    Replacement Guidelines:
    Replace the Schneider Electric (Barber Colman) 2212-618-1 Pneumatic Room Thermostat Kit when the thermostat or its associated components show physical damage, deterioration, or a confirmed functional fault affecting temperature regulation or pneumatic output. Inconsistent pressure response, failure to maintain the intended room temperature, or damaged tubing connections may indicate that the assembly requires inspection. Check the thermostat and conversion components to identify the source of the control problem.

    Common Failure Symptoms:

    • Room temperature does not respond appropriately to thermostat adjustments.
    • Connected pneumatic valves or damper actuators fail to respond correctly to control signals.
    • Branch air pressure becomes inconsistent during thermostat operation.
    • Temperature regulation becomes unstable or inaccurate.
    • Visible damage or deterioration affects the thermostat, tubing, or connection components.

    Equipment Compatibility:
    The 2212-618-1 is identified as a two-pipe direct-acting pneumatic thermostat conversion kit. It is intended for pneumatic HVAC control arrangements using compatible pneumatic valves and damper actuators. Verify the existing thermostat configuration, air-line connections, mounting arrangement, and control requirements before selecting the kit. Confirm the conversion requirements against the equipment's installation documentation.

    Customer Questions
    What is the Schneider Electric 2212-618-1 pneumatic thermostat kit used for?

    It provides proportional room temperature regulation in pneumatic HVAC systems used for heating, ventilation, and air conditioning.

    How does direct-acting operation affect pneumatic output?

    In direct-acting operation, pneumatic output pressure increases as the sensed room temperature rises.

    Which HVAC devices can this thermostat kit operate?

    It is designed for proportional control of compatible pneumatic valves and damper actuators.

    What should be inspected during pneumatic thermostat maintenance?

    Inspect the air tubing, fittings, and connections for leaks, blockages, or physical deterioration that could interfere with pneumatic signal transmission.

    When should a pneumatic room thermostat kit be replaced?

    Replacement may be necessary when functional testing confirms that the thermostat cannot maintain reliable temperature-responsive pressure control.
