T-4100-2 Johnson Controls Thermostat

Overview

The Johnson Controls T-4100-2 is a professional-grade, single-temperature pneumatic room thermostat engineered for individual space temperature control in commercial HVAC systems. Featuring a vertical-mount configuration, this reverse-acting, non-relay device utilizes a bimetal sensing element to modulate branch pressure, providing low-volume proportional output to control pneumatic valves and damper actuators.

Features

• Single temperature control with low-volume proportional output.
• Reverse-acting operation that responds accurately to temperature changes.
• Vertical mounting design ensures proper internal component alignment.
• Features exposed or concealed setpoint adjustments and a standard thermometer.
• Streamlined design requiring only a single air connection when used with a remote restrictor.

Specifications

• Type: Reverse Acting, Non-Relay Pneumatic Thermostat
• Mounting: Vertical Wall Mount
• Setpoint Range: 55 to 85 degrees Fahrenheit
• Supply Air Pressure: 13 to 25 psig
• Air Consumption: 45 SCIM with a 0.007-inch restrictor, or 25 SCIM with a 0.005-inch restrictor
• Connection Size: 5/32 inch barbed connection

Applications

• Used for individual space temperature regulation in commercial and industrial building automation systems.
• Suitable for heating and cooling applications requiring stable control within pneumatic networks.
• Designed to accurately modulate pneumatic valves and damper actuators in response to zone load changes.
