T-8000-6 Johnson Controls Thermostat

Overview

The Johnson Controls T-8000-6 is a high-performance remote bulb element pneumatic controller designed to provide precise temperature regulation. This relay-type instrument is ideal for applications where extreme environmental conditions prevent the direct mounting of the controller or where manual adjustments would otherwise be inconvenient. It features a rugged design optimized for installation on local control panels or surfaces.

Features

• Flexible Action Options: Offers proportional sensitivity or two-position control, with field-selectable Direct Acting (DA) or Reverse Acting (RA) modes via a marked rail.
• Reduced Friction and Hysteresis: Built with flexure levers to ensure highly reliable operation and minimal mechanical wear.
• High Visibility: The built-in pressure gauge and setpoint dial remain easily visible directly through the unit cover.
• Adjustable Controls: Gain, proportional sensitivity, or two-position differential can be modified by repositioning the integrated sliding leakport slider.
• Factory Calibrated: Arrives pre-calibrated from the factory to streamline installation and minimize initial setup time.

Specifications

• Supplier Part Number: T-8000-6
• Sensor Type: 8-foot averaging element
• Capillary Length: 15-foot non-compensated capillary
• Temperature Control Range: Dual dials for -10 to 124 degrees Fahrenheit and 110 to 244 degrees Fahrenheit
• Temperature Scale: 2-sided Fahrenheit dial
• Factory Settings: Approximately 8 psig output pressure at 70 degrees Fahrenheit with a sensitivity of 1 psi per degree Fahrenheit (two-position model factory adjusted to a 4 degrees Fahrenheit differential)
• Mounting Type: Surface mount

Applications

• Remote temperature sensing in HVAC systems where the main controller must be protected from extreme space conditions.
• Commercial building automation and pneumatic control architectures.
• Dual-temperature control environments requiring high-precision proportional or two-position staging.
• Surface-mounted local control panel installations.
