Johnson Controls T-4000-610 Adaptor

The Johnson Controls T-4000-610 is a specialized pneumatic thermostat conversion kit engineered for field technicians upgrading legacy systems. This bakelite back adaptor is specifically designed to facilitate the transition of single-temperature vertical instruments?such as the T-400 series thermostats and H-100 series humidistats?to modern T-4000 or H-4100 series infrastructure. By utilizing the existing bakelite housing, this kit streamlines the HVAC pneumatic instrument retrofit process without requiring complete wall surface reconstruction.

Built for durability in commercial environments, the T-4000-610 adaptor plate includes a pipehead adaptor to maintain pneumatic circuit integrity. It is compatible with both flush and surface-mounted pipeheads, ensuring a secure pneumatic control system upgrade. Contractors can rely on the precision-molded bakelite construction to provide a stable, non-conductive mounting surface for internal components, ensuring long-term alignment and performance for single temperature pneumatic thermostats.

• Direct Retrofit Compatibility: Specifically engineered to convert T-400 series vertical instruments to T-4000 series using the original mounting footprint.
• Reduced Installation Labor: Eliminates the need for replacing the entire backplate, significantly shortening the pneumatic thermostat installation timeline.
• Integrated Pipehead Adaptor: Includes essential components to bridge one pipehead adaptor configurations with modern sensing elements.
• High-Durability Construction: Heavy-duty bakelite ensures HVAC control component stability against temperature fluctuations and mechanical wear.

Can the T-4000-610 be used for dual-temperature thermostat upgrades?
No, this specific model is designed for single-temperature vertical instruments. Dual-temperature applications typically require the T-4000-611 variant.

Does this kit include the thermostat cover?
The T-4000-610 focuses on the internal adaptor and pipehead connection. Vertical mounting covers and the actual thermostat body must be sourced separately based on the specific application requirements.

Is this compatible with humidistat conversions?
Yes, it is the standard adaptor kit for upgrading H-100 series humidistats to the newer H-4100 series models.
