T-3300-1

Designed for precise temperature monitoring, the Johnson Controls T-3300-1 is a pneumatic thermostat utilized in various HVAC systems. Its lightweight build, at 2.6 lbs, makes it relatively easy to handle during installation. The thermostat features a dual-operational capability, acting directly at 15 psig and reversing at 20 psig, ensuring flexibility in managing temperature control.

The thermostat incorporates a remote bulb sensing element for enhanced accuracy of readings, allowing it to effectively control the return-air temperature in terminal air conditioning units. Setting temperature levels is straightforward, thanks to the external 'Cool-Warm' adjustment dial.

With a maximum supply pressure of 25 psig (172 kPa), this thermostat is designed to perform efficiently under various pressure conditions. The operational temperature range spans from -29°C to 66°C, accommodating a variety of environmental settings. Air connections are made simple through a 1/4 in. barbed fitting, promoting ease of installation and compatibility in existing setups.

Additionally, the T-3300-1 includes a capillary tube measuring 42 inches and consumes only 1.5 standard cubic feet per minute (scfm) during operation, appealing for applications where air efficiency is a consideration.
