Johnson Controls T-3610-1002 Pneumatic Low Limit Controller 18" Rigid Stem

The Johnson Controls T-3610-1002 is a pneumatic low limit controller designed specifically for unit ventilator applications. This controller provides reliable freeze protection by monitoring air temperature and shutting down the unit when temperatures drop to unsafe levels.

Key Features:

• 18-inch rigid stem element for accurate temperature sensing in airstreams
• Pneumatic operation - no electrical power required for reliable operation
• Plastic mounting bracket included for easy installation on unit ventilators
• Series T-3610 design engineered for HVAC freeze protection applications
• Durable construction for long-term performance in commercial and institutional buildings

This low limit controller is an essential safety device for unit ventilators, preventing coil freeze-up during cold weather operation. The extended 18-inch stem allows proper placement in the discharge airstream for accurate temperature monitoring. The pneumatic control system provides fail-safe operation independent of electrical power, making it ideal for critical HVAC applications in schools, offices, and other commercial facilities.
