Carrier HH22AG106 Temp Control

The Carrier HH22AG106 Temp Control is an essential HVAC industrial thermostat designed for heavy-duty staging and limit applications. Operating with a 0-100F temperature range, this SPDT temperature control provides versatile terminal logic, allowing for both heating and cooling circuit integration or a common-off configuration. Featuring a 20-foot capillary tube, this mechanical control allows for remote sensing in air handlers, walk-ins, and complex duct systems where the controller must be mounted away from the sense point. As a direct OEM replacement part, it ensures the precise calibration required for commercial HVAC equipment, effectively replacing older units like the T675A-1805. The snap-acting switch mechanism provides reliable electrical contact during cycles, preventing typical pitting and ensuring consistent performance in demanding environments. Whether used as an outdoor air thermostat in series with gas valves or for HVAC system troubleshooting, this 0-100 degree temperature switch delivers professional-grade accuracy and long-term durability for every service truck.

• Wide Temp Range: The 0-100F sensing range is perfect for ambient lockout, low-limit protection, or moderate refrigeration staging.
• Extended Reach: A 20-foot capillary provides maximum mounting flexibility for remote sensing applications in large-scale airside systems.
• SPDT Switch Logic: The Single Pole Double Throw configuration allows for heating, cooling, or alarm-based terminal wiring.
• Factory Authorized Part: Designed as a specific Carrier replacement control, guaranteeing fitment and electrical compatibility without field modifications.
• Rugged Construction: Built to withstand commercial mechanical room conditions, ensuring the HVAC control board receives accurate signals for years.

Common Questions

What is the primary application for the HH22AG106? This temperature controller is frequently used as an outdoor air thermostat (OALT) to control staging on gas valves or as a freeze thermostat in air-handling units. Can the HH22AG106 replace a T675A series control? Yes, it is often utilized as a professional-grade replacement for the T675A-1805 series remote bulb thermostat, provided the amperage and range match the original specs. How should the 20-foot capillary be installed? The capillary tube should be routed carefully to avoid kinks. It is designed to sense temperature at the bulb end, making it ideal for remote temperature sensing in ducts or fluid tanks.
