Emerson Alco 097882 Temperature Control

The Emerson Alco 097882 Temperature Control (Model TS1-C0P) is a heavy-duty single stage thermostat engineered specifically for critical frost protection in high-demand refrigeration and heat pump systems. As a veteran-preferred HVAC freezestat, this unit features a 20-foot capillary tube that utilizes a vapor charge to detect the coldest point along the element, ensuring comprehensive coverage of large coil surfaces. With a field-adjustable range of 40°F to 68°F and a fixed 5°F differential, it provides precise commercial low limit control to prevent water coil rupture and expensive system downtime. The integrated SPDT switch is rated for 24FLA at 120/240VAC, allowing contractors to handle most inductive loads directly without needing auxiliary relays. Designed with an auto reset function, the TS1-C0P resumes operation once temperatures rise above the setpoint plus differential, making it ideal for defrost termination and space temperature monitoring where manual intervention is not feasible after every trip.

Key Benefits

• Superior 20' sensing element provides maximum surface area protection for HVAC coils against stratification.
• Robust SPDT electrical contacts ensure reliable switching for compressors, fans, or alarm circuits.
• Automatic reset logic streamlines maintenance by restoring system flow once safe operating temperatures are reached.
• Non-ambient sensitive design prevents nuisance tripping caused by temperature fluctuations at the control head.
• Lockable range and differential settings prevent unauthorized field adjustments, maintaining system HVAC safety limit integrity.

Common Questions

How should the capillary be installed to prevent false trips?
To avoid nuisance alarms from air stratification, the element should be "snaked" horizontally across the downstream side of the heating coil or upstream of the cooling coil, ensuring at least one foot of capillary is exposed to each square foot of coil area.

Can this unit replace a manual reset freeze stat?
While the 097882 functions as a low-limit safety, its auto reset feature differs from manual models like the TS1-D0P. Check your local mechanical code to ensure automatic restoration is permitted for your specific air handler application.

What is the benefit of the vapor charge in this Emerson Alco model?
The vapor charge ensures the control always responds to the coldest point anywhere along the entire 20-foot length, which is crucial for identifying localized freezing spots on large commercial coils.
