Emerson Alco 097885 Temperature Control

The Emerson Alco 097885 (Model TS1-D0P) is a heavy-duty freezestat temperature control engineered for critical frost protection in commercial HVACR systems. Designed as a high-limit safety, this manual reset thermostat features a 20-foot capillary sensor that detects the coldest point along its length, making it ideal for monitoring large heat exchanger surfaces. With a temperature range of 40-68 degrees F and a fixed 5-degree differential, it ensures precise system protection by interrupting the circuit before freeze-up occurs. The unit utilizes a robust SPDT switch rated for 120/240VAC and up to 24 FLA, allowing for direct control of most motors and solenoid valves without auxiliary relays. Built with a vapor charge sensing element, the ALCO TS1-D0P provides rapid response times and remains unaffected by ambient temperature fluctuations at the control head, ensuring reliable refrigeration safety control in demanding mechanical room environments.

• Extended Sensing Coverage: The 20-foot capillary provides comprehensive frost monitoring across large coils, identifying localized cold spots.
• High Load Capacity: Heavy-duty SPDT contacts permit direct switching of heavy electrical loads, simplifying wiring and reducing component count.
• Critical Safety Locking: Features a manual reset mechanism required for safety compliance, ensuring technicians must inspect the system before restarting.
• Environmental Stability: Non-ambient sensitive design prevents nuisance tripping even when the control body is exposed to extreme mechanical room temperatures.
• Installation Flexibility: Captive cover screws and a flexible capillary allow for quick mounting in various HVACR control configurations.

What is the reset type for the Emerson 097885?
The TS1-D0P is a manual reset control, requiring a physical intervention to restore system operation after a low-temperature trip.

Can this control handle inductive loads directly?
Yes, the heavy-duty SPDT switch is rated to handle up to 24 FLA and 144 LRA at 120/240 VAC, eliminating the need for a separate relay in most applications.

Is the capillary sensor ambient sensitive?
The Emerson Alco 097885 uses a vapor charge that senses only at the coldest point of the capillary, making it immune to ambient heat at the control bellows.
