ACI Automation Components A/DIFF-ENT Differential Enthalpy Control

Condition:

New / Unused, open box. Missing instruction sheet. There is no selector switch, which differs from some other models we’ve seen.

Here’s what we know about it:

The A/DIFF-ENT measures both temperature and humidity, providing a relay output based on these readings. It is engineered for enthalpy, differential enthalpy, and enthalpy changeover control.

Technical Specifications:

• Accuracy: ±1 BTU @77°F (25°C)
• Stability: Less than 2% RH drift over 5 years
• Sensitivity: 0.1% RH
• Repeatability: 0.5% RH
• Deadband: 1 BTU or 0.5°F (0.27°C)
