Description

ACI A/DIFF-ENT : Enthalpy, Differential Enthalpy Changeover Control, Indoor vs Outdoor, 24 VAC Form 1C Relay Contact, Altitude 0K to 2K ft

The A/DIFF-ENT is an enthalpy controller used to monitor indoor and outdoor temperature and humidity before converting them into a relay output with the 24 VAC/VDC supply voltage sourced through the relay contacts when reaching its internal trip points. The supply voltage to the A/DIFF-ENT is common to both the N/O or N/C contacts of the 10A Form C relay.
