Enthalpy

The A/ENT-CTRL is an enthalpy controller which is used to measure temperature and humidty before converting them into a sourced relay output.  The supply voltage to the A/ENT-CTRL is common to both the N/O or N/C contacts of the 10A Form 1C Relay. (The A/ENT-CTRL-F1C's ouput acts as a dry contact rather than sourcing the supply voltage).  Each unit in this series features a coated circuit board and jumper selectable elevation setting.  The A/ENT-CTRL is covered by ACI's Five (5) Year Limited Warranty.
