Idle AC Control

AC Request Input
Input channel used to connect the AC request signal.

AC Fan State
Fill the FAN action when AC On.

AC Turn on Water Pump
Turn on Water Pump when AC On.

AC Pressure Input
Input channel used to connect the AC pressure sensor signal.

AC Over Pressure
Lockout voltage for AC Over pressure, above this voltage AC is shut off. A fixed hysteresis of 0.196V is used, resulting in a reenable voltage of: Lockout voltage-0.196V.

AC Low Pressure
Lockout voltage for AC Low pressure, below this voltage AC is shut off. A fixed hysteresis of 0.196V is used, resulting in a reenable voltage of: Lockout voltage+0.196V.

AC Request Added RefDC/Steps
When AC request input is active, this reference Dc/Steps is added to current idle position/dutycycle.

AC Time Until Compressor ON
Delay time in miliseconds from AC request input active till compressure clutch is engaged.

AC Relay Type

  • Hold-Off: Relay output is active when AC requested only during the delay time, relay ON disables clutch engage
  • Engage: Relay is active when AC requested after delay has passed, relay ON enables clutch engage.

AC Compressor Relay Output / Channel
Match to compressor clutch relay output wire connection on ec18/ec36
