IHKR Operation
IHKR system operation is as follows:
• Temperature Control - The desired interior temperature is set with the rotary knob on the
control panel. Control of the interior temperature is carried out electronically by the con-
trol module’s cycling of the water valve to regulate coolant flow through the heat
exchanger.
• Air Distribution - Air distribution is set mechanically through the use of gear linkages and
bowden cables. The air can be set for:
- Footwell or blended between footwell/face vent or footwell and defrost
- Defrost or blended between footwell/defrost or defrost/face vent
- Face vent or blended between face vent/footwell or face vent/defrost
• Blower Control - Blower fan speed is controlled through a final stage with infinitely vari-
able speed control.
The push buttons on the control panel are used to:
• Switch between fresh air and recirculating air inlet modes
• Request for A/C activation
• Activation of the rear window defogger
