Temperature Regulation

IHKA E36 Temperature Regulation




Temperature regulation is accomplished the same way as on the IHKA systems already covered:

- solenoid actuated water valves control the flow of hot coolant through the heater cores
- the valves, sprung open, are powered closed by the control panel/module in response to sensed inputs and buttons pressed on control panel/module face.







An important difference from IHKA E31, and E38 is that IHKA E36 does not use an electric pump to boost coolant flow through the heater cores. Instead, the control panel/module monitors engine speed and compensates for low flow at lower engine speeds by increasing water valve "open" time.
