Delanair MK III hot problem

Delanair MK III hot problem
Hello!
When I set temp knob to manual and call for max cool with mode knob off, my heater valve doesn't close so the heat, thought little, pass in the cabin from the closed flaps of the heater matrix box!
The valve closes only if I set mode knob on low, norm or hight...
Is this normal?
I'd like to close heater valve without holdig blower fans on!
Please keep in mind that my A/C doesn't work because gas circuit is completely empty... Maybe is this the problem?
Thanks for the help!

The other thing is when on defrost you get full heat, really good when you need to defrost on a 30°C day.

This is not the exact same as mine but close
As long as the valve is normally closed and rated at 100°C it should work.

The Delanair system closes the heater valve when max cooling is called for.... and opens it in heating and blend modes.
It this function inoperative on your car or do you have a different rationale in mind?

The valve will also allow me to manually turn the heat off when I need defrost on a hot day so I don't get baked.
If I run the AC it's not a problem.
