Heating Switchover Valve Question

Is there such a thing as a switchover valve located behind the CCU on a W123?

There is a set of "switchover valves" that reside next to the CCU. They are vacuum switches that are controlled by the CCU and they control the vacuum to the various pods.

Do any of them control power to the aux pump?
