type 44 heater valve

[kneale at coslink.net]

Electrical connection valves are NLA.  No problem running the HVAC system
without the electrics, far as I can tell.  The valve normally is open under
all circumstances except A/C use, when it closes via the vacuum system that
also opens the recirculation door.

I have '90 100, 90 200, 91 100.
Asking about the water heater valve. 
     the '91 100 has an electrical connection
     the '90 100 has the wirng but has not had a valve with electric since
I've owned it (several years)
     the  '90 200  no electrical connection on valve, don't remember seeing
any wiring.

So I ask, what is it for?  Does it need the connection?   
The non_electrical are a little shorter and it is a stretch to fit hoses.
Local flaps don't show a heater valve with an eclectrical connection in 
the listings.
