If the controller worked in its current location, then the electric/hydraulic converter will work in the same location. In the case of the normally closed system, which is quite rare since the 1960's (anywhere in the world), water pressure from the controller will open the valve. Lack of pressure will cause it to stay closed. A leaking control tube will probably cause the valve to remain closed even when actuated by the controller. Most hydraulic systems installed since the 60's were either Hydr...
I rebuild and repair Toro Custom and Monitor II controllers. My email is tim_daniels@hotmail.com
Yes, I have one used Freetime 4. I just checked it out and find it working well. I also have a few parts left over for Freetime (frames,springs, and MoM four station controllers (like the Freetime but running 120v instead of a plug in transformer--mainly clock motors and one used PV with the brass fittings).
If anyone is interested, I am rebuilding Toro Custom 8 and 11 hydraulic controllers as well as Toro Monitors for those who really need or want them. There are several options when considering what to do with your hydraulic sprinkler system now that they are being phased out and this is just one option to consider. Many of the components for these controllers are still available and you don't have to go through the expense of converting to electric or installing a new system to keep things green.
Actually for the day dial on any of the old Toro controllers from the old silver Moist o Matic to the Custom and Monitor with removable pine, will water with no pin in the day position on the dial. You are correct on the fourteen day wheel. Not quite as flexible as the electronic clocks.
