timer control replacement

I recently replaced my old mechanical timer with a Toro ECXTRA...all zones work except one which was working fine before the replacement. My system is very old and a sprinkler technican that came out to inspect said that the Toro timer did not produce enough amperage to open up some of the older solenoids. Any thoughts and if I should replace the Toro and if so, any recommendations, ie, are there units that have more. I notice that the Toro has a .3 amp output and that a Hunter has a 1. amp output...thanks

Some old valves can demand a full amp to open the solenoids. No inexpensive solid state controller exists that will operate them.

Wet Boots...would the Hunter that is rated at 1 AMP possibly work

The Hunter PRO-C would be a sound choice, but I prefer the Rain-Bird ESP-4M controller. The electro-mechanical controller you had, was it un-repairable?

the old timer was installed in 1959...I have no idea if anyone could repair...a real antique.

Do you know what model and make it was? I am a fan of the old mechanical controllers. Although they lacked some of the more modern features used in todays controllers, they made up for it in reliability in the end.

If you can post the make and model of the unit, I should be able to tell you if it is repairable or not.

It is an Imperial RIVT 6 station...output 24 V AC 60 cycles
transformer capacity 50 VA fuse 3amp whatever any of this means.

Well it was a shot, I am unfamiliar with Imperial. Maybe someone else on this forum is and can give you some insight on this controller.

One thing to consider, if you can't find a controller to handle the load of those old solenoids, you could possibly find a universal solenoid that will fit them and have a much lower inrush current draw. But I think you will do fine by getting a Rain-Bird ESP-4M controller (or Hunter Pro-C if you prefer). Here is the link for you to do some research on the Rain-Bird controller. ( www.rainbird.com/landscape/products/controllers/espmodular.htm )
Good luck!

That Imperial was likely repairable...I get them repaired or repair them myself quite often.....what was wrong with it?

Must be Imperial valves as well?

As Boots said, some of the old solenoids will not respond to the newer controllers...I am unaware of any solid state controllers that would be reliable in this capacity.

Hunter ICC has it, for one example. As for the Imperial Valet controllers, I've used them, and liked them. They can be repaired
<center></center>But at this point in time, there might be another direction to take, since you have a new clock already. This would be to upgrade the system with new control valves, if possible. It occurs to me that a system installed in 1959 might not have any backflow protection. On flat properties, a group of valves near the house can be replaced with antisyphon valves. If the valve is at least six inches higher than the highest sprinkler they feed, you have backflow prevention you can count on. This could actually cost you less than having the Imperial controller repaired.
