Great replacement for older installations
The PR-20411 is an exact replacement for my failed reed switches in my current alarm system. My system is about 25 yrs old and I took it over when I bought the house recently. Only a couple of the old sensors were bad. Some missing magnets. These exactly replaced the defective units.

Exact replacement part with actuator doors
1 of 1 found this helpful Exact replacement of the upper evaporator case. What I needed was a new heat cool door as the shaft on mine split as I see many have had the same problem. I was surprised to find this component at this affordable price. I did a little research before I removed the case to fix it. First I attempted to epoxy the shaft together which worked for about two days. Having had everything apart so soon before made the actual replacement easier, however not a real hard job but some skill and patience is required.
The pictures are the broken door, the new case along side the old one, the new case side view, the tools needed to replace it, the evap case in place before covers reinstalled.

Set it once and forget it.
The Intermatic ST01 has been around for quite a while. I have had a couple of them before but sold that house. prior to the ST01 I had a regular in wall astronomical timer but those had a problem with CFL bulbs that I was using. This timer has a different kind of switch inside powered by the battery that actually turns the devices on or off. This works for LED or CFL bulbs. The last one I just bought was used on ebay, for about half the usual list price which made it a great deal. There are instructions in PDF from Intermatic available and also numerous YouTube videos available. The programming is not real user friendly so need the instructions to be successful. I used mine in a three way switch application and works great.
