Intermatic Timer

PostBy: billw On: Wed Oct 01, 2008 9:30 pm

I bought an Intermatic timer from the EFM dealer I got my boiler from. The 520 manual shows the wiring for a Wilburt timer. I'm guessing the pin out is different on these two units. The wiring diagram shows pin 4 going to the ZR connection. Pin 4 on the Intermatic timer is the clock power. Is there a diagram that shows the wiring for the Intermatic timer?

Hook the load wire to the NO terminal, so when the tab on the clock dial moves the switch arm, power will flow to the desired device. Connect the neutrals/grounds in accordance to electrical code.

Hooking the load wire to the NC terminal would cause the device to run constantly, except for (2 min. per half hr.) The NC terminal is not used.
