Vista 20P Control Panel and Peripheral Wiring
There are 25 terminals on the Vista 20P board, it sounds like a lot, but it's really very simple. We'll begin with the transformer connection on terminals 1 and 2, then progress on to describe each connection. Make sure not to plug in the transformer until all other connections are complete.

The transformer takes your 110 VAC outlet voltage and converts it into a low-voltage 16.5 VAC power source for the control panel. It's AC in, and AC out, so polarity is not a concern when wiring, either terminal of the transfomer can be wired to either terminal of the control.
The Vista 20P uses a 16.5 Volt 25 VA transformer. It has a fuse in it's secondary that can easily be blown, the fuse can't be replaced, so you may someday need a replacement transformer. This transformer is a direct replacement for your Vista 10, Vista 15P, and Vista 20P system.
