Logamatic 2107/Zones

Doug Thompson

I am installing a 2107 and want to control two heating zones with same water temperature. Circuit #1 is constant circulation with rads. and thermostatic heads. Zone #2 is an air handler controlled with wall stat. Do I need a zone relay such as the Taco SR502? If so, does the stat wire go to the relay and then on to the air handler?

Thanks for your help

Doug

Buderus has an Acrobat document available that covers a whole bunch of wiring options. Here's the link ...

You may have to type that in directly, or just go to their web site and click "Literature", then look for the HS2017 application note.
