Weil Mclain Ultra gas and 11 zones

Rich P_3

My co-worker is installing a WM 310. this building has 11 zones using honeywell ra89 relays ( no end switch). Can we easily configure the PHD control to run strictly off outdoor temp or flow or something. Or update the relays? Any input appreciated.

Is that an old W-M Ultra 310?

I ask because it is my understanding that the PhD control was last used in the Ultra-2 series, and the Ultra-3 series has been out about 2 years now. Ultra 3 boilers have a very different control. You may wish to seriously examine the installation manual on how to configure that.

Hi JD:

I didnt take the manual with me. I looked on line and the supplement said 2010.

I am not all that familiar with this set up. I typically install the System 2000

thanks for any help
