Radiant DIY

Member Posts: 3
I have installed a radiant heat system. The boiler I chose is the Viessmann Vitodens 200-W Boiler B2HA-35. To control my three zones, I am using a Taco SR503.
I cannot figure out how to connect them so the Taco controls the Vitodens.
The Taco instructions refer to a "TT" connection on the boiler. The boiler instructions refer to a "remote" connection that is optional.
Also, the boiler instructions call for a rheostat that controls the temperature of the water with a 0-10 volt change. Is this necessary? If so, do I need to provide it voltage or simply install a rheostat between the leads?
Thanks in advance

The boiler does NOT come on from a demand signal from the SR503. It comes on based upon its ODR curve, water temp and parameter settings.
I'd recommend you contact Veissman tech support or find a contractor who's trained on that boiler and knows it.Bob Boan
