Modine and Taco

Rob_5 Member Posts: 9
Plan to install a modine hot water unit in garage.  Have 3 zones off boiler and adding a forth for modine. Have taco SR503 and picked up a SR501.  Not sure of wiring the SR501 with the 503? Picked up a Honeywell L606C for the fan on the modine.  Is this a straight forward line in to aquastat and line out to fan?  Install on return?  Thermostat on wall to Taco? Thank you. Rob
