I have a issue with a laquerius water heater control. I recently had to replace a limiting control on a wiel mclain boiler. The bad control was a Honeywell 8148 with the water heater control tied to one of the poles on the temperature dial. I replaced this control with a Honeywell 7224U. I cant figure out where to make the connections. right now I have the 7224 maintaining a temp so the tank will always have hot water to work with. Any help would be greatly appreciated.
