Unhappy Connection between Honeywell L8148E and Amtrol W7HP

How do I connect Amtrol (with Smart Control) orange wires to the L8148E?

The way it is connected now is wires from Amtrol and the two wires from ARGO heat zone systems are connected together on the "TV" and "T" terminals on L8148E.

The Amtrol circulator fires up OK and I get hot water but after sometime, ER 2 shows up on the Smart Control panel. The instructions say that the inside temp. of water is at 155 F, where as the temp. is set at 120 F.

None of the 3 heat zones fires up.

How do I connect the two wires of Amtrol onto the L8148E.

Amtrol is in "Priority" mode.

Amtrol W7HP

I couldn't find anything on their web site about a W7HP. Is this some kind of boiler reset control?
