Boiler turns on everytime Air-Handler does

clammy

Hello forum...I have a Weil McLain P-WGO-4 boiler running my Hot Water and my Air Handler (First Co. 48MBXR-4HW). The HW tank, air-handler, and boiler are all within a few feet of one another. I've noticed that the boiler turns on each time the air handler gets a call for heat. The temp on the boiler reads 160 before and after the unit turns on. Is there a way to add a thermostat so that the boiler will only turn on if the water temp in the air handler gets too low? Seems like that's how it should be.

Thanks, Tim
