rib relay help

RoosterBoy

hi this is what I was thinking of doing I have a buderus g115 with a 2107 control and a lt 160 hw tank set to dhw priority

sometimes when I get a call for heat my air handler will blow cold air when it's heating the dhw

so here is what I want to do

put a rib relay normally closed on the dhw taco 007 pump
and have it go to my air handler power

so when the pump is energized it will open the relay and that will not allow power to the air handler.
and when the pump is done it will close the relay and allow power back to the air handler now in the summer time I was
going to put a regular shut off switch between the relay and pump so I can keep the relay closed all summer long

will this work or is there a better way
thanks

24 volts

If possible could you wire it in so the air handle 24 v coil is interupted by a dhw call? Tstat wire is so much easier and safer to run than 120.

Fan will not run if pipe isn't hot

A simple snap disc

stat on the hw supply to the air coil would work, about 7 bucks. Get the adjustable type for more flexability.

Some air handlers actually have a mounting bracket for snap dics fan switches.
