you can do this by adding another hot water loop and changing the boiler with a fluid to fluid heat exchanger. You can then choose the control scheme of the heat exchanger to heating modulating and set the temperature on the supply side of the heat exchanger. This loop would serve the zone group with the garage.

you Hello,
This can do this be accomplished by adding another hot water loop and changing the boiler with to a fluid to fluid heat exchanger. Connect the boiler HW loop demand side to the HX of the second HW loop. You can then choose the control scheme of the heat exchanger to heating modulating and set choose the temperature OA reset setpoint manager and place it on the supply side of the heat exchanger. This loop would serve the zone group with the garage.
