Boiler Entering Water Temperature

I have a question about the boiler entering water temperature. I checked
the hourly report and found the boiler EWT is the environmental temperature if
the boiler is located outdoor. Can I change it to return water temperature from
the heating coils in the AHU? Your help is highly appreciated.

We are working on a project that has half the building running on 2-pipe
fan coils for heating only and the other half of the building on water
source heat pumps, connected to a condenser water loop.

There are two seperate loops, the hot water loop, which has 4 boilers,
and the condenser water loop, which has two fluid coolers. The two loops
are connected via a heat exchanger.

When the condenser water loop is in need of heat, it draws heat off of
the hot water loop.

Is there any way to simulate this system in eQUEST? I cannot find a way
to connect a heat exchanger between the condenser water loop and the hot
water loop.
