Using chiller to temper WSHP loop

Can anyone share how to use chiller that supplies 44F to temper WSHP loop to operate at 85F? I have used the following configuration and cannot get intended temperatures.

At the main WSHP loop- image description Here is HX config image description At the primary cooling loop- image description

In real life, a tempering valve would accomplish this, but as I understand that tempering valve is not a solution for such situations in open studio/energy plus.
