GSHP (water-to-water) with radiant heating and cooling

Hello,

I'm currently using OS 2.9.1 and model a residential building in which I applied a GSHP (which should be reversible, that means it provides heating and cooling) and connected it successfully to my secondary radiant heating loop.

However, when I add a water-to-water Heat Pump cooling object and create a secondary radiant cooling loop, no cooling is provided. Temperature Setpoint managers are applied for both -heating and cooling. How can I fix that problem?

The closest solution I found and implemented successfully was similar to: https://unmethours.com/question/4823/how-to-model-gshp-with-radiant-floor-heating-in-openstudio/ where GSHP water-to-water for heating and water-to-air for cooling was used. But I would prefer if cooling is as well provided by a water-to-water object.

I would appreciate so much a fast answer on how to modify my preferred model that as well cooling is provided by only a water-to-water Heat Pumo!

(PS: I sensed that with a central heat pump system I could solve the problem, but I couldn't modify it accordingly that optimal zone conditions are ensured...)
