I won't be cooling UF circuits and the cooling coil is in AHU with ductwork to each room. I just plan to have cool air to bedrooms during hot summers. Probably going to use Viessmann ASHP, about 10KW, for heating and hot water. These can also be used for cooling and I will just T off ASHP F&R with 3 port valves which will be controlled by some kind of switching system. I'm wondering what the temperature range of these ASHPs is in the cooling mode? Is it adjustable and what's ideal temperature for use in AHU with chilled water coil? The AHU also has a heat exchanger coil and drip tray for condensate. Originally had a DX coil which I have removed and intend to replace with chilled water coil.

I've an AHU with heat exchanger for warm air and DX coil for cool air. The DX coil has never been used and I would like to replace this DX coil with chilled water coil so a new ASHP can occasionally supply cool air through the AHU . My CW coil fabricator wants to know the potential flow and return temperatures from the ASHP when it's in cooling mode. Is there a guide that will tell me that information for various ASHPs?
